ACS761ELF-20B-T Current monitor

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 PGOOD is asserted high. When a fault is detected, the gate is disabled while simultaneously alerting the application that a fault has occurred.

The ACS761 combines Allegro? Hall-effect current sense technology with a hot-swap controller resulting in a more efficient integrated controller for 12 V applications. By eliminating the need for a shunt resistor, the I2R losses in the power path are reduced.
