MIC2782

Dual-Input Push Button Reset IC

with Immediate and Delayed Outputs

General Description

Features

The MIC2782 is a two input, two output push-button reset

IC. It will generate a reset pulse for a factory-programmed

reset timeout period after both manual reset inputs have

been held to a logic-low for the factory-programmed setup

period. The MIC2782 also has an ANDOUT logic output

which will activate if both inputs are held low for longer

than a debounce time (1.5ms), and deactivate if one or

both inputs are released for longer than a debounce time

(1.5ms). The RESET and ANDOUT outputs are active-low,

open-drain NMOS outputs.

• 1.5V to 5.5V operating supply voltage range

• 2.2µA supply current with /MR1, /MR2 not asserted

• Factory-programmed setup periods of 6s, 8s, 10s or 12s

• Factory-programmed reset timeout periods of 0.5s, 1s or

• Integrated 65kΩ /MR1 and /MR2 pull-up resistors

• Supports single push-button reset with /MR1 tied to

/MR2

• RESET asserts after /MR1 and /MR2 are asserted low

The MIC2782 operates over the 1.5V to 5.5V supply

voltage range, consuming 2.2µA of supply current at 3.3V.

The device features 65kΩ internal pull-up resistors on both

of the inputs (/MR1 and /MR2). The device offers factory

programmed setup periods of 6s, 8s, 10s, or 12s and reset

timeout periods of 0.5s, 1s or 2s. It is available in a space

saving, 6-bump, 0.4mm pitch, 0.8mm × 1.2mm wafer level

chip scale package.
