CM1270 series 6~7 series rechargeable lithium battery protection IC (for level 2 protection)
CM1261 series products have built-in high-precision voltage detection circuit and delay circuit. It is a secondary protection chip for rechargeable battery packs. By detecting the voltage of each cell in the battery pack, it provides overcharge protection and protection for the battery pack. Over discharge protection.
Features:
1) High-precision battery voltage detection function: ?
Overcharge detection voltage 3.50 V ~ 4.50 V (50 mV step) Accuracy ±25 mV ?
Overcharge recovery voltage 0~0.55V (step 50mV) Accuracy ±50 mV ?
Overdischarge detection voltage 2.00 V ~ 3.20 V (100 mV step) Accuracy ±80 mV ?
Overdischarge recovery voltage 0 V ~ 0.5 V (100 mV step) Accuracy ±100 mV
