Datasheet

Microprocessor Voltage Supervisor IC with 2.9V Reset Threshold and Manual Reset for Embedded Systems

The APX811-29UG-7 is a compact microprocessor supervisor designed to monitor system supply voltage and provide reliable reset control for microcontrollers and processor-based systems. Manufactured by Diodes Incorporated, this device continuously supervises the VCC supply and generates a reset signal whenever the supply voltage drops below a predefined threshold, protecting the system from unstable power conditions.

The device includes a push-pull active-low RESET output and an integrated manual reset (MR) input that allows external reset triggering when required. When the supply voltage recovers above the reset threshold, an internal timer maintains the reset signal for at least 240 ms to allow sufficient time for the processor and peripherals to stabilise before normal operation resumes. The APX811-29UG-7 is well suited for embedded systems, communication devices, industrial controllers, and portable electronics requiring reliable power supervision.

Key Features

  • Microprocessor Voltage Supervisor: Monitors system supply voltage and triggers reset during undervoltage conditions.
  • Active-Low Push-Pull RESET Output: Direct interface with microcontroller reset pins.
  • Manual Reset Input (MR): Enables external reset control when needed.
  • Internal Reset Delay: Holds reset active for at least 240 ms after voltage recovery.
  • 2.9V Reset Threshold: Suitable for 3V and 3.3V powered systems.
  • Reliable Power-On Reset: Ensures stable system startup during power-up.
  • Compact SOT-143 Package: Small footprint suitable for dense PCB layouts.
  • Industrial Temperature Range: Operates from −40 C to+85 C.
