A PHASE pin sets direction and ENABLE drives PWM, while a SENSE pin plus VPROPI give a proportional current-sense output for torque control, and an nFAULT flag reports overcurrent, overtemperature, and undervoltage. An internal charge pump (CP1/CP2/VCP) drives the high-side gates, and nSLEEP powers it down. The PowerPAD carries heat into the board. A full-featured single-motor driver.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | nFAULT | output | Fault indication. Pulled logic low with fault condition. Open-drain output requires an external pullup resistor. VOL = 0.4 V max at Isink = 1 mA. |+| 2 | MODE1 | input | Mode 1 logic input. Combined with MODE2 selects the decay/mode behavior of the H-bridge. |+| 3 | PHASE | input | Phase logic input. Controls the direction of the H-bridge output. Logic-level input referenced to VDD (0-5.5 V). |+| 4 | GND | power_in | Device ground. |+| 5 | nSLEEP | input | Sleep-mode input. Logic high enables the device; logic low enters low-power sleep mode. Internal pulldown resistor. VIH = 2.7 V, VIL = 0.8 V. |+| 6 | ENABLE | input | Enable logic input. Set high to enable the H-bridge; can also be pulsed for PWM current control (0-100 kHz). |+| 7 | OUT+ | output | DMOS H-bridge output. Connect to one motor terminal. Rated ±2.8 A peak, RDS(on) ~0.4 Ω typical. |+| 8 | SENSE | bidirectional | Sense power return. Connect low-side H-bridge return through a sense resistor (e.g. 0.2 Ω) to ground; internally sensed to drive VPROPI current-monitor output. VSense range -500 to +500 mV; VTRP = 500 mV. |+| 9 | VBB | power_in | Driver supply voltage, 8-36 V (abs-max 40 V). Bypass to GND with 0.1-µF ceramic capacitors plus a bulk capacitor rated for VBB. |+| 10 | OUT- | output | DMOS H-bridge output. Connect to the other motor terminal. Rated ±2.8 A peak, RDS(on) ~0.4 Ω typical. |+| 11 | CP1 | passive | Charge pump switching node. Connect a 0.1-µF X7R ceramic capacitor rated for VBB between CP1 and CP2. |+| 12 | CP2 | passive | Charge pump switching node. Connect a 0.1-µF X7R ceramic capacitor rated for VBB between CP1 and CP2. |+| 13 | GND | power_in | Device ground. |+| 14 | VCP | passive | Charge pump reservoir capacitor pin. Connect an X7R, 0.1-µF, 16-V ceramic capacitor to VBB. Charge pump voltage abs-max VBB+17 V. |+| 15 | VPROPI | output | Voltage output proportional to winding (motor) current, driven by an internal differential amplifier with gain DAGain = 5 V/V (over Sense = 0.1-0.4 V). Suitable for feeding an external ADC for current monitoring. |+| 16 | MODE2 | input | Mode 2 logic input. Combined with MODE1 selects the decay/mode behavior of the H-bridge. |+| 17 | PowerPAD | power_in | Exposed pad for thermal dissipation. Connect to ground. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Brushed DC motor driver (single H-bridge) |+| Supply (VBB) | 8-36 V |+| Output current | 2.8 A |+| Control | PHASE (direction) + ENABLE (PWM) |+| Current sense | Proportional output (VPROPI) |+| Diagnostics | nFAULT (OCP, OTP, UVLO) |+| Package | HTSSOP-16 (PowerPAD) |++## Ordering variants++- `DRV8801PWP (HTSSOP-16)`+- `DRV8801PWPR (HTSSOP-16, tape & reel)`++## CAD (KiCad official)++- Symbol: `Driver_Motor:DRV8801PWP (KiCad official)`+- Footprint: `Package_SO:HTSSOP-16-1EP_4.4x5mm_P0.65mm_EP3.4x5mm_Mask3x3mm_ThermalVias`+- 3D model: HTSSOP-16 PowerPAD (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/drv8801.pdf) (39 pp, sha256 `2a6e17a5def32c61`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
