FROM PIC
For applications that can operate directly from the battery input voltage during Sleep mode and
require a higher voltage during normal run mode, the MCP1640C device provides input to output
bypass when disabled. The PIC Microcontroller is powered by the output of the MCP1640C. One
of its I/O pins is used to enable and disable the MCP1640C to control its bias voltage. While
operating in Sleep mode, the MCP1640C input quiescent current is typically less than 1 uA.
