HBCT
Automotive current sensor for battery management systems
HBCT - Automotive current sensor
The HBCT family provides to an engine control unit (ECU) the actual value of current flowing in and out of the battery and the ambient temperature by a NTC thermistor. The current measurement is performed with a full galvanic separation between the primary circuit (high power) and the secondary circuit (electronic circuit).
The HBCT 250-V proposed a battery clamp mounting and the transducer is linked to the ECU with the wiring harness using a waterproof connector.
HBCT current sensors are relying on the hall effect technology. They are designed for automotive applications.
HBCT – Features and benefits

Main characteristics
- Open Loop transducer using the Hall effect
- Unipolar +5 V DC power supply
- Primary current measuring range up to −250 A / +100 A
