Automotive-Grade Digital Latch Hall Effect Sensor IC – KTH2562L Series

产品介绍

With continuous iteration of automotive electrification, power tools and intelligent actuators, magnetic sensing ICs are required to meet multiple stringent standards including wide voltage range, wide temperature coverage, high reliability and robust protection.

Junmin Technology partners with the original manufacturer Kuantai Core to launch the KTH2562L series, an AEC-Q100 qualified automotive-grade digital bipolar latch Hall sensor. Equipped with chopper stabilization technology and built-in multi-protection circuits, the device supports an ultra-wide operating voltage of 3.8 V to 60 V and delivers stable output across the full temperature range of -40 ℃ to 150 ℃. It provides an all-in-one solution to resolve position and rotational speed sensing challenges for applications such as car windows, tailgates, brushless DC motors and valve detection, delivering cost-effective domestic magnetic sensing solutions for automotive Tier 1 suppliers and industrial equipment manufacturers.

Built on Robust Automotive-Grade Foundation, Stable Operation Under Harsh Environments

English Translation (Professional Datasheet Style)

Vehicle power fluctuation, extreme temperature differences, ESD surges and reverse power connection are the major root causes of failure for automotive sensors. The KTH2562L delivers comprehensive hardware-level protection and complies with the AEC-Q100 automotive qualification standard:

Ultra-wide Temperature Range for Full Vehicle Operating Conditions

It operates steadily from -40 ℃ to 150 ℃ without parameter drift during cold start in frigid outdoor environments or high-temperature engine bay operation. The BRP tolerance is limited to only ±10% across the entire temperature spectrum. Adopting chopper stabilization and on-chip temperature compensation circuits, it eliminates the drawbacks of conventional Hall sensors, including sensitivity degradation at high temperatures and signal offset at low temperatures.

Premium ESD Protection

It features 6000 V HBM ESD and 500 V CDM ESD ratings, effectively preventing electrostatic breakdown during vehicle wiring harness plugging/unplugging and factory assembly, which significantly reduces production defect rates.

Dual Hardware Protection: Reverse Power & Output Overcurrent

The VCC pin withstands reverse voltage up to -40 V, so the chip remains intact even if power supply polarity is reversed. An integrated OCP overcurrent limiter clamps the sink current at 45 mA. It automatically limits current under short-circuit or load surge conditions and resumes normal operation once faults are cleared.

Wide Voltage Design 3.8 V ~ 60 V Without External Regulators

No external LDO voltage regulator is required. It is directly compatible with 12 V/24 V automotive power supplies and high-voltage power supplies for power tools. This simplifies the peripheral BOM, saves PCB layout space and cuts overall material costs of end products.

封装图&典型应用电路

Dual Bipolar Latch Design with Two Sensitivity Options for Flexible Selection

English Translation (Datasheet Standard Version)

The KTH2562L is a digital bipolar latch Hall sensor capable of detecting both north and south magnetic poles. It retains its output state after the magnetic field is removed, eliminating the need for a continuous magnetic field to hold the signal, enabling accurate and stable rotational speed counting and position latching detection.

Two Magnetic Sensitivity Grades for Custom Selection

KTH2562LA (20 Gs)BOP=±20 G, BRP=∓20 G. Suitable for low-magnetic-field applications and close-range detection with small magnets. It features a magnetic hysteresis of 40 Gs to resist stray magnetic interference.
KTH2562LC (50 Gs)BOP=±50 G, BRP=∓50 G. Designed for strong magnetic field and long-distance detection scenarios. It suppresses electromagnetic noise from motors and fits sensing structures with large air gaps.

High-Speed Response with Clean & Stable Signal Output

The power-up time is merely 8 µs, enabling instant magnetic field detection upon device startup with zero delay.

Adopting open-drain NMOS output with a maximum sink current of 45 mA, it can directly drive relays and MCU I/O ports.

It delivers excellent rise/fall edge speed of output signals. When paired with a simple RC filter, it fully meets the requirements of high-frequency rotational speed sampling.

Full Coverage of Multiple Packages to Adapt to Diverse Structural Designs

All series feature standardized 3-pin definitions, differentiated only by package outline with consistent pin logic. Seamless replacement and switching are supported, compatible with both SMD surface-mount and through-hole manufacturing processes.

PCB Layout Friendly:

Copper traces underneath the chip will not interfere with magnetic fields. Place the bypass capacitor close to the device to suppress power supply noise. Official standard application circuits are provided to help engineers accelerate design implementation.

Full-Scenario Deployment, Dual Coverage for Automotive & Industrial Markets

Main Automotive Applications

Sunroof / tailgate / sunshade curtain controllers, seat adjustment motors, window lifters, status detection of valves and solenoid valves, rotational speed & position sensing, in-place detection of vehicle body actuators

Industrial & Power Tool Applications

Commutation of brushless DC motors, flow meters, valve position feedback, proximity sensing, rotational speed detection for power tools, limit switches for automation equipment.

An additional low-cost two-wire solution is supported: pull the output up to the supply voltage, and signal acquisition is realized via total supply current. This reduces wiring harness complexity and is suitable for low-cost small actuators.
