DRV8835DSSR

Overview

The DRV8835DSSR is a dual low-voltage H-bridge motor driver manufactured by Texas Instruments, designed for battery-powered motion control applications. It features two integrated H-bridge drivers capable of delivering up to 1.5A continuous output current per bridge. The device operates with an output supply voltage range of 2V to 11V and a logic supply voltage range of 2V to 7V. Packaged in a compact 12-pin WSON (WSON-12) surface-mount format, it supports driving one stepper motor or two DC motors. Key electrical parameters include a maximum operating temperature of +85°C and a minimum of -40°C.

Feature Summary

• Integrates two H-bridge drivers with N-channel power MOSFETs for efficient motor winding drive.
• Includes internal circuitry to regulate and limit winding current for enhanced protection.
• Supports selectable phase/enable and IN/IN interfaces compatible with industrial standards.
• Features built-in shutdown functions including overcurrent, short-circuit, undervoltage lockout, and overtemperature protection.

Applications

• Camera and camcorder equipment such as lens focus and zoom motor control
• Consumer toys including smart cars and robotic arms
• Battery-powered portable devices requiring low-voltage motion control

Procurement Notes

Verify the specific suffix 'DSSR' against the official Texas Instruments datasheet to confirm the reel packaging configuration and tape width specifications. Ensure that the ordering documentation matches the required WSON-12 package dimensions and PowerPAD thermal pad requirements for proper PCB layout integration.

Selection Notes

Select this component when a dual H-bridge solution is required for driving either a single bipolar stepper motor or two separate brushed DC motors within a low-voltage system. It is suitable for designs prioritizing space efficiency due to its small WSON footprint while maintaining robust current handling capabilities for typical consumer electronics loads.

Part Context

This part belongs to the DRV8834/35/36 family of dual low-voltage H-bridge ICs from Texas Instruments. These devices are engineered specifically for low-voltage or battery-powered motion control applications, offering an integrated solution that simplifies design complexity compared to discrete MOSFET implementations.

Replacement Considerations

Compatible substitutes within the same family include the DRV8834 and DRV8836, which share similar dual H-bridge architectures but may differ in pinout configurations or specific current ratings. Verify functional equivalence and mechanical compatibility before substitution.
