DRV8307 是一款三半桥前置驱动器，此驱动器用一个单电源驱动6 个N 类型MOSFET 30mA 。针对传感三相无刷直流电机，DRV3807 由单个PWM 输入驱动，并且支持具有三个霍尔传感器输入的集成换相逻辑电路。还包括一个为霍尔效应传感器和其他外部组件供电的独立5V 稳压器。

DRV8307 包括一个用于限流和保护的电流感测输入。可以通过调节RISENSE 感测电阻器的值来设定电流限值。

通过ENABLEn 端子来控制电机运行（启动和停止）。如果ENABLEn 端子被置为高电平，并且电机停止旋转，此器件进入低功率待机状态，从而在静止期间节省总体系统功耗。

在DRV8307 中还包括诸如锁定转子检测、过流和过热保护，以及欠压闭锁等保护特性，以便为整体系统稳定耐用性和可靠性提供保证。

The DRV8307 device controls 3-phase brushless DC motors using a speed and direction input interface and Hall signals from the motor. The device drives N-channel MOSFETs with 10-V VGS and a gate drive current of 30 mA.

The speed of the motor is controlled by varying the duty cycle of the input clock (pulse-width modulation). Motor speed is indicated on the HALLOUT terminal, which follows the HALL U transitions.

When the DRV8307 device begins spinning a motor, it initially uses all three Hall sensor phases to commutate. After a constant speed is reached, the LOCKn terminal is pulled low and only one Hall sensor becomes used; this feature reduces jitter by eliminating the error caused by non-ideal Hall device placement and matching.

Numerous protection circuits prevent system components from being damaged during adverse conditions. Monitored aspects include motor voltage and current, gate drive voltage and current, device temperature, and rotor lockup. When a fault occurs, the DRV8307 device stops driving and pulls FAULTn low, in order to prevent FET damage and motor overheating.

The DRV8307 device is packaged in a compact 6×6 mm, 40-terminal VQFN with a 0.5 mm terminal pitch, and operates through an industrial ambient temperature range of -40°C to 85°C.
