Texas Instruments DRV8876QPWPRQ1

Overview

DRV8876QPWPRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive H-bridge motor driver with integrated N-channel power stage, current sensing (IPROPI), and programmable current regulation. It operates from 4.5 V to 37 V, delivers up to 3.5-A peak output current, and supports PH/EN, PWM, and independent half-bridge control modes for brushed DC motors in safety-critical systems.

For engineers reviewing the DRV8876QPWPRQ1 datasheet, DRV8876QPWPRQ1 pinout, DRV8876QPWPRQ1 application, or DRV8876QPWPRQ1 equivalent, this page provides verified functional safety–capable motor driver specifications, HTSSOP-16 package layout, real-world current regulation behavior, and validated automotive-grade alternatives for HVAC damper, side mirror, and e-shifter designs.

Technical Context

The DRV8876QPWPRQ1 implements a charge-pump–driven N-channel H-bridge enabling 100% duty-cycle operation and high efficiency across its 4.5–37-V supply range. Its internal current mirror architecture on IPROPI delivers proportional analog current (1000 µA/A scaling) without external shunt resistors, supporting continuous current monitoring during both drive and slow-decay brake phases.

Control flexibility is achieved via tri-level PMODE (PH/EN, PWM, independent half-bridge) and quad-level IMODE (cycle-by-cycle or fixed off-time current regulation). Protection includes UVLO (4.45 V rising), OCP (3.5-A trip), thermal shutdown (175°C), and fault reporting via open-drain nFAULT - all qualified per AEC-Q100 Grade 1 (–40°C to +125°C TA).

FAQ

What is the maximum continuous output current rating for DRV8876QPWPRQ1?

The DRV8876QPWPRQ1 is rated for 3.5-A peak output current, but continuous current depends on PCB thermal design. With proper copper area on the thermal pad and PGND planes, typical continuous current is ~2.2 A at +85°C ambient. Derating is required above 85°C ambient or with limited airflow; refer to R_θJB = 20.5°C/W and thermal characteristics in Section 6.4 of the DRV8876QPWPRQ1 datasheet for layout-specific calculations.

How does the IPROPI pin function in DRV8876QPWPRQ1, and what external components are needed?

The IPROPI pin on DRV8876QPWPRQ1 outputs a current proportional to motor load current (1000 µA/A scaling). To convert this to a measurable voltage, connect an external resistor (RIPROPI) between IPROPI and GND. Typical values range from 1 kΩ to 10 kΩ depending on expected current and MCU ADC range. The DRV8876QPWPRQ1 also includes an internal voltage clamp referenced to VREF to protect the ADC input during overcurrent events.

Can DRV8876QPWPRQ1 operate with 3.3-V logic inputs, and what are the voltage thresholds?

Yes, DRV8876QPWPRQ1 supports 1.8-V, 3.3-V, and 5-V logic inputs. For 3.3-V systems, the input logic high threshold (VIH) is 1.5 V minimum, and logic low (VIL) is 0.8 V maximum when VVM ≥ 5 V - ensuring robust compatibility with standard 3.3-V microcontrollers. All control pins (EN/IN1, PH/IN2, nSLEEP, PMODE, IMODE) include internal pulldown or pullup resistors for defined default states.

What protection features are integrated into DRV8876QPWPRQ1, and how are faults reported?

DRV8876QPWPRQ1 integrates undervoltage lockout (UVLO), charge pump undervoltage (CPUV), overcurrent protection (OCP), and thermal shutdown (TSD). Fault conditions are reported collectively on the open-drain nFAULT pin, which pulls low during any active fault. The IMODE pin selects whether OCP triggers automatic retry (default) or latches outputs off - configurable per application safety requirements.

Is DRV8876QPWPRQ1 pin-compatible with other devices in the DRV887x-Q1 family?

Yes, DRV8876QPWPRQ1 is pin-compatible with DRV8874QPWPRQ1 and DRV8876NQPWPRQ1 in the same HTSSOP-16 (PWP) package. They share identical pinout, control interface, and peripheral connections (VCP, CPH, CPL, VREF, IPROPI, nFAULT, etc.), differing only in R_DS(on), peak current rating, and current sense accuracy - enabling drop-in substitution for performance tuning without PCB redesign.
