Microchip Technology MIC2782 Dual-Input Push Button Reset ICs

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.
