Product Overview

The MAX6751KA31+T is a low power microprocessor (μP) reset circuit with capacitor adjustable reset and watchdog timeout delay in 8 pin SOT-23 package. This microprocessor (μP) supervisory circuit monitors single/dual system supply voltages from 1.575V to 5V and provides maximum adjustability for reset and watchdog functions. It has fixed and adjustable reset threshold voltages using external resistors. The MAX6751 asserts a reset signal whenever VCC supply voltage or RESET IN falls below its reset threshold or when manual reset is pulled low. The reset output remains asserted for reset timeout period after VCC and RESET IN rises above the reset threshold. The reset and watchdog delays are adjustable with external capacitors. The MAX6751 contains watchdog select input that extends the watchdog timeout period by 128x. It is available with active-low, open drain RESET output. It is typically used in intelligent instruments, battery powered computers/controllers and embedded controllers.
  • Supply voltage range from 1V to 5.5V at TA = 0°C to +125°C
  • Automotive temperature range from -40°C to 125°C
  • 3.7μA supply current (VCC ≤ 2V) reduces system power consumption
  • Integrated power supply protection increases robustness
  • Power supply transient immunity
  • RESET (complementary) valid for VCC ≥ 1V
  • Reset timeout period of 7.59ms (CSRT = 1500pF)
  • Fixed VCC threshold of 3.075V
  • Normal watchdog timeout period of 7.59ms and extended watchdog timeout of 971.5ms (CSWT = 1500pF)
