MIC2785  
Dual Supply Voltage Monitor  
with Manual Reset  
General Description  
Features  
The MIC2785 is a micropower voltage monitor that  
provides undervoltage monitoring and manual reset  
capability in a tiny 1.2mm × 1.2mm QFN package. The  
MIC2785 provides a monitored voltage input (VIN) separate  
from the supply input (VDD). This insures that the reset  
(/RST) output maintains a valid output state when the  
voltage being monitored ramps up or down. The device  
also includes a manual reset input (/MR). The /RST output  
is an active low push-pull output.  
No external components  
Monitors input voltage for under-voltage condition  
Separate inputs for supply (VDD) and monitor (VIN)  
+1.5% VIN threshold voltage accuracy  
Valid /RST state with VIN down to 0.0V  
Valid /RST state with VDD down to 1.20V  
Factory-programmed 1.62V reference  
Manual reset input (/MR)  
The undervoltage detector compares the VIN pin voltage  
against the factory-programmed threshold of 1.62V. The  
reset output is asserted any time the input voltage drops  
below the programmed threshold voltage. A reset can be  
generated at any time by asserting the manual reset input,  
/MR. This reset output will remain active until the release  
of /MR. The /MR input can also be used to daisy-chain the  
MIC2785 onto existing power monitoring circuitry or other  
supervisors. Hysteresis is included to prevent chattering  
due to noise.  
Active low RESET (/RST) output  
Ultra-low input current – 5µA total (VIN and VDD)  
Rejects brief input transients  
–40°C to 85°C operating temperature range  
RoHS lead-free compliant  
Available in 6-pin 1.2mm × 1.2mm Thin QFN package  
Applications  
Mobile phones  
PDAs  
GPS Receivers  
The MIC2785 consumes a minimum of quiescent current,  
only 5µA, 1.5µA from the main supply pin and 3.5µA from  
the input pin. Offered in a tiny space saving 6-pin QFN  
1.2mm × 1.2mm package.
