Description: 12V High-Side Hot-Swap Hall Effect Based Current Monitor

Features

* ▪ Hall-effect current monitor
* no external sense resistor required ▪ PGOOD and ¯P¯¯G¯¯¯O¯¯O¯¯¯D¯ indication ▪ Analog output voltage (factory trimmed for gain and offset) proportional to applied current ▪ External high-side FET gate drive ▪ 240V
* A power fault protection with user-selectabl

Applications

* By eliminating the need for a shunt resistor, the I2R losses in the power path are reduced. When the ACS761 is externally enabled, and the voltage rail is above the internal UVLO threshold, the internal charge pump drives the gate of the external FET. When the load voltage reaches its target value
