MIC2782 Dual-Input Push Button Reset IC with Immediate and Delayed Outputs General Description Features The MIC2782 is a two input, two output push button reset 1.5V to 5.5V Operating Supply Voltage Range IC. It will generate a reset pulse for a factory programmed 2.2 A Supply Current with /MR1, /MR2 not asserted reset timeout period after both manual reset inputs have Factory programmed setup periods of 6s, 8s, 10s or 12s been held to a logic-low for the factory programmed setup Factory programmed reset timeout periods of 0.5s, 1s or period. The MIC2782 also has an ANDOUT logic output 2s which will activate if both inputs are held low for longer than a debounce time (1.5ms), and deactivate if one or Integrated 65k /MR1 and /MR2 Pull-Up Resistors both inputs are released for longer than a debounce time Supports single push button reset with /MR1 tied to (1.5ms). The RESET and ANDOUT outputs are active-low, /MR2 open-drain NMOS outputs. RESET asserts after /MR1 and /MR2 are asserted low The MIC2782 operates over the 1.5V to 5.5V supply for a setup period voltage range, consuming 2.2 A of supply current at 3.3V. ANDOUT asserts after /MR1 and /MR2 are asserted low The device features 65k internal pull-up resistors on both for a debounce time (1.5ms) of the inputs (/MR1 and /MR2). The device offers factory Open-Drain RESET and ANDOUT Outputs programmed setup periods of 6s, 8s, 10s, or 12s and reset 6-bump, 0.4mm pitch, 0.8mm x 1.2mm Wafer Level timeout periods of 0.5s, 1s or 2s. It is available in a space Chip Scale Package (WLCSP) saving, 6-bump, 0.4mm pitch, 0.8mm x 1.2mm Wafer Level Chip Scale Package.
