High-Side Hot-Swap Hall-Effect-Based Current Monitor IC

QSOP-24 package, hot swap controller ic, high side current monitor ic, voltage monitor icThe 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.

The ACS761 has an internal charge pump that drives the gate of the external FET. When the load voltage reaches its target value PGOOD is asserted high.

The integrated protection in the ACS761 incorporates three levels of fault protection, which includes a Power Fault with user-selectable delay, an Overcurrent Fault threshold with user selectable delay, and Short Circuit protection, which disables the gate in less than 2 µs.

Please see the datasheet for advanced features and benefits of the ACS761 device.
