MCP111/112  
Micropower Voltage Detector  
Features  
Description  
• Ultra low supply current: 1.75 µA (max.)  
The MCP111/112 are voltage-detecting devices  
designed to keep a microcontroller in reset until the  
system voltage has reached and stabilized at the  
proper level for reliable system operation. These  
devices also operate as protection from brown-out  
conditions when the system supply voltage drops  
below a safe operating level. The MCP111 and  
MCP112 are available in eight different trip voltages.  
Precision monitoring options of:  
- 1.90V, 2.32V, 2.63V, 2.90V, 2.93V, 3.08V,  
4.38V and 4.63V  
• Resets microcontroller in a power loss event  
• Active-low VOUT pin:  
- MCP111 active-low, open-drain  
- MCP112 active-low, push-pull  
The MCP111 has an open-drain output with an active-  
low pin (VOUT). This device will assert VOUT when the  
voltage on the VDD pin is below the trip-point voltage.  
• Available in SOT23-3, TO-92 and SC70 packages  
Temperature Range:  
- Extended: -40°C to +125°C  
(except MCP1XX-195)  
The MCP112 has a push-pull output and will assert an  
active-low signal (VOUT pin) when the voltage on the  
VDD pin is below the trip-point voltage.  
- Industrial: -40°C to +85°C (MCP1XX-195 only)  
During operation, the output (VOUT) remains at a logic-  
high as long as VDD is greater that the specified  
threshold voltage. When VDD falls below the voltage  
trip point, VOUT is driven low.  
Applications  
• Critical µC and µP Power Monitoring Applications  
• Computers  
• Intelligent Instruments  
Package Types  
SOT23-3/SC-70
