General Description  
Band Gap  
Reference  
The MCP102/103/121/131 are voltage supervisor  
devices designed to keep a microcontroller in reset  
until the system voltage has reached and stabilized at  
the proper level for reliable system operation. Table 1  
shows the available features for these devices.
