MIC2782FRYCS-TR [Microchip]

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 2.2µA 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 x 1.2mm Wafer Level Chip Scale Package.
