DRV8873QPWPRQ1 - 40V 10A H-Bridge Motor Driver | TI
MPN： DRV8873QPWPRQ1 ✓ 啟用中DRV8873QPWPRQ1 概覽
A brushed DC motor driver is a power management IC that controls direction and speed of motors by switching four N-channel MOSFETs in an H-bridge configuration. It belongs to the motor driver family within broader power management ICs, enabling bidirectional control in body electronics. Integrated low-resistance MOSFETs deliver high efficiency and minimal heat.
Key features include integrated current sensing with a proportional IPROPI output, supporting stall detection and torque regulation without external shunts. The device supports both PH/EN and PWM control interfaces for flexible speed and direction management. Protection features include overcurrent, overtemperature, and undervoltage lockout, ensuring robust operation. Low quiescent current and sleep mode reduce battery drain in parked vehicles.
The architecture integrates the H-bridge and current feedback, offloading the MCU from external amplifiers and sense resistors. The PowerPAD package provides low thermal resistance, enabling sustained multi-ampere loads on multilayer PCBs with adequate copper area. This simplifies system design and reduces BOM cost.
Typical applications include power window lifters, sunroof actuators, seat adjusters, and other body control motor loads in vehicles. The wide input range also supports 12V and 24V automotive systems.
Design tip: at high currents, provide generous copper under the PowerPAD and place decoupling capacitors close to the VM pin to manage di/dt transients. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.

典型應用
DRV8873QPWPRQ1 適用於 6 應用s: Power Window Lifter, Sunroof Actuator, Seat Adjuster, Body Control Module (BCM), Automotive HVAC Blower, Robotics and Automation.
Power Window Lifter
The DRV8873QPWPRQ1 is ideal for power window lifters in automotive body electronics. Its 10A peak current capacity handles the stall current of window motors, while the integrated IPROPI current sense enables stall detection to prevent glass damage. The 4.5V-38V supply voltage covers 12V and 24V systems, and the PWM interface allows precise speed control for anti-pinch functionality. With AEC-Q100 qualification, it ensures reliable operation over the vehicle's lifetime. The small 24-pin HTSSOP package fits in the door module space. When used with a 10µF ceramic capacitor at VM, the driver maintains smooth operation under load. The power dissipation for a typical 5A stall condition is about 12W, requiring a thermal pad connection to the PCB copper area.

Sunroof Actuator
Sunroof actuators require bidirectional motor control with precise speed and stall detection. The DRV8873QPWPRQ1 provides all that with its H-bridge topology and IPROPI output. The device handles peak currents up to 10A, accommodating the high torque needed to move the sunroof panel. Its PH/EN interface simplifies control from the body control module, reducing software overhead. The overtemperature protection ensures the driver shuts down safely during prolonged stalls. At 12V supply and 5A load, the device dissipates approximately 10W, which is manageable with a 2 oz copper pour under the PowerPAD. The 38V maximum input also allows load dump transients without damage. This driver is a robust choice for sunroof systems.

Seat Adjuster
The DRV8873QPWPRQ1 drives seat adjuster motors with smooth bidirectional motion and stall detection. Its 10A peak current supports high-torque motors for seat recline and slide functions. The integrated current sensing via IPROPI allows the system to detect obstructions, a safety requirement in modern vehicles. The 4.5V-38V supply range accommodates both 12V and 24V seat systems, and the PWM interface enables soft-start to reduce mechanical stress. AEC-Q100 qualification ensures reliability in the harsh automotive environment. With proper PCB thermal design, the device can handle the sustained currents typical of seat adjustment. The 24-pin HTSSOP package with PowerPAD permits compact placement under the seat. The device also includes undervoltage lockout to protect against low battery voltage.

Body Control Module (BCM)
The DRV8873QPWPRQ1 serves as a central motor driver in the body control module, controlling multiple DC loads such as wipers, fuel pumps, and door locks. Its 10A peak current and wide 4.5V-38V input range make it versatile across different load types. The device's PH/EN interface integrates easily with microcontroller GPIOs, and the integrated current sense provides feedback for diagnostics. The overtemperature protection and undervoltage lockout contribute to system robustness. With sleep mode, the driver draws minimal current when the vehicle is parked, preserving battery life. The PowerPAD package aids thermal dissipation for continuous operation. The AEC-Q100 qualification ensures it meets automotive quality standards. This driver reduces BOM count by replacing discrete MOSFET bridges and sense circuits.

Automotive HVAC Blower
Blower motors in HVAC systems require variable speed control with high reliability. The DRV8873QPWPRQ1 provides PWM control for smooth speed adjustment, with a 10A peak current that handles blower startup surges. Its wide supply range covers the voltage fluctuations common in automotive environments. The integrated current sensing allows monitoring of blower load for diagnostics. The device's low quiescent current in sleep mode helps maintain battery charge when the ignition is off. With overtemperature protection, it prevents damage from stalled blower conditions. The 24-pin HTSSOP package enables compact integration in the HVAC controller. The AEC-Q100 qualification ensures it withstands the temperature extremes of the engine compartment. Proper decoupling at VM is critical to handle the PWM switching transients.

Robotics and Automation
Beyond automotive, the DRV8873QPWPRQ1 is also used in robotics and industrial automation for driving brushed DC motors in actuators. Its 10A peak current and wide supply voltage make it suitable for 12V and 24V robot joints and grippers. The integrated current sensing enables force control and stall detection in robotic applications. The PWM interface allows precise velocity control. Though not AEC-Q100 qualified for non-automotive use, the device provides robust protection with overcurrent and overtemperature. For high-current robotics, the PowerPAD package requires a well-designed heat spreader. The device can be controlled from an MCU with minimal external components, simplifying the electronics in compact robots. The 38V maximum input handles voltage spikes from inductive loads. This driver offers a compact solution for motion control in industrial robots.

設計說明
Estimated: at 12V supply, 5A load, power dissipation = (12V - 0.5V) * 5A ≈ 57.5W? Actually, for motor driver, power is I²R. With RDS(on) of about 0.5Ω per MOSFET pair, power ≈ I² * 2 * RDS(on) = 25 * 1 = 25W. This requires a copper pour of at least 2 sq. in. under the PowerPAD and airflow. For 10A peak, dissipation rises to 100W, so thermal management is critical. Use the PowerPAD to solder to a thermal vias array.
Place 10µF and 0.1µF ceramic capacitors as close as possible to the VM pin to absorb high di/dt switching transients. The VM trace should be wide and short to minimize inductance. Route the IPROPI output away from high-current traces to avoid noise coupling. Connect the PowerPAD to a large copper area on the top and bottom layers with thermal vias.
Do not exceed the absolute maximum voltage of 38V. Ensure the PWM frequency does not cause excessive switching losses. For PWM control, the dead time must be adequate to prevent shoot-through. The IPROPI capacitor (typically 1nF to 10nF) is required for stable current sensing. Missing this capacitor can cause erroneous stall detection.
