MIC2786/MIC2787
Push-Button Reset IC with Voltage
Supervisor
General Description
Features
The MIC2786/MIC2787 are low-current, ultra-small, push-
button supervisor reset ICs with an integrated supply
voltage monitor. The device features two manual reset
inputs and two reset outputs. The reset outputs are
asserted and held when the supply voltage decreases
below the factory programmed threshold voltage. Reset
will be asserted for the reset timeout delay once the supply
voltage increases above the rising threshold voltage or
when both manual reset inputs are asserted low for longer
than the setup delay time.
The MIC2786 features integrated pull-up resistors on the
/MR0 and /MR1 inputs, while the MIC2787 requires
external pull-up resistors. The PDY input pin selects
between a 2s, 4s or 6s setup period. Factory-programmed
reset timeout delays of 140ms (min.) and 240ms (min.) are
available. An active-low, open-drain reset output (/RST)
and an active-high, push-pull reset output (RSTP) provide
flexibility when interfacing to various microcontrollers,
PMICs, or load switches.
The MIC2786/MIC2787 consume a quiescent current of
