PST11D

Overview

This IC is a 40V withstand voltage 1ch voltage detection IC that is ideal for monitoring the voltage of car batteries.
The voltage detection accuracy is ± 2% including temperature fluctuation, and the output form is Nch open drain output.The current consumption is 1.7 μA (typ.) And the operating temperature range is -40 to 105 ° C.
The detection delay time and release delay time can be set with external capacitors.

Application

・Voltage monitor for car battery
・Voltage monitor for AC / DC converter output voltage

Features
