- Automotive AEC-Q100 qualification (vs DRV8376HNLGR)
- Higher voltage and current capability (vs DRV8313PWPR)
Design Notes
The DRV8376HQNLGRQ1 can dissipate significant power at high currents. With RDS(on) of 400mΩ and 4A peak current, power dissipation can reach 6.4W per bridge. Ensure adequate PCB copper area and thermal vias to keep junction temperature below 125°C. The exposed pad must be soldered to a large ground plane for effective heat sinking.
Place 100nF ceramic capacitors close to each power pin (VM, VCP, VREG) and a bulk capacitor (≥10µF) on VM. The current sense output (ISEN) should be routed with Kelvin connections to avoid noise. Keep PWM traces short and away from high-current paths to minimize EMI.
Do not exceed the absolute maximum voltage of 70V on VM. Ensure proper sequencing of VDD and VM to avoid latch-up. The integrated current sensing requires calibration; use the datasheet's recommended gain settings. Also, verify the sleep mode entry/exit timing to prevent unintended motor activation.
