3 Description
The INA301-Q1 includes both a high common-mode,
current-sensing amplifier and a high-speed
comparator configured to provide overcurrent
protection by measuring the voltage developed
across a current-sensing or current-shunt resistor and
comparing that voltage to a defined threshold limit.
This device features an adjustable limit-threshold
range that is set using a single external limit-setting
resistor. This current-shunt monitor measures
differential voltage signals on common-mode voltages
that can vary from 0 V up to 36 V, independent of the
supply voltage.
The open-drain alert output can be configured to
operate in either a transparent mode, where the
output status follows the input state, or in a latched
mode, where the alert output is cleared when the
latch is reset. The device alert response time is under
1 µs, allowing for quick detection of overcurrent
events.
This device operates from a single 2.7-V to 5.5-V
supply, drawing a maximum supply current of 700 µA.
The device is specified over the extended operating
temperature range of –40°C to +125°C, and is
available in an 8-pin VSSOP package.
