ACS761ELF-20B Datasheet (Allegro Micro Systems) - 12V High-Side Hot-Swap Hall Effect Based Current Monitor

ACS761ELF-20B, 12V High-Side Hot-Swap Hall Effect Based Current Monitor

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.

When the ACS761 is externally enabled, a
