Allegro MicroSystems' ACS759 family of current sensors provides economical and precise solutions for AC or DC current sensing in 3.3 V supply applications. For 5 V, applications use the ACS758 family of parts. Typical applications include motor control, load detection and management, power supply and DC-to-DC converter control, inverter control, and overcurrent fault detection.
| Features |
|
|
- Industry-leading noise performance through proprietary amplifier and filter design techniques
- Integrated shield greatly reduces capacitive coupling from current conductor to die due to high dV/dt, and prevents offset drift in high-side, high voltage applications
- Output voltage proportional to AC or DC currents
- Galvanic isolation allows for economical, high-side current sensing in high voltage system
