Introduction

AI Translation

LKQ7933xST is a family of low-voltage power supply monitoring circuits with manual reset and watchdog functions, designed for power-on reset and power-down protection of digital controllers such as processors or MCUs. The watchdog timer clears when RESET# is asserted or the watchdog is toggled; as long as RESET# is not asserted, the watchdog continues counting. This family provides an open-drain, active-low reset output.

Features

AI Translation
  • Supply voltage range: 1.2V ~ 5.5V
  • Reset delay time: 140ms (minimum)
  • Watchdog period: 1.6s
  • Manual reset function
  • Reset output: open-drain, active-low (RESET#)
  • Multiple selectable reset threshold voltages: 3.08V (LKQ7933TST), 2.93V (LKQ7933SST), 2.63V (LKQ7933RST)
