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.

• 1.6V to 5.5V operating voltage

• 7.4µA supply current when /MR0, /MR1 not asserted

• 1.66V to 4.63V preset voltage threshold options

• 2.5% voltage threshold accuracy over temperature

• Asserting /MR0 and /MR1 for the setup delay time

asserts reset output for the reset timeout delay

• Programmable delay (PDY) input selects 2s, 4s or 6s

setup delay

• Factory-programmed 140ms (min.) or 240ms (min.)

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.

reset timeout delay

• Integrated /MR0, /MR1 pull-up resistors (MIC2786)

• Dual reset outputs:

− Open-drain, active-low reset output (/RST)

− Push-pull, active-high reset output (RSTP)

• −40°C to +85°C ambient operating temperature range

• 8-pin 2mm x 2mm x 0.55mm Thin MLF^®package

The MIC2786/MIC2787 consume a quiescent current of

only 7.4µA and are offered in a tiny, space saving 8-pin

Thin MLF^®(2mm x 2mm x 0.55mm) package.

Applications

• Smart phones

• Tablets

• Set-top boxes (STB)
