电池逆转，可以是致命的便携式设备。然而，无数电路可以防止向后安装电池和其他造成过流条件。Maxim > App Notes > BATTERY MANAGEMENT POWER-SUPPLY CIRCUITS Keywords: Reverse-Current Circuitry Protection Jan 31, 2001 APPLICATION NOTE 636 Reverse-Current Circuitry Protection Battery reversal can be fatal to portable equipment. However, numerous circuits can protect against the backward installation of batteries and other overcurrent-causing conditions. Battery-operated equipment is prone to the consequences of batteries installed backward, accidental short circuits, and other types of careless use. The effects of a reversed battery are critical. Unfortunately, it is difficult to guard against this situation. To make equipment resistant to batteries installed backward, you must design either a mechanical block to ……
