PMIC (Power Management Integrated Circuit) is an integral part of any modern electronic device. It is responsible for managing the power supply of the device. Power management ICs help in optimizing the power utilization within the system. DRV8828PWPR is a dual motor driver IC from Texas Instruments, which is designed to drive two DC motors. It comes with a full bridge integrated power stage and offers an efficient bridge for bidirectional current control.
The DRV8828PWPR is mainly used in applications such as toys, automotive control systems, robots, and household appliances. This device allows the user to easily configure the speed, direction, and current control of the motors. With its integrated full bridge power stage, it is able to supply a peak current of 5A per bridge. The device also comes with thermal protection and the ability to short circuit. It can handle a variety of input power supplies ranging from 12V to 44V.
Working Principle:
The DRV8828PWPR is a two-channel, two-phase, full-bridge PWM (pulse width modulation) motor driver that follows current-mode PWM control. It uses N-channel MOSFETs to provide bidirectional drive currents up to 5A (peak). The power MOSFETs can be forced off at any time, allowing for quick current shutdown to protect the motor.
The IC has two logic inputs - one for controlling the speed and direction of a motor, and another to enable or disable the IC. Inputs are used to control the two PWM outputs which are used to control the two full bridges. By connecting two independent motors to the two bridges, two separate sets of speed and direction control can be achieved. The PWM output signals are switched on and off at a frequency of up to 2 MHz, which provides a high resolution control of the motor speed.
The DRV8828PWPR also offers current sensing capabilities with its integrated voltage divider. The voltage divider senses the motor current via the small-signal LED pins and uses this information to provide an internal current limit for protection. It also has an internal over-current flag, which indicates when the peak current limit is exceeded.
The DRV8828PWPR also offers programmable deadtime control. The deadtime is the time when the PWM signal is switched off, allowing the load to be free for a short period of time. This provides a smooth, low ripple drive and helps reduce the amount of heating in the system. Additionally, the device has an internal temperature sensor and thermal protection circuit, which can detect when the device is operating at high temperatures and shut down the system.
The DRV8828PWPR is suitable for a variety of applications, including DC motors, camera servos, robotic arms and legs, and medical pumps. It is an easy to use, cost-effective solution for driving two DC motors in an efficient and safe manner.
