Microchip MIC2782 Dual-Input Push Button Reset ICs with immediate and_delayed outputs 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 ANDOUT logic output of these two input, two output push button reset ICs 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. MIC2782 operates in the 1.5V to 5.5V supply voltage range, consuming 2.2µA of supply current at 3.3V. These devices feature 65kΩ internal pull-up resistors on both of the inputs (/MR1 and_/MR2). Offering factory-programmed setup periods of 6s, 8s, 10s, or 12s and_reset timeout periods of 0.5s, 1s, or 2s, MIC2782 is available in a space-saving, 6-bump, 0.4mm pitch, 0.8mm x 1.2mm Wafer Level Chip Scale Package.
