ACS760ELF-20B中文资料ALLEGRO数据手册PDF规格书

描述 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 and Benefits

▪ 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 Fault indicator output signal

▪ External FET failure detection with active low S1 Short failure indicator output signal

▪ User controlled soft start / hot-swap function

▪ Logic enable input pin

▪ 10.8 to 13.2 V, single-supply operation

▪ 2 kV ESD protection for all pins
