LT1381CS General Description

LT1381CS is a voltage comparator IC (integrated circuit) manufactured by Linear Technology (now part of Analog Devices). It is a low-power, high-speed device designed for precision voltage detection and monitoring in a wide range of applications.



  • Wide input voltage range: The device can operate with input voltages ranging from 2.5V to 36V, making it suitable for use in a variety of power supply and battery-operated systems.
  • High speed: The LT1381CS is a fast comparator, with a propagation delay of only 9ns and a response time of 25ns.
  • Low power consumption: The device has a low quiescent current of 45µA, making it ideal for battery-powered applications.
  • Adjustable hysteresis: The LT1381CS features an adjustable hysteresis, allowing the user to set the threshold voltage and adjust the trip point to avoid false triggering.
  • Wide temperature range: The device can operate over a temperature range of -40°C to 85°C, making it suitable for use in harsh environments.


  • Voltage monitoring and detection: The device can be used to monitor battery voltage levels, supply voltage levels, and other critical voltage levels in a variety of systems.
  • Overvoltage and undervoltage protection: The LT1381CS can be used to protect sensitive components from damage due to overvoltage or undervoltage conditions.
  • Power supply sequencing: The device can be used to sequence the turn-on and turn-off of power supplies in complex systems.
  • Switching power supply control: The LT1381CS can be used to control the output of a switching power supply, ensuring stable operation and preventing damage to the load.
