TPS3701 36-V Window Comparator with Internal Reference

for Over- and Undervoltage Detection

1 Features

3 Description

The

TPS3701

wide-supply

voltage

window

•

Wide Supply Voltage Range: 1.8 V to 36 V

Adjustable Threshold: Down to 400 mV

comparator operates over a 1.8-V to 36-V range. The

device has two precision comparators with an internal

400-mV reference and two open-drain outputs (OUTA

and OUTB) rated to 25 V for over- and undervoltage

detection. Use the TPS3701 as a window comparator

or as two independent voltage monitors; set the

monitored voltage with the use of external resistors.

Open-Drain Outputs for Over- and Undervoltage

Detection

•

Low Quiescent Current: 7 µA (typ)

High Threshold Accuracy:

–

0.75% Over Temperature

0.25% (typ)

OUTA is driven low when the voltage at the INA pin

drops below the negative threshold, and goes high

when the voltage returns above the positive

threshold. OUTB is driven low when the voltage at

the INB pin rises above the positive threshold, and

goes high when the voltage drops below the negative

threshold. Both comparators in the TPS3701 include

built-in hysteresis for noise rejection, thereby

ensuring stable output operation without false

triggering.

•

Internal Hysteresis: 5.5 mV (typ)

Temperature Range: –40°C to 125°C
