TPS3700-Q1 is an Automotive, High-Voltage (18V) Window Comparator with Over- and Under-Voltage Detection

This post sponsored by Texas Instruments.

The TPS3700-Q1 wide-supply voltage window 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 overvoltage and undervoltage detection. The TPS3700-Q1 device 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. The OUTA terminal is driven low when the voltage at the INA+ terminal drops below (VIT+ – Vhys), and goes high when the voltage returns above the respective threshold (VIT+). The OUTB terminal is driven low when the voltage at the INB– terminal rises above VIT+, and goes high when the voltage drops below the respective threshold (VIT+ – Vhys). Both comparators in the TPS3700-Q1 device include built-in hysteresis for filtering to reject brief glitches, thereby ensuring stable output operation without false triggering. The TPS3700-Q1 device is available in a Thin SOT23-6 package and is specified over the junction temperature range of –40°C to 125°C.
