概述
Description
The TPS3707-33DGNR is TI’s fixed-threshold voltage supervisor (power-on reset) with a 3.3 V trip point. It monitors Vcc and asserts its reset output whenever the supply falls below 3.3 V or during power-up/power-down transients, ensuring a clean microcontroller/system startup. It includes built-in debounce/hysteresis for noise rejection, offers very low quiescent current, and comes in TI’s compact DGNR package. Typical uses include microcontrollers, FPGAs/logic, and battery-powered or automotive applications that require a robust POR signal. For exact pinout, reset-output polarity, delay characteristics, and current consumption, check the TPS3707-33DGNR datasheet and TI product page.
