1. The application of self recovery fuse in rechargeable battery pack

1) Problem and Analysis: NICD, NiMH, and Li-ION are commonly used in special protection circuits for mobile phones and computers. The reasons for these battery pack failures are usually: an unexpected short circuit between the positive and negative terminals; The charger cannot stop charging a fully charged battery; The polarity of the wrong charger or the battery is reversed. Installing the PTC patch series in series in various units of the battery pack can provide overcurrent and over-temperature protection for the circuit.

2) Protection requirements: In the event of a malfunction, the voltage of the mobile phone can reach 16V, and the voltage of the computer can reach 24V; Its current can reach 100 amperes. In overcharging conditions, the battery pack needs to be protected against overheating. NiCD batteries cannot eXCeed 120C, and NiMH and Li-Ion batteries cannot exceed 90C.

The ultra-small package (0402 specifications) is very suitable for secondary protection of circuits and is suitable for applications with limited space, such as handheld portable electronic devices.
