Power Management ICs (PMICs) are a critical component of most electronic devices in the market today. One such PMIC is the DRV8842PWPR, a dual-channel H-bridge motor driver IC capable of operating at a relatively high current of up to 9 A continuous, peak current of 18 A. This device enables direct-drive control of stepper/brushless DC (BLDC) as well as RS485/RS232-controlled applications on multiple motor types such as piezo, voice coil, brushed DC and stepper.
The DRV8842PWPR is well suited for a variety of applications including speed control, current control and position control solutions. This device features a wide operating voltage range of 8 V to 45 V for both logic supply and motor supply, enabling it to be used in a wide variety of applications. Its pulse width modulated (PWM) input allows for up to 256 PWM resolution, making it ideal for speed and position control applications. Additionally, the DRV8842PWPR offers short circuit protection, overcurrent protection and thermal protection.
The DRV8842PWPR\'s working principle is based on its ability to generate two independent output channels between 0 V and the voltage of the motor supply. These two channels are used to drive two separate channels for stepper/BLDC or brushless DC motors. By applying voltage to each of these channels, the DRV8842PWPR can generate a full H-bridge circuit on the motor, enabling bidirectional control of the motor by varying the voltage across these channels. In the case of speed or position applications, the DRV8842PWPR can be used to produce a PWM signal which is then used to control the speed or position of the motor.
The DRV8842 is also well suited for applications requiring current feedback. The DRV8842\'s current sense feature allows the output current to be monitored continuously to ensure that the motor is running at the desired speed or position. This feature can be used in high-current applications where a current sensor is unable to be used. Additionally, the DRV8842 is capable of generating a Voltage Difference Location (VDL) output. This output will change its value depending on the direction of current being monitored. This feature is useful for controlling the travel direction of a stepper or BLDC motor.
In conclusion, the DRV8842PWPR is an ideal choice for high-current motor control applications. Its wide operating voltage range, PWM control and current sense features, make the DRV8842PWPR a versatile solution for stepper/BLDC motor control applications. Additionally, its Voltage Difference Location output is a useful feature for controlling the direction of the motor during operation. This makes the DRV8842PWPR an excellent choice for a wide range of motor control applications.
