DRV8876PWPT 概要
An H-bridge motor driver is a power management IC that controls the direction and speed of a brushed DC motor by selectively turning on four transistors in an H configuration. The DRV8876 integrates the H-bridge, gate drivers, and protection circuitry into a single package, simplifying PCB design and reducing component count. It is part of the DRV887x family of brushed DC motor drivers, which are known for their flexibility and robustness.
Key features include a 4.5-V to 37-V operating supply voltage, 3.5-A peak drive current, integrated current sensing with adjustable current regulation, and a low-power sleep mode. The device also provides overcurrent, overtemperature, and undervoltage lockout protection. The integrated current sense amplifier outputs a voltage proportional to the motor current, enabling precise torque control without external sense resistors.
The DRV8876 uses an N-channel H-bridge architecture with a charge pump to drive the high-side FETs, achieving low RDS(on) and high efficiency. The current regulation feature allows the motor current to be limited to a programmable level, protecting the motor and power supply. The device is designed for industrial and consumer applications, including printers, robotics, and home appliances.
Typical applications include brushed DC motor control in printers, robotics, and industrial automation. The wide supply voltage range and integrated protection make it suitable for battery-powered and industrial systems. The HTSSOP package with exposed thermal pad aids in heat dissipation, enabling reliable operation at high currents.
When designing with the DRV8876, ensure adequate PCB copper area for thermal management, and place the charge pump capacitor close to the CP1 and CP2 pins. The current sense resistor should be placed near the ISEN pin to minimize noise. Proper decoupling on the VM pin is essential for stable operation.

設計ノート
The DRV8876PWPT in HTSSOP-16 package has an exposed thermal pad that must be soldered to a PCB copper area for effective heat dissipation. For continuous operation at high currents, ensure the PCB has adequate copper area (at least 1 square inch) and thermal vias to the ground plane. The thermal resistance (theta_JA) is typically around 40°C/W, so at 3.5A and 12V supply with 6V motor voltage, power dissipation is approximately 21W, which would require aggressive cooling. In practice, limit continuous current to lower levels or use PWM to reduce average power.
Place the charge pump capacitor (typically 0.1uF) as close as possible to the CP1 and CP2 pins. The VM pin should be decoupled with a 10uF ceramic capacitor placed near the pin, and a 0.1uF capacitor in parallel for high-frequency noise. The current sense resistor (if used) should be placed close to the ISEN pin to minimize parasitic inductance. The exposed thermal pad should be connected to the ground plane with multiple vias for optimal thermal performance.
Do not exceed the absolute maximum supply voltage of 40V. Ensure the logic supply (VDD) is within the specified range (typically 3.3V or 5V). The SLEEP pin should be pulled high for normal operation and low for sleep mode; do not leave it floating. The nFAULT pin is open-drain and requires a pull-up resistor. When using current regulation, set the VREF voltage correctly to achieve the desired current limit. Also, ensure the motor's back-EMF does not exceed the supply voltage, which could cause issues.
