LTC2954ITS8-1 General Description

LTC2954ITS8-1 is a low power, wide input voltage range power supply monitor with a built-in timer, manufactured by Analog Devices Inc.



  • It has a wide operating input voltage range from 1.6V to 36V.
  • The quiescent current consumption of the device is very low, which is 1.6uA typical and 2.5uA maximum.
  • The device is capable of monitoring an input supply voltage and asserting a reset signal if the voltage falls below a programmable threshold.
  • It also has a programmable timer function to generate a reset signal if the input voltage does not return to a proper level within a specified time.
  • It has a very small package, SOT-23-8, making it ideal for space-constrained applications.


  • Battery-powered portable devices such as IoT sensors, wearables, and handheld instruments.
  • Industrial automation systems that require a reliable power supply.
  • Automotive electronics such as power management and battery monitoring.
  • Consumer electronics, including set-top boxes, digital cameras, and home appliances.
