This circuit allows standard, enhancement-mode, NMOS FETs to operate from battery voltages as low as 3.5V. Because the charge pump runs on the battery voltage and thus also needs protection from battery reversal, the circuit connects a diode between the battery's positive terminal and the IC's V CC terminal.

今天和大家一起来学习下常见的车载电子防反接电路。 01 Why Reverse Battery Protection?想象一下下面这个场景，车子好久没开了，电池馈电打不起火了。这时候好心的邻居帮你搭电。邻里之间有说有笑，多么和谐的景…

With reverse applied voltage, a short circuit via diodes or transistors could occur, leading to fatal errors of the electronics of the car. This means, that the ECUs (Electronic Control Unit) have to be protected against reverse battery polarity. In this chapter three most common reverse battery protection circuits will be discussed.

2017年6月10日 · Reverse battery current protection using LTC4359 integrated circuit. The LTC®4359 is a positive high voltage, ideal diode controller that drives an external N-channel MOSFET to replace a Schottky diode. It controls the forward-voltage drop across the MOSFET to ensure smooth current delivery without oscillation even at light loads.

Users of battery powered equipment expect safeguards to prevent damage to the internal electronics in the event of reverse battery installation, accidental short circuiting, or other inappropriate operation. These safeguards can be either mechanical or electronic.
