ACS760ELF-20B - High-Side Hot-Swap Hall Effect Based Current Monitor

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 I2R losses in the power path are reduced.

Features

Hall-effect current monitor.
no external sense resistor required.
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-programmable delay.
User programmable Overcurrent Fault Protection with programmable delay.
1.5 mΩ internal conductor resistance.
Short Circuit Protection isolates failed supply from output in < 2 µs.
Active low Fa.
