Features

  • Monitors two independent power supplies simultaneously
  • 3.09V fixed threshold for 3.3V rail monitoring
  • 0.3V adjustable reference for low-voltage rail monitoring
  • 140ms minimum reset timeout for stable system recovery
  • Manual reset input for external reset control
  • Ultra-low 3.5uA supply current extends battery life

Applications

  • Processor/FPGA core and I/O voltage monitoring
  • PDAs and handheld devices dual-rail supervision
  • Embedded controllers power-on reset generation
  • Telecommunications system voltage supervision
  • Wireless and cellular systems power management

The MIC2774N-31YM5 TR from Microchip Technology (formerly Micrel) is a dual micro-power voltage supervisor designed to monitor two independent power supply rails for undervoltage conditions. The N variant features an active-low open-drain reset output, with a fixed 3.09V threshold (ideal for 3.3V rails with 5% tolerance) and an adjustable input with a 0.3V reference (enabling monitoring of voltages as low as 0.3V). The device generates a minimum 140ms power-on reset pulse and includes a manual reset input. With only 3.5uA typical supply current, it is ideal for battery-powered applications. The YM5 suffix denotes SOT-23-5 package and TR indicates tape and reel packaging.

The MIC2774N-31YM5 TR operates as a dual power supply supervisor. (1) The fixed threshold comparator monitors the VDD pin against the factory-set 3.09V threshold with built-in hysteresis to prevent chattering on slow-rising supplies. When VDD drops below the threshold, the reset output is asserted. (2) The adjustable comparator compares the voltage at the ADJ pin against a precision 0.3V internal reference. An external resistor divider sets the desired threshold voltage, allowing monitoring of any rail down to 0.3V. (3) The 140ms minimum reset timeout is generated by an internal oscillator and counter, ensuring the processor has sufficient time to stabilize after power returns above the threshold. The manual reset input (/MR) allows an external switch or logic signal to assert reset independently of the voltage thresholds.
