Texas Instruments DRV8410PWPR

Overview

DRV8410PWPR from Texas Instruments is a dual H-bridge motor driver IC designed for precise current-regulated control of brushed DC or bipolar stepper motors in space-constrained, battery-powered systems. It delivers 2.5A peak output current per bridge, operates from 1.65V to 11V, features 800mΩ typical total R_DS(on) (HS + LS), and integrates external-shunt-based current regulation with 200mV trip threshold. It is used in POS printers and video security cameras for reliable bidirectional motor actuation under low-voltage brownout conditions.

For engineers reviewing the DRV8410PWPR datasheet, DRV8410PWPR pinout, DRV8410PWPR application, or DRV8410PWPR equivalent, key selection criteria include its dual-bridge architecture with independent AISEN/BISEN current sensing, ultra-low 30nA sleep current at 5V, 16-pin HTSSOP package with PowerPAD™, and compatibility with 1.8V/3.3V/5V logic interfaces - all critical for portable and thermally constrained motor control designs.

Technical Context

The DRV8410PWPR implements two independent N-channel H-bridges with integrated charge pump enabling full enhancement of high-side FETs down to 1.65V supply. Each bridge uses PWM-controlled input logic (AIN1/AIN2, BIN1/BIN2) to execute forward, reverse, brake, or coast states, with automatic 400ns dead-time insertion to prevent shoot-through.

Current regulation operates via external sense resistors on AISEN and BISEN pins, comparing sensed voltage against a 200mV internal reference to trigger 20µs off-time chopping. Protection includes auto-retry overcurrent detection (2.5A trip), thermal shutdown (153°C activation), and VM undervoltage lockout (1.6V rising threshold), all signaled via open-drain nFAULT.

FAQ

What is the maximum continuous current DRV8410PWPR can deliver per H-bridge?

DRV8410PWPR is rated for 2.5A peak output current per bridge, but continuous current depends on PCB thermal design. With proper copper pour and thermal pad soldering, it sustains ~1.5A continuous per bridge at 25°C ambient. Derating is required above 85°C junction temperature; refer to R_θJA = 48.3°C/W and thermal shutdown at 153°C to ensure safe operation in your layout.

Does DRV8410PWPR support microstepping for stepper motors?

DRV8410PWPR does not implement microstepping internally - it is a dual H-bridge driver that provides full-step and half-step control via external logic. Microstepping requires an external indexer or MCU generating phased PWM signals to AIN1/AIN2 and BIN1/BIN2. The device's current regulation (via AISEN/BISEN) stabilizes winding current during microstep transitions, improving torque consistency.

Can DRV8410PWPR operate from a single 1.8V supply?

Yes, DRV8410PWPR supports VM down to 1.65V, making it compatible with 1.8V systems. Its integrated charge pump ensures full gate drive for high-side N-FETs even at this rail. Logic inputs accept 1.8V-compatible levels (VIH ≥ 1.45V), and sleep current remains ≤30nA - ideal for ultra-low-power 1.8V microcontroller interfaces.

How do I configure DRV8410PWPR for parallel bridge operation?

To configure DRV8410PWPR for parallel bridge mode, connect AIN1 and BIN1 to the same IN1 signal, AIN2 and BIN2 to the same IN2 signal, AOUT1 and BOUT1 to OUT1, AOUT2 and BOUT2 to OUT2, and tie AISEN and BISEN directly to GND (disabling current regulation). This halves effective R_DS(on) to ~400mΩ and doubles peak current capability to 5A shared across both bridges.

What protection features are integrated into DRV8410PWPR?

DRV8410PWPR integrates three core protections: VM undervoltage lockout (UVLO) with 1.6V rising threshold, auto-retry overcurrent protection (OCP) triggered at 2.5A with 1.6ms retry interval, and thermal shutdown (TSD) activating at 153°C. All faults assert the open-drain nFAULT pin low, enabling simple MCU monitoring without additional sensing circuitry.
