About AKM
EZ232L Series
Achieves a coreless design while maintaining performance equivalent to cored current sensors.
It enhances design flexibility and contributes to further space savings in system design by reducing the sensor size.
EZ232L series
Overview
- High resolution: 1 Arms
- Fast response time: 500 ns
- Non-contact current sensing
- AEC-Q100 compliant
What can be done with EZ232L series?
- Improves system efficiency
- System downsizing
- Fast overcurrent detection
Features
1. Contributes to significant reductions in system size and weight
The EZ232L series is a field current sensor featuring a coreless design with an external busbar, capable of accurately measuring extremely high currents—up to several kiloamperes.
By realizing a coreless structure without a magnetic core, the sensor enables significant reductions in overall system size and weight compared with conventional cored current sensors.
2. Energy efficiency improvement at low‑torque operation through high‑resolution sensing
By leveraging the low-noise characteristics of AKM’s high-sensitivity compound Hall elements, the sensor achieves high resolution of approximately 1 Arms even at current levels of several hundred amperes.*
This enables high energy efficiency even during low-torque operation in electric vehicle.
*Resolution depends on the busbar structure. For details, please refer to the PoC Reference documentation.
3. Enhanced system safety with fast overcurrent detection
High‑sensitivity compound Hall elements enable a fast 500 ns response, ensuring safe overcurrent detection in next‑generation electrified vehicle powertrains based on SiC and GaN devices.
Applications
- Traction inverter
- DCDC converter
- SST (Solid State Transformer)
- Electronic fuse (eFuse)
