MIC2775  
Micro-Power Voltage Supervisor  
IttyBitty®  
General Description  
Features  
The MIC2775 is a power supply supervisor that provides  
undervoltage monitoring, manual reset capability, and  
power-on reset generation in a compact 5-pin SOT  
package. Features include an undervoltage detector, a  
delay generator, a manual reset input, and both active-  
high and active-low reset outputs. The undervoltage  
detector compares VDD against a fixed threshold. Ten  
factory-programmed thresholds are available.  
Monitors power supply for undervoltage conditions  
Choice of factory-programmed thresholds  
Generates 140ms (minimum) power-on reset pulse  
Manual reset capability  
Both active-high and active-low reset outputs  
/RST output valid down to 1.2V  
Ultra-low supply current, 3.5µA typical  
Rejects brief input transients  
No external components  
The reset outputs are asserted for no less than 140ms at  
power-on and any time the input voltage drops below the  
reference voltage. It remains asserted for the timeout  
period after the input voltage subsequently rises back  
above the threshold boundary. A reset can be generated  
at any time by asserting the manual reset input, /MR. This  
reset output will remain active at least 140ms after the  
release of /MR. The /MR input can also be used to daisy-  
chain the MIC2775 onto existing power monitoring circuitry  
or other supervisors. Hysteresis is included to prevent  
chattering due to noise. Typical suppy current is an ultra-  
low 3.5µA.
