DRV8833PWP

Overview

The DRV8833PWP is a dual H-bridge motor driver manufactured by Texas Instruments, designed for low-voltage applications. It operates within a supply voltage range of 2.7 V to 10.8 V and supports peak output currents up to 2 A per bridge. The device integrates current regulation and features a PWM control interface. It is housed in a 16-pin HTSSOP package with an exposed PowerPad for thermal management. The component functions effectively as a driver for one or two DC motors or a single bipolar stepper motor.

Feature Summary

• Integrates dual H-bridge architecture for independent control of two DC motors or one bipolar stepper motor
• Includes built-in current regulation to manage load conditions and protect the circuit
• Supports simple pulse-width modulation (PWM) interface for straightforward digital control
• Features low-current sleep mode to minimize power consumption during idle periods

Applications

• Battery-powered smart locks and electronic access systems
• Vending machines requiring precise motor actuation
• Automotive window and seat adjustment mechanisms
• Small appliance fan and pump control circuits

Procurement Notes

Verify the specific suffix against the manufacturer's latest datasheet to confirm pinout compatibility and electrical ratings. Ensure the ordering part number matches the required package variant and temperature grade. Cross-reference the component marking with official silkscreen documentation to prevent counterfeit substitution. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when designing systems requiring dual independent motor channels within a compact footprint. It is suitable for applications powered by single-cell lithium-ion batteries or multiple AA/AAA cells. Consider the thermal performance of the HTSSOP package relative to the expected continuous current load. Evaluate the need for integrated current limiting versus external protection schemes based on system safety requirements.

Part Context

This device belongs to the DRV8833 family of low-voltage motor drivers from Texas Instruments. The family includes variants with different current capabilities and packaging options, such as the DRV8833C for lower current applications. The PWP suffix specifically denotes the HTSSOP-16 package configuration. This series is engineered for cost-sensitive consumer electronics and industrial automation tasks.

Replacement Considerations

Direct substitutes include other DRV8833 variants like DRV8833PWPR or DRV8833CPWPR, provided the current rating meets the application needs. Verify that alternative packages maintain compatible pin assignments and thermal dissipation characteristics. Check for any differences in operating temperature ranges or control logic levels before implementation.
