Littelfuse CH1B032B Current Sensor
Littelfuse CH1B032B Current Sensor utilizes open-loop Hall effect technology to provide a ratiometric output signal proportionate to the magnetic flux density generated by the C-core. This Littelfuse current sensor offers digital output for ASIL C integration. The CH1B032B is designed for battery management systems (BMS) and features high sensing accuracy, low thermal offset drift, and low thermal sensitivity drift.
