Description
The ACS760 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 I
2
R losses in the
power path are reduced.
When the ACS760 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 a fault is detected, the
gate is disabled while simultaneously alerting the application
that a fault has occurred.
The integrated protection in the ACS760 incorporates three
levels of fault protection, which includes a Power Fault with
user-programmable delay, a user-programmable Overcurrent
Fault threshold with programmable delay, and Short Circuit
protection, which disables the gate in less then 2
μ
s.
Additionally, in the event the external high-side FET fails
short, the ACS760 detects the S1 Short failure and immediately
disables the gate and alerts the host system. Unlike the three
protection faults, cycling the EN pin does not reset the S1 Short
failure. Power to the device must be cycled.

RV1 is required only for inductive loads.
D1 should be a Schottky for inductive loads, to eliminate over-stress of the ACS760.
FB– is tied to GND at the point of load.
