PT5607 PT5606

Trusted Solution for Motor Drives & Inverters

In high-voltage application scenarios such as PMSM/BLDC motor drives, power tools, and switching power supplies, the performance of the gate driver IC directly determines the operational stability of power devices (MOSFETs/IGBTs) and system efficiency.

As one of the flagship products of Junmin Technology, the PT5606/PT5607 600V high-voltage gate driver IC has become the preferred solution for high-voltage power system design, thanks to its core advantages of high voltage tolerance, strong driving capability, and comprehensive protection.

Key Advantages: High-Voltage Adaptability & Powerful Driving – Performance Meets Safety

As part of the same series of high-voltage gate driver ICs, the PT5606 and PT5607 share highly consistent core parameters with only a difference in input logic phase. Both are engineered to meet the rigorous requirements of high-voltage power system applications:

1. High-Voltage Tolerance for Wide-Voltage Scenarios

The high-side channel supports a maximum operating voltage of 600V, easily adapting to high-voltage applications such as electric bicycles and industrial inverters without the need for additional high-voltage isolation design.
The gate drive supply voltage ranges from 10V to 20V, compatible with the gate power supply requirements of mainstream power devices and eliminating the need for custom power modules.
Boasts a dv/dt immunity of 50V/ns, capable of withstanding negative transient voltage shocks. It maintains stable output in power conversion scenarios with rapid voltage changes, preventing false triggering.

2. Powerful Driving Capability + Precise Timing for Enhanced System Efficiency

Delivers robust output driving capability with IO+ up to 290mA and IO- up to 620mA. The high-pulse current buffer stage enables fast driving of MOSFET/IGBT gates, shortening switching time and reducing switching losses.
Integrated fixed dead-time protection of 0.5μs effectively prevents shoot-through current caused by simultaneous conduction of high-side and low-side bridge arms, eliminating the need for additional software configuration and simplifying timing debugging.
Matched propagation delay across all channels ensures synchronization of high-side and low-side drive signals, avoiding efficiency degradation of power devices due to timing deviations.

3. Comprehensive Protection for Maximum Safety

Incorporates Undervoltage Lockout (UVLO) functionality. When the gate supply voltage drops below the threshold (PT5606: VCCUV+ 8.6V, VCCUV- 7.8V; PT5607: VCCUV+ 8.1V, VCCUV- 7.2V), the drive output is automatically cut off to prevent excessive conduction losses in power devices caused by insufficient gate voltage.
Built-in shoot-through protection circuit eliminates the risk of simultaneous conduction of high-side and low-side bridge arms at the hardware level, reducing the probability of system burnout.
Low di/dt gate drive design enhances system noise immunity and minimizes the impact of Electromagnetic Interference (EMI) on surrounding circuits.

4. Flexible Compatibility to Lower Development Barriers

Supports multi-level input logic of 3.3V/5V/15V, directly compatible with the I/O ports of mainstream MCUs and DSPs without the need for level-shifting circuits.
Features an SOP8L package with a simplified pin layout, reducing PCB design complexity and enabling high-density power board layouts.
Operates over a wide temperature range of -40℃ to 125℃. The industrial-grade temperature tolerance adapts to harsh operating environments, ensuring stable performance in both high-temperature motor compartments and low-temperature outdoor equipment.

Key Distinction of PT5606 vs. PT5607: Input Logic for Diverse Control Needs

The two devices share highly similar core functions, with the only key difference lying in the phase characteristics of the low-side input logic. They can be flexibly selected based on the system control scheme.

Features	PT5606	PT5607
Low-Side Input Logic (LIN)	Inverting Input	Non-Inverting Input
Undervoltage Lockout Threshold (VCC)	Upper Limit: 8.6V Lower Limit: 7.8V	Upper Limit: 8.1V Lower Limit: 7.2V
Core Application Scenarios	Half-Bridge System Requiring Logic Inversion Control	Half-Bridge System Requiring Logic In-Phase Control

This differentiated design enables engineers to adapt to different MCU control logics merely by selecting component models without modifying the hardware circuit, thus enhancing the flexibility of the solution.

Typical Application Scenarios: Covering the Core Fields of High-Voltage Power Control

The high performance and reliability of the PT5606/PT5607 enable them to play a core role in various high-voltage power applications:

1. Motor Drive Field: PMSM/BLDC Motor Control

In scenarios such as electric bicycles, power tools, and industrial servo motors, the two devices can serve as the gate drive core of half-bridge topologies, driving MOSFETs/IGBTs to achieve precise speed regulation and commutation of motors. The 600V high-voltage tolerance adapts to battery pack power supply, the strong driving capability shortens the motor start-up response time, and the undervoltage protection and shoot-through prevention functions ensure long-term stable operation of motors, avoiding device damage caused by voltage fluctuations or control errors.

2. Power Electronics Field: General-Purpose Inverters

In equipment such as industrial inverters and photovoltaic inverters, it is necessary to convert low-voltage DC power to high-voltage AC power. The PT5606/PT5607’s 600V high-voltage adaptability and 50V/ns dv/dt immunity can maintain stable driving during high-frequency power conversion, improving the conversion efficiency and reliability of inverters. At the same time, the built-in protection functions simplify the system safety design.

3. Power Supply and Lighting Field: Switching Power Supplies, High-Voltage Lighting Drives

In high-voltage switching power supplies (such as industrial power supplies and medical power supplies) and high-voltage lighting equipment, the two devices can drive power devices to achieve efficient energy conversion. The wide-voltage gate power supply and multi-logic level compatibility adapt to different power supply topologies and control chips, and the miniaturized SOP8L package can also meet the compact layout requirements of power supply modules.

Selection and Application Recommendations: Enhancing Design Efficiency

1. Selection Key Points

Choose based on control logic phase: Select PT5607 if the MCU output is in-phase with the low-side drive requirement; select PT5606 for anti-phase.

Select according to supply voltage: Prioritize PT5606 (with a wider undervoltage threshold range) if the system VCC voltage fluctuates significantly.

Confirm power device matching: Ensure the drive current (290mA/620mA) matches the gate charge requirement of the MOSFET/IGBT to avoid insufficient driving capability.

2. Application Design Notes

Power supply filtering: Connect decoupling capacitors in parallel with the VCC and VB pins to suppress power supply fluctuations and enhance anti-interference capability.

Wiring specifications: Separate the wiring of the high-voltage side (VB, VS, HO) from the low-voltage side (VCC, HIN, LIN) to reduce electromagnetic coupling interference.

Heat dissipation design: Although the device itself has low power consumption, it is recommended to reserve appropriate heat dissipation space in high-frequency operating scenarios to ensure long-term stable operation.

With core advantages of 600V high-voltage tolerance, robust driving capability, and comprehensive safety protection, the PT5606/PT5607 perfectly meet the rigorous requirements of high-voltage power control scenarios. Whether for motor drives, inverters, or high-voltage power supply designs, these two devices simplify circuit design, enhance system reliability, and lower development barriers, making them a cost-effective choice for engineers.
