In scenarios such as brushless DC (BLDC) motors, home appliance control, and speed measurement, Hall effect sensors have become the core components for magnetic signal sensing, leveraging the advantage of non-intrusive detection .
As one of the flagship products of Junmin Technology, the PT3602 general-purpose Hall effect latch features wide voltage compatibility, high stability, and compact size design . It perfectly balances performance and cost, emerging as a cost-effective choice in the industrial and consumer electronics sectors .
As a general-purpose Hall IC, the PT3602 precisely matches multi-scenario requirements in key parameters and functional design, with prominent core highlights:
1. Wide Voltage & Temperature Ranges for Complex Environments
The supply voltage covers 2.5V~18V, compatible with various power supply solutions such as lithium batteries and linear power supplies. No additional voltage conversion circuit is required, adapting to different power needs from portable devices to industrial controllers.
The operating temperature range reaches -40℃~+125℃ (for models with suffix "K"), and the storage temperature ranges from -50℃~+150℃. It can withstand the tests of high-temperature industrial environments and low-temperature outdoor scenarios, delivering maximum stability.
2. High Sensitivity & Low Drift for Accurate and Reliable Detection
Built-in dynamic offset cancellation function ensures excellent magnetic sensing symmetry. The typical operate point (BOP) is 30G, the typical release point (BRP) is -30G, and the hysteresis (BHYS) ranges from 20G to 100G, enabling precise capture of magnetic field changes.
Features low thermal drift, with minimal fluctuations in magnetic parameters when the ambient temperature changes. It ensures consistent detection during long-term use and avoids control errors caused by temperature drift.
3. Integrated Design & Strong Driving Capability to Simplify Circuits
Single-chip integration of sensor, preamplifier, and hysteresis comparator eliminates the need for additional signal processing circuits, simplifying hardware design.
The output terminal has a built-in pull-up resistor (6KΩ~14KΩ), which can be directly connected to the MCU interface without external resistors. With a maximum output current of 25mA, it can directly drive small loads, meeting the control needs of peripherals such as indicator lights and relays.
The typical output on-state voltage (VDS (ON)) is only 0.3V, resulting in lower power consumption and less energy loss.
4. Compact Package for Space-Constrained Layouts
Two mainstream package options are available to meet the space requirements of different products:
TO92-3L (UA model): Classic through-hole package with easy soldering, suitable for prototype development and through-hole technology products.
SOT23-3L (LH model): Surface-mount package with a compact size (typical dimensions: 2.9mm×1.8mm×1.1mm), ideal for high-density PCB layouts and miniaturized devices.
The versatility and reliability of the PT3602 enable it to perform effectively across multiple fields:
Motor Control: Speed detection and commutation control for Brushless DC (BLDC) motors, such as fans, water pumps, and small motor drives.
Consumer Electronics: Position detection for VCD/DVD loading mechanisms and CD/DVD-ROMs, as well as lid detection for home appliances (e.g., washing machine doors, microwave oven door controls).
Industrial Automation: Speed measurement and position positioning of mechanical equipment, as well as conveyor belt speed detection.
Home Security: Trigger detection for door/window magnetic sensors and safety alarm devices, along with non-contact switch control.
1. Easy-to-Use Application Circuit
The application circuit of the PT3602 is extremely simple. It can work stably with only a power supply filter capacitor (1μF decoupling capacitor is recommended) and a general diode, no complex peripheral components required. Even beginners can get started quickly. A decoupling capacitor connected in parallel at the power supply terminal can reduce voltage fluctuations, enhance anti-interference capability, and ensure stable detection signals.
2. Flexible Ordering and Supply Options
TO92-3L package (PT3602UAK): 1000 units/bulk, suitable for small-batch trial production and prototype development.
SOT23-3L package (PT3602LHK): 3000 units/reel, compatible with automated surface-mount production to meet mass supply needs.
Cost Advantage
The general-purpose design eliminates redundant additional functions, delivering outstanding cost-effectiveness. It is ideal for cost-sensitive mass production projects.
Strong Compatibility
Wide voltage and temperature ranges enable adaptation to different power supply environments and working scenarios, reducing component replacement costs.
Efficient Development
Integrated design simplifies circuits, and diverse package options fit various product forms, shortening the R&D cycle.
High Reliability
Features such as low thermal drift, built-in pull-up resistors, and strong overcurrent capacity reduce product failure rates and extend service life.
With core advantages of "wide compatibility, high precision, simple design, and low cost", the PT3602 Hall Effect Latch perfectly covers the magnetic sensing needs of multiple fields such as consumer electronics, industrial control, and home security. Whether for motor speed detection, position positioning, or non-contact switch control, it can provide a stable and reliable solution, making it a cost-effective choice for engineers during component selection.
