PMICs, or Power Management Integrated Circuits, are commonly used in a wide range of applications, from home entertainment and office equipment to industrial automation and robotics. Motor drivers and controllers are especially useful in robotics and automation applications when controlling DC, stepper, and brushless motors. The DRV8313RHH is a dual-channel, brushless motor drive IC (Integrated Circuit) designed to reduce noise and simplify the control of high-current brushed and brushless DC motors.

The DRV8313RHH is a motor driver IC that can drive up to 28 A of peak current, tailored to applications with > 3 A/phase of peak current driving requirements. It contains two H-bridge output circuits integrated with a Gate Driver providing one-cycle current control for high-performance motor control. It also features low power dissipation, advanced protection features, and requires minimal external components for straightforward system design.

In terms of its application fields, the DRV8313RHH IC is suitable for direct current (DC) motor applications in consumer, industrial and automotive markets. Such applications can range from pumps, fans, and home appliances to 3-phase brushless DC motors with field-oriented control (FOC). It is also compatible with PWM (pulse width modulation) and Sine-wave current control methods. It can drive both brushed and brushless DC motors in applications such as:

• Power tools
• Electric scooters and bikes
• Power steering systems
• Industrial automation systems

Regarding its working principle, the DRV8313RHH is made up of an integrated driver for each of its two H-bridge output channels. The Gate Driver receives both PWM and CW/CCW logic signals from an external microcontroller and converts them into drive signals necessary to switch the outputs of the motor drivers that are connected to the external power transistor. The logic signals from the external microcontroller also control the operation of the motor drivers via phase-shift control and dead-time regulation.

Moreover, current limiting and short-circuit protection is enabled by the DRV8313RHH IC\'s integrated Gate Driver, and it also integrates a protection timer that shuts down the Gate Driver when a sustained over-current condition is detected. Its protect timer is designed to limit the duration of an over-current event and reset the Gate Driver once the fault has been cleared if the fault duration is shorter than the detect-time limit.

In addition, the DRV8313RHH supports the monitoring of temperature and current using an external temperature sensor and current-sensing resistor, respectively. On-chip diagnostics can be accessed by an external microcontroller so that it can monitor the status of the DRV8313RHH chip, shut down the driver if a fault condition is detected, and inform the host microcontroller of any faults. To make the system as reliable as possible, the DRV8313RHH provides comprehensive fault protection for both over-voltage and under-voltage conditions.

Overall, the DRV8313RHH is a robust motor driver IC that is suitable for applications where the control of high-current brushed and brushless DC motors is necessary. It is versatile enough to be used in a variety of consumer, industrial and automotive markets, with its support for both PWM and Sine-wave current control as well as integrated protection features ensuring its reliability.
