INA301A3IDGKT Texas Instruments, Comparator, Open Drain O/P, 1μs 5.5 V 8-Pin VSSOP

The Texas offers a INA series which includes both a high common-mode, current-sensing amplifier and a high-speed comparator configured to detect overcurrent conditions through measuring the voltage developed across a current-sensing or current-shunt resistor and comparing that voltage to a defined threshold limit.

High accuracy amplifier
Dual output of amplifier and comparator output
Programmable alert threshold set through a single resistor
