Allegro's coreless current sensor solutions meet the demanding current monitoring requirements of modern electronic devices, especially in automotive and industrial applications, by providing high accuracy, high bandwidth, and small size current measurement capabilities.
Our solution
The ACS3761X Hall Effect Sensor IC Solution family is a coreless and shieldless solution that reduces the size and weight of the BOM and the overall inverter. These differential sensors reject stray magnetic fields, reducing software dependency. The family is optimized for high current ranges from 100 A to >4000 A, making it ideal for automotive applications.
Product Benefits
- No concentrator core or shield required.
- Contactless, lossless current sensing for applications where current flows through busbars or PCBs.
- Differential sensing eliminates common-mode stray magnetic fields 3.3 V and 5.0 V single supply operation.
- Monolithic Hall ICs offer high reliability and sensor bandwidth up to 240 kHz.
- Factory trimmed sensitivity and offset for improved accuracy.
