Over-discharge protection: in between the P + and P- connected load to the battery discharge when the battery voltage drops to over-discharge voltage (2.35 * 2 ± 0.01), the protection circuit, shut off the discharge path to achieve the over-discharge protection. Short circuit protection: When the P + and P- short-circuit protection circuit will quickly moving within 5-50uS, cut off access, short-circuit protection. Over-current protection: When the V- terminal voltage of (0.15 ± 0.02V), the protection circuit will quickly moving within 5-26ms, to cut off access, overcurrent protection. Temperature: -20 / + 60 (℃) Applications: all kinds of electronic products, lighting lamps, mobile products, digital products, IT products, instrumentation, IC card terminals, medical equipment, etc. 1.
