0805 sized resistors & caps.
Requires that the positions marked 7135-A and 7135-B have at least one 7135 populated each. Requires that the 7135 next to R2 be populated for the voltage divider to work (eg LVP).
Single-cell component list:
- R1 - 22k 1% resistor
- R2 - 4.7k 1% resistor
- C1 - 5uF/10uF/whatever capacitor
- OTC - 1uF capacitor
- D1 - low Vf diode for polarity protection
Zener components:
- R1 - appropriate 1% resistor
- R2 - 4.7k 1% resistor
- C1 - 5uF/10uF/whatever capacitor
- OTC - 1uF capacitor
- R3 - appropriate 0805 resistor, such as 200 ohm
- Zener - appropriate SOD-123 zener, such as 4.3v
