TPS3700 Window Comparator With Internal Reference

for Overvoltage and Undervoltage Detection

1 Features

3 Description

The

TPS3700

wide-supply

voltage

window

•

Wide Supply Voltage Range: 1.8 V to 18 V

Adjustable Threshold: Down to 400 mV

High Threshold Accuracy:

comparator operates over a 1.8-V to 18-V range. The

device has two high-accuracy comparators with an

internal 400-mV reference and two open-drain

outputs rated to 18 V for over- and undervoltage

detection. The TPS3700 can be used as a window

comparator or as two independent voltage monitors;

the monitored voltage can be set with the use of

external resistors.

Low Quiescent Current: 5.5 µA (Typical)

Open-Drain Outputs for Overvoltage and

Undervoltage Detection

OUTA is driven low when the voltage at INA+ drops

below (V_ITP– V_HYS), and goes high when the voltage

returns above the respective threshold (V_ITP). OUTB

is driven low when the voltage at INB– rises above

V_ITP, and goes high when the voltage drops below the

respective threshold (V_ITP– V_HYS). Both comparators

in the TPS3700 include built-in hysteresis for filtering

to reject brief glitches, thereby ensuring stable output

operation without false triggering.
