Micro-Power Low Voltage Supervisor

Advance Information

General Description

Features

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-lowresetoutput. Theuser-adjustablemonitoringinput

is compared against a 300mV reference. This low reference

voltage allows monitoring voltages lower than those sup-

ported by previous supervisor ICs.

• User-adjustable input can monitor supplies as low as

0.3V

•

1.5% threshold accuracy

• Separate V input

• Generates power-on reset pulse (140ms min.)

• Manual reset input

• Choice of active-high, active-low or open-drain active-

low reset output

• Inputs can be pulled above V (7V abs. max.)

• Open-drain output can be pulled above V (7V abs.

The reset output is asserted for no less than 140ms 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. The reset output will remain

active at least 140ms 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 3.0µA.
