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.
The MIC2782 operates over the 1.5V to 5.5V supply
voltage range, consuming 2.2ВµA 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 Г— 1.2mm wafer level
chip scale package.
