摘要： MOSFET功率开关驱动器必须从电池反向连接保护。一个小的整流二极管可以防止逆转的电池，但这种做法是不可接受的一般系统中，电池的寿命是至关重要的。二极管的正向压降（ 0.6V至0.7V典型值）为6V电池，产生了约10％的恒功率的损失，这与日益减少的电池电压增加。比单二极管保护的改进。Maxim > App Notes > BATTERY MANAGEMENT POWER-SUPPLY CIRCUITS Keywords: MOSFET driver, reverse battery protection, mosfet, reverse battery protected, power switch May 11, 2003 drivers, diode protection APPLICATION NOTE 2012 MOSFET Driver Is Reverse-Battery Protected Abstract: MOSFET power-switch drivers must be protected from a reverse-battery connection. A small rectifier diode can protect against reversed batteries, but that approach is generally unacceptable for systems in which battery life is crucial. For a 6V battery, the diode's forward voltage drop (0.6V to 0.7V typical) produces a constant power loss of approximately 10%, which increases with dwindling battery voltage. An improvement over single-diode protection is shown. MOSFET power-switch drivers must be protected……
