Overview
The TPS3701DDCR, produced by Texas Instruments, is a high-voltage window voltage detector designed for over- and undervoltage monitoring. This device operates over a wide supply voltage range of 1.8 V to 36 V, making it versatile for various applications. It features two precision comparators with an internal 400-mV reference and two open-drain outputs rated to 25 V. The TPS3701 can be used as a window voltage detector or as two independent voltage monitors, allowing for adjustable threshold settings using external resistors.
