Precision Voltage Supervisor IC with Open-Drain Reset Output for Reliable Microcontroller Power Monitoring

The TPS3803-01DCKR is a compact voltage supervisor designed to monitor system power rails and ensure reliable operation of microcontrollers and digital circuits. Developed by Texas Instruments, this device detects undervoltage conditions and asserts a reset signal to prevent system malfunction during power fluctuations or unstable supply conditions.

The device features an open-drain reset output, allowing flexible interfacing with different logic voltage levels through an external pull-up resistor. With its precise threshold detection and built-in reset delay timer, the TPS3803-01DCKR ensures stable system startup and reliable operation during power-up and power-down events. Its ultra-small SC-70-5 package makes it ideal for compact embedded systems, portable electronics, industrial controllers, and IoT devices where board space and power reliability are critical.

Key Features

  • Precision Voltage Supervisor: Monitors supply voltage and detects undervoltage conditions.
  • Open-Drain Reset Output: Flexible interfacing with microcontroller reset pins.
  • Automatic Power-On Reset: Ensures proper system startup after voltage stabilisation.
  • Integrated Reset Delay: Provides controlled reset release for stable operation.
  • Single Power Rail Monitoring: Designed for reliable supervision of one supply line.
  • Low Power Consumption: Suitable for battery-powered electronics.
  • Fast Response to Voltage Drops: Protects system operation during power instability.
  • Compact SC-70 Package: Ideal for space-constrained PCB designs.
