ACS37600: 400kHz, High-Precision Linear Sensor IC with Vref and Overcurrent Fault

The ACS37600 is a Hall-based linear sensor in surface mounted TSSOP8 package developed for corebased current sensing applications.

The 400kHz Bandwidth, bidirectional Vref pin, Overcurrent Fault and high accuracy signal path with low noise make it suitable for demanding Industrial applications.

The wide sensitivity range (0.8 to 18mV/G), programmable Bandwidth (100kHz to 400kHz) and programmable sensitivity over temperature (for concentrator core drift compensation) enables users to rapidly develop flexible, highly programmable Current Sensing Modules all with one IC.

The user programmable, bidirectional reference voltage pin (Vref) enables constant monitoring of the zero-current voltage and easy interfacing with 3.3 V and 5 V ADCs.

A very fast overcurrent fault response time (1.5 μs typ.)  increases safety by protecting against system short circuits. Finally a non-ratiometric output and a supply pin that can survive 15V, make the ACS37600 extremely immune to noisy supply conditions.

• User programmable bandwidth (100 to 400 kHz) 
• Very fast response time (<1.25 μs typ.) 
• User programmable, bidirectional reference pin (VREF)
• User-programmable overcurrent fault (OCF)
