Would you be so kind to point out any errors in this schematic or anything else to improve (layout and clarity also greatly appreciated).
This is supposed to be the power/regulating/batterycutoff schematic of a device.
- Device has a lipo battery and a switch (S1) to turn on and off.
- Battery is connected to voltage detector (U3) which sends a high
signal to U4 at 3.05V.
- Battery also connected to analog switch (U4). Depending on signal from U3
switches between battery low warning led and main circuit. (acts like relay)
- U2 regulates power supply to 2.8V (VCC) which supplies main circuit .
