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  
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.  
1.5V to 5.5V operating supply voltage range  
2.2µA supply current with /MR1, /MR2 not asserted  
Factory-programmed setup periods of 6s, 8s, 10s or 12s  
Factory-programmed reset timeout periods of 0.5s, 1s or  
2s  
Integrated 65k/MR1 and /MR2 pull-up resistors  
Supports single push-button reset with /MR1 tied to  
/MR2  
RESET asserts after /MR1 and /MR2 are asserted low  
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 65kinternal 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.
