The DRV8801 is a full H-bridge motor driver for one brushed DC motor, running from 8 V to 36 V with peak output currents up to ±2.8 A and a simple PHASE and ENABLE interface. It suits larger robots than the small low-voltage drivers. The DRV8800 is the sibling in the same datasheet. Figures are from the Texas Instruments DRV880x datasheet SLVS855K.
Key specifications
| Supply | 8–36 V |
|---|---|

| RDS(on) | 0.4 Ω typical |
| Interface | PHASE/ENABLE |
| Sleep | nSLEEP pin |
| Packages | HTSSOP-16, WQFN-16 |
What the datasheet promises
| Item | Datasheet value |
|---|---|
| Function | Full H-bridge for a brushed DC motor, one winding of a stepper, or a solenoid |
| Supply voltage | 8 V to 36 V |
| Peak output current | Up to ±2.8 A |
| On-resistance | 0.4 Ω typical |
| Control | PHASE sets direction, ENABLE turns the bridge on; 100 percent PWM duty cycle is supported |
| Decay modes | MODE1 chooses fast or slow decay; MODE2 chooses high-side or low-side slow decay |
| Current sensing | SENSE pin with an external resistor; the pin table also lists a VPROPI analog current output |
| Sleep | Low-power sleep mode through nSLEEP |
| Protection | Undervoltage lockout, charge pump undervoltage, overcurrent, short-to-supply, short-to-ground, overtemperature warning and shutdown, with an nFAULT output |
| Packages | HTSSOP-16 (5 × 4.4 mm) and WQFN-16 (4 × 4 mm) |
The nFAULT output is open-drain, so it needs a pull-up resistor. Peak current is not continuous current: how much the chip can carry for long depends on the board layout and copper, as the datasheet application section describes.
Using it on a robot
- Drive a 12 V or 24 V brushed gearmotor in a larger robot, within the current limits in the datasheet.
- Use the nFAULT line to stop the robot if the driver detects a short or overheating.
- Use the braking function the datasheet describes to stop the motor, instead of just removing ENABLE.
- For a smaller, lower-voltage driver see the DRV8837.
