Overview
The DRV8812PWP is a dual-bridge motor controller IC manufactured by Texas Instruments, designed for driving bipolar stepper motors and brushed DC motors. It integrates control logic and power stages within a single package. The device supports a supply voltage range of 8.2V to 45V and delivers an output current of 1.6A per bridge. It utilizes Power MOSFET technology and features a parallel interface for command input. The component is housed in a 28-PowerTSSOP (HTSSOP) surface-mount package with a width of 4.40mm. It operates reliably across a junction temperature range of -40°C to 150°C.
Feature Summary
- Integrates four half-bridge outputs to drive two bipolar stepper motors or one brushed DC motor
- Supports high-voltage operation up to 45V with integrated power MOSFETs
- Features a parallel interface for straightforward digital control signals
- Includes thermal shutdown protection for enhanced reliability
Applications
- Bipolar stepper motor control systems
- Brushed DC motor drives
- General purpose motion control applications
Procurement Notes
Verify the specific suffix against the manufacturer datasheet to ensure correct packaging and pinout compatibility. Confirm that the 28-PowerTSSOP package dimensions align with your PCB footprint requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the operating voltage and current ratings match your motor specifications before integration.
Selection Notes
Select this component when a dual-bridge solution is required for stepper or DC motor applications. The 1.6A output current rating suits moderate load requirements. The wide supply voltage range allows flexibility in power system design. Consider the parallel interface complexity compared to serial alternatives if pin count is constrained.
Part Context
This part belongs to the DRV8812 family of dual-bridge motor controllers from Texas Instruments. It is distinct from the DRV8811, which offers lower current capabilities, and the DRV8813, which may feature different control interfaces. The PWPR suffix indicates the tape-and-reel packaging variant of the PWP core device.
Replacement Considerations
The DRV8812PWPR is a direct packaging alternative offering identical electrical characteristics. The DRV8812RHDR provides the same functionality in a VQFN-28 package, requiring layout adjustments. Verify pin-to-pin compatibility and thermal performance when substituting.
