Features & Applications

The MIC2774N-44YM5 TR is a part of MIC2774 series dual power supply supervisor that provides under-voltage monitoring, manual reset capability, and power-on reset generation in a compact 5-pin SOT package.

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. Ten factory-programmed thresholds are available. 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.

Features :

  • Monitors two independent power supplies for under-voltage conditions
  • One fixed and one user adjustable input
  • Choice of factory-programmed thresholds
  • Adjustable input can monitor supplies as low as 0.3V
  • Generates 140ms (minimum) power-on reset pulse
  • Manual reset input
  • Choice of active-high, active-low, or open-drain active-low reset outputs
  • Inputs may be pulled above VDD (7V abs. max.)
  • Open-drain output can be pulled above VDD (7V abs max.)
  • /RST output valid down to 1.2V
  • Ultra-low supply current, 3.5µA typical
  • Rejects brief input transients
  • IttyBitty™ 5-lead SOT-23 package
  • Pin compatible upgrade for MAX6306/09/12


  • Monitoring processor ASIC, or FAGA core and I/O voltages
  • PDAs, hand-held PCs
  • Embedded controllers
  • Telecommunications systems
  • Power supplies
  • Wireless / Cellular systems
  • Networking hardware
