MIC2782

MIC2782 Dual-Input Push Button Reset IC with Immediate and Delayed Outputs General Description 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 × 1.2mm wafer level chip scale package. Data sheets and support documentation can be found on Micrel’s web site at: www.micrel.com.
