1 Adopts IMC-Hall® technology for high-performance magnetic field sensing

2 Supports very high and extra high field variants with measurement range from ±8 to ±333mT

3 High-speed sensing: DC to 400kHz bandwidth with 2µs short response time

4 High linearity up to ±0.5% full scale for accurate measurements

5 AEC-Q100 Grade 0 automotive qualified, suitable for harsh automotive environments (-40°C to150°C)

6 Low thermal drift: offset drift <5mV, sensitivity drift <1.5% over wide temperature range

7 Dual overcurrent detection: internal threshold (fast response for short-circuit) and external threshold (customizable via voltage divider)

8 Flexible supply voltage: factory-selectable 5V or3.3V mode

9 Selectable analog output: ratiometric (scales with supply) or fixed (Vref-based)

10 End-of-line programmable: offset, sensitivity, filtering, internal overcurrent threshold can be calibrated

11 RoHS compliant, packaged in SOIC-8 with MSL-3 moisture sensitivity level

1 Redundant current monitoring in battery management systems (BMS)

2 Phase and DC link current measurement in high voltage traction motor inverters

3 Current sensing in 48V boost recuperation inverters (phase and DC link)

4 Current measurement in DCDC converters

5 Overcurrent detection and current monitoring in smart battery junction boxes

6 Overcurrent protection in smart fuse applications

7 Suitable for other automotive power electronics systems requiring high-speed, accurate current sensing

1 Do not exceed absolute maximum ratings: supply voltage ±8V/-0.3V, junction temperature165°C (permanent damage may occur)

2 Handle with ESD control procedures to prevent electrostatic discharge damage

3 Power-on delay of1ms: output signal is not valid during this period

4 Reference voltage pin (VREF) should be connected with resistance >200kΩ to ensure correct voltage measurement

5 Output capacitive load is optimized for4.7nF (max6nF for stability)

6 Unused NC pins should be connected to GND to improve EMC performance

7 For overcurrent detection: OCDINT requires at least1µs input holding time, OCDEXT requires10µs

8 If OCD pins are not used, connect them to GND

9 Soldering guidelines: follow IPC/JEDEC standards (reflow for SMD packages)

10 Moisture sensitivity level3: adhere to J-STD-020 for storage and handling

11 Not suitable for high-reliability applications like medical life-support or avionics systems

12 Export control regulations may apply; check local laws before export
