Features & Applications
The MIC2775 is a 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 an under-voltage detector, a delay generator, a manual reset input, and both active-high and active-low reset outputs. The under-voltage detector compares VDD against a fixed threshold. Ten factory-programmed thresholds are available.

The reset outputs are asserted for no less than 140 ms at power-on and any time the input voltage drops below the reference voltage. It remains asserted for the timeout period after the input voltage subsequently rises back above the threshold boundary. A reset can be generated at any time by asserting the manual reset input, /MR. This reset output will remain active at least 140 ms after the release of /MR. The /MR input can also be used to daisy-chain the MIC2775 onto existing power monitoring circuitry or other supervisors. Hysteresis is included to prevent chattering due to noise. Typical supply current is a low 3.5 µA.

Features :

  • Monitors power supply for under-voltage conditions
  • Choice of factory-programmed thresholds
  • Generates 140 ms (minimum) power-on RESET pulse
  • Manual reset capability
  • Both active-high and active-low RESET outputs
  • /RST output valid down to 1.2 V
  • Ultra-low supply current, 3.5 µA typical
  • Rejects brief input transients
  • No external components
  • Pin compatible upgrade for MAX825
  • IttyBitty™ 5-lead SOT-23 package

Applications :

  • Monitoring processor core and input/output voltages
  • Computer systems
  • PDAs, hand-held PCs
  • Embedded controllers
  • Telecommunications systems
  • Power supplies
