Texas Instruments DRV8962DDWR

Overview

DRV8962DDWR from Texas Instruments is a four-channel half-bridge motor driver IC with integrated high-side current sensing, 4.5–65 V operating range, 50 mΩ R_DS(ON) at 24 V/25 °C, 5-A per output (DDW package), and ±3.5% current sense accuracy across 40–100% rated load. It drives solenoids, stepper motors, brushed-DC motors, TECs, or BLDC/PMSM motors in industrial motion control systems.

For engineers reviewing the DRV8962DDWR datasheet, DRV8962DDWR pinout, DRV8962DDWR application, or DRV8962DDWR equivalent, key selection criteria include its HTSSOP-44 thermal pad package, independent half-bridge enable/PWM control, programmable rise/fall time via MODE pin, integrated OCP/UVLO/OTSD protection, and IPROPI-based closed-loop current feedback without external shunts.

Technical Context

The DRV8962DDWR implements four independent N-channel half-bridges with charge-pump-driven high-side gates enabling 100% duty-cycle operation. Its current regulation uses high-side MOSFET sensing with adjustable VREF threshold and deglitch/blanking timing (t_DEG = 0.5 µs, t_BLK = 1.5 µs) to suppress false OCP triggers during PWM transitions.

Protection logic includes VM UVLO (4.2–4.35 V trip), charge pump undervoltage detection, cycle-by-cycle overcurrent monitoring (8-A trip for DDW), and thermal shutdown at 150–180 °C with 20 °C hysteresis. Fault status is reported via open-drain nFAULT with auto-retry or latch-off recovery selectable by OCPM pin voltage.

FAQ

What is the maximum continuous output current per channel for DRV8962DDWR?

The DRV8962DDWR supports up to 5 A continuous current per output channel when mounted on a PCB with adequate copper pour and thermal vias under its bottom-exposed PowerPAD™. This rating assumes ambient temperature ≤125 °C, VM = 24 V, and proper decoupling per TI's layout guidelines. Derating applies above 100 °C junction temperature.

Does DRV8962DDWR require an external shunt resistor for current sensing?

No, the DRV8962DDWR does not require an external shunt resistor for basic current sensing. It provides four IPROPI pins that source 212 µA per ampere of high-side current with ±3.5% accuracy (40–100% rated load). An external RIPROPI resistor converts this to a measurable voltage. External shunts are optional for higher accuracy.

How is fault recovery configured on DRV8962DDWR?

Fault recovery on the DRV8962DDWR is selected via the OCPM pin voltage: <0.8 V configures auto-retry mode (4.1 ms interval), while >2.0 V enables latch-off mode requiring an nSLEEP reset pulse. Both methods report faults on the open-drain nFAULT pin, which must be pulled up externally to DVDD or VCC.

Can DRV8962DDWR drive a stepper motor in microstepping mode?

The DRV8962DDWR supports full- and half-step operation of bipolar stepper motors using two half-bridges per phase. While it lacks native microstepping waveform generation, microstepping can be implemented externally via PWM modulation of INx/ENx signals and VREF-adjusted current regulation-enabling smooth motion control with torque consistency.

What thermal design considerations apply to DRV8962DDWR in HTSSOP-44 (DDW) package?

For the DRV8962DDWR in DDW package, thermal design must prioritize bottom-side heat transfer: use ≥4 thermal vias (0.3 mm diameter) under the PowerPAD™ connected to a solid inner-layer copper pour, minimize trace length to VM/PGND planes, and maintain ≥20 mm² of 2-oz copper per watt. R_θJA drops from 22.2 to <10 °C/W with optimal layout.
