SBOS613B – FEBRUARY 2014 – REVISED APRIL 2016 INA300 Overcurrent-Protection, Current-Sense Comparator
1 Features 3 Description Designed for overcurrent protection applications, the
INA300 is a current-sensing comparator that detects
overcurrent by measuring the voltage developed
across a shunt resistor, and comparing that voltage to
the threshold voltage input level. The device
measures this differential voltage signal on commonmode voltages that can vary from 0 V up to 36 V,
independent of the supply voltage. The device
features an adjustable threshold range that is set
using a single external limit-setting resistor. A
selectable hysteresis feature enables adjustable
operation of the comparator to accommodate the
wide input signal range of 0 mV to 250 mV. 1 Wide Common-Mode Range: 0 V to 36 V
Selectable Response Times:
– 10 µs, 50 µs, 100 µs
Programmable Threshold:
