Features & Applications
The MIC2776 is a power supply supervisor which provides under-voltage monitoring and power-on reset generation in a compact 5-pin SOT package. Features include an adjustable under voltage detector, a delay-generator, a manual reset input, and a choice of active-high, active low, or open-drain active-low reset output. The user-adjustable monitoring input is compared against a 300 mV reference. This low reference voltage allows monitoring voltages lower than those supported by previous supervisor ICs.

The reset output is asserted for no less than 140 ms at poweron 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. The 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 MIC2776 onto existing power monitoring circuitry or other supervisors. Hysteresis is included to prevent chattering due to noise. Typical supply current is a low 3.0 μA.

Features :

  • User-adjustable input can monitor supplies as low as 0.3 V
  • ±1.5% threshold accuracy
  • Separate VDD input
  • Generates power-on reset pulse (140 ms min.)
  • Manual reset input
  • Choice of active-high, active-low or open-drain activelow reset output
  • Inputs can be pulled above VDD (7 V abs. max.)
  • Open-drain output can be pulled above VDD (7 V abs. max.)
  • Ultra-low supply current, 3.0 μA typical
  • Rejects brief input transients
  • IttyBitty™ SOT-23-5 package

Applications :

  • Monitoring processor, ASIC, or FPGA core voltage
  • Computer systems
  • PDAs/Hand-held PCs
  • Embedded controllers
  • Telecommunications systems
  • Power supplies
  • Wireless / cellular systems
  • Networking hardware
