Overview
The TPS3700DDCR2, produced by Texas Instruments, is a wide-supply window voltage detector. This device operates over a broad supply voltage range of 1.8 V to 18 V, making it versatile for various applications. It features two high-accuracy comparators with an internal 400-mV reference and two open-drain outputs rated to 18 V. The TPS3700 can be used either as a window voltage detector or as two independent voltage monitors, with the monitored voltages set using external resistors. The device includes built-in hysteresis to filter out brief voltage glitches, ensuring stable output operation without false triggering.
