The DRV8307RHAR is a pulse width modulation (PWM) controller designed for driving brushless DC motors in automotive applications. The DRV8307RHAR is a flexible IC that can be used in a variety of applications from small BLDC motors to large 3-phase industrial motor control applications. The DRV8307RHAR has a wide input voltage range, robust protection and diagnostic features, and low external component count.The DRV8307RHAR has a high system efficiency and integrates a dual-channel full-bridge driver and a voltage regulator. The high-speed full-bridge PWM outputs can be programmed to generate a 12-bit resolution sine wave drive signal with up to 32-kHz frequency. The PWM outputs are capable of driving 5-A to 15-A peak gate current with up to 28-V gate voltage. The device also features a low on-resistance integrated power switch with overcurrent protection, and an optional integrated 200-V boot board regulator for an extended voltage range.The DRV8307RHAR is designed for use with 3-phase brushless DC motors, and can be used in various applications such as automotive alternators, power steering, and power window motors. The device is also suitable for other applications such as small DC motors, brushless fans, and pumps. The device is also designed with robust and protective features such as overcurrent and over-temperature protection and fault diagnostics.DRV8307RHAR has five electrical operating states: High-Side Precharge, Standby, Turn-On, Run, and Turn-Off. In the High-Side Precharge state, the internal bootstrap buck regulator turns on to precharge the high-side gate capacitors to the VDDIO rail voltage. In Standby, the low-side FETs are off while the high-side FETs remain in precharge mode. The Turn-On state sequences the high-side drivers to turn on the high-side FETs, followed by the low-side FETs. In the Run state, the PWM outputs are enabled to generate the sine wave control signal for maximum efficiency. Finally, in the Turn-Off state, the low-side FETs are turned off, followed by the high-side FETs to disable the motor current. The DRV8307RHAR also has a wide range of fault diagnostics and protections that can be monitored by an external microcontroller. These fault conditions include, but are not limited to, undervoltage lockouts, overcurrent detection, overvoltage detection, over-temperature, and short-to-battery. The microcontroller can then use this information to safely shut down or reset the device, depending on the error code sent.In summary, the DRV8307RHAR is a powerful PWM controller designed for driving brushless DC motors in a wide variety of applications. It has a wide input voltage range, integrated dual-channel full-bridge driver, and low external components count. The device also features robust and protective features such as overcurrent protection, over-temperature protection, and fault diagnostics. The DRV8307RHAR is a great choice for automotive applications, small DC motors, brushless fans and pumps, and various other industrial motor control applications.
