Microprocessor Power Supervisory for Pager
การออกแบบอ้างอิง โดย: Analog Devices
Receiving infrared (IR) signals while conserving system power is difficult, and typically requires the inclusion of complex power-management routines in the firmware. You can avoid that problem by disconnecting power to the microcontroller when IR is not present. The resulting circuit draws less than 2uA of supply current while in standby mode, and approximately 40uA when active
