Microchip's 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 (1.5 ms), and deactivate if one or both inputs are released for longer than a debounce time (1.5 ms). The RESET and ANDOUT outputs are active-low, open-drain NMOS outputs.
The MIC2782 operates over the 1.5 V to 5.5 V supply voltage range, consuming 2.2 mA of supply current at 3.3 V. The device features 65 kΩ internal pull-up resistors on both of the inputs (/MR1 and /MR2). The device offers factory programmed setup periods of 6 s, 8 s, 10 s, or 12 s and reset timeout periods of 0.5 s, 1 s or 2 s. It is available in a space saving, 6-bump, 0.4 mm pitch, 0.8 mm x 1.2 mm wafer level chip scale package.
