Designing an Automatic Battery Cutoff Circuit to Prevent Over Discharge of Rechargeable Batteries Part 1

In this video we will design an automatic battery cutoff circuit to prevent damaging over discharge of rechargeable batteries. To design our battery cutoff circuit we will use a Voltage Detector or Reset IC.


BOM from video:

  • S-1011A70-M6T1U4 Voltage Detector from ABLIC 
  • DMP4015SSS-13 P Chan MOSFET from Diodes Inc 
  • BSS138 N Chan MOSFET from multiple manufacturers 
  • RSX051VYM30FHTR Schottky Diode from ROHM Semi 
  • 2x 3.3 nF Ceramic Capacitor 
  • ~100 kOhm Resistor 
  • 1 to 10 MOhm Resistor
