简介
RAA306012 是一款适用于 3 相无刷直流 (BLDC) 电机应用的智能MOSFET 栅极驱动器。 RAA306012 集成了三个半桥栅极驱动器，这些驱动器能够驱动多达 3 个 N沟道 MOSFET 桥，且支持 6V 至 65V 的桥电压。 每个栅极驱动器支持高达 0.64A 的拉电流及 1.28A 灌电流的峰值驱动电流，并具备可调节的驱动强度控制。 自适应且可调节的死区时间设计可确保产品兼具稳健性与灵活性。 主动栅极保持机制能够避免米勒效应引起的交叉传导现象，进一步增强了产品的稳健性。
该设备集成了为内部模拟及逻辑电路、高压侧/低压侧栅极驱动器供电的电源，以及专为外部控制器供电的电源。 RAA306012 还具备低功耗休眠模式。该模式的功耗仅为 28μA，能够最大限度地延长便携式应用中电池的使用时间。
