ACS770
Overview
The Allegro™ ACS770 family of current sensor ICs provides economical and precise solutions forAC or DC current sensing. Typical applications include motor control, load detection and management, power supply and DC-to-DC converter control, inverter control, and overcurrent fault detection.
- Industry-leading total output accuracy achieved with new piecewise linear digital temperature compensation of offset and sensitivity
- Industry-leading noise performance through proprietary amplifier and filter design techniques
- 120 kHz typical bandwidth
- 4.1 µs output rise time in response to step input current
- Integrated shield greatly reduces capacitive coupling from current conductor to die due to high dV/dt signals, and prevents offset drift in high-side, high-voltage applications
- Greatly improved total output error through digitally programmed and compensated gain and offset over the full operating temperature range
- Small package size, with easy mounting capability
- Monolithic Hall IC for high reliability
- Ultralow power loss: 100 µΩ internal conductor resistance
- Galvanic isolation allows use in economical, high-side current sensing in high-voltage systems
