Product name: BD6393FP-E2

Application Field and Working Principle

BD6393FP-E2 is a Pulse-Width Modulated (PWM) motor drivers, controllers and power management integrated circuit (PMIC) from ROHM Semiconductors specifically designed for driving brushless DC motors. It includes a Hall amplifier, various protection functions and an integrated voltage regulator for obtaining motor speeds and temperatures within predetermined limits and for providing high-efficiency motor control.

The main function of the BD6393FP-E2 is to convert an input signal from the Hall effect Amplifier to an output signal that the motor can understand. This input signal is then converted to full bridge phase shifting outputs from the Hall amplifier and to a pulse-width-modulated (PWM) pulse output by the effective modulation circuit. With this modulation, the amount of power that goes to the motor is adjustable, which is how the BD6393FP-E2 can accurately control the speed of the motor.

In addition to the Hall amplifier and PWM outputs, the BD6393FP-E2 has several safety functions. These safety features include temperature monitoring, over-voltage protection, and soft-start. The device also features short-circuit output protection, EMF cancellation, and pulse blanking capability.

The BD6393FP-E2 is based on a unique technology ROHM calls “Hybrid Motor-Drive Architecture” (HMDA), which combines a high-efficiency synchronous rectifier with advanced PWM technology to achieve improved acceleration, high-speed operation, and low inductive noise. The HMDA also contributes to improved energy efficiency and lower overall system costs.

Overall, the BD6393FP-E2 provides a comprehensive solution for various motor applications and is ideal for brushless DC motor control applications. It can be used in medical devices, industrial equipment, or even home appliances requiring high accuracy motor control.
