General 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.

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.

Overview

ACS760ELF-20B 12 V High-Side Hot-Swap Hall-Effect-Based Current Monitor.

Key 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.
