Product Overview

The MIC2774N-44YM5 TR is a dual Power Supply Supervisor provides under-voltage monitoring, manual reset capability and power-on reset generation. Features include two under-voltage detectors, one fixed and one adjustable and a choice of reset outputs. One under-voltage detector compares VDD against a fixed threshold. The second, user-adjustable input is compared against a 300mV reference. This low reference voltage allows monitoring voltages lower than those supported by previous supervisor ICs. The reset outputs are asserted at power-on and any time either voltage drops below the programmed threshold voltages and remains asserted for 140ms (minimum) after they subsequently rise back above the threshold boundaries. Manual reset functionality can be provided by a switch connected between ground and the MR input. Hysteresis is included to prevent chattering due to noise. Typical supply current is a low 3.5µA.
  • Monitors two independent power supplies for under-voltage conditions
  • One fixed and one user adjustable input
  • Generates 140ms (minimum) power-ON reset pulse
  • Manual reset input
  • Rejects brief input transients
  • Adjustable input can monitor supplies as low as 0.3V
  • Inputs may be pulled above VDD (7V absolute maximum)
  • Open-drain output can be pulled above VDD (7V absolute maximum)
  • /RST output valid down to 1.2V
  • Pin-compatible upgrade for MAX6306/09/12
  • 3.5µA Typical ultra-low supply current
