DRV11873PWPR from Texas Instruments, in a HTSSOP-16-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | FS | input | Motor parameter adjustment pin; pull low for a lower-speed motor and pull high for a high-speed motor (state latched only at power-up). |
| 2 | FG | output | Open-drain frequency generator output whose period equals 6 electrical states, used to indicate motor speed/phase; requires external pull-up resistor (100 kΩ or higher) to V5 or VCC. |
| 3 | RD | output | Open-drain lock-detect output that is pulled high through an external pull-up resistor to VCC or 5 V when the motor lock condition is detected. |
| 4 | VCP | power_out | Charge pump output that supplies the boosted gate-drive voltage for the internal high-side MOSFETs. |
| 5 | CPP | passive | Charge pump conversion terminal; connects to an external flying capacitor together with CPN for the internal charge pump. |
| 6 | CPN | passive | Charge pump conversion terminal; connects to an external flying capacitor together with CPP for the internal charge pump. |
| 7 | W | output | Phase W motor drive output from the integrated power MOSFET half-bridge, rated for up to 1.5 A continuous / 2 A peak drive current. |
| 8 | GND | power_in | Ground pin; must be connected to system ground and to the thermal pad for proper operation and heat dissipation. |
| 9 | V | power_in | Phase V motor drive output from the integrated power MOSFET half-bridge, rated for up to 1.5 A continuous / 2 A peak drive current. |
| 10 | U | output | Phase U motor drive output from the integrated power MOSFET half-bridge, rated for up to 1.5 A continuous / 2 A peak drive current. |
| 11 | VCC | power_in | Input supply voltage for the motor and chip, recommended operating range 5 V to 16 V. |
| 12 | V5 | power_out | 5-V LDO regulator output capable of sourcing up to 20 mA for external use; requires a 2.2-µF ceramic decoupling capacitor to ground. |
| 13 | COM | input | Motor common terminal input used as the BEMF reference; if the motor has no common wire, a simulated COM node must be created with three resistors in a wye configuration. |
| 14 | CS | input | Overcurrent threshold set-up pin; an external resistor to ground sets the current limit per Ilimit(A)=6600/RCS(Ω), valid for 500 mA < Ilimit < 2000 mA; shorting to ground disables overcurrent protection. |
| 15 | FR | input | Forward/reverse rotation control pin; set high for reverse rotation, set low or floating for forward rotation (latched at power-up, resettable via a PWMIN low pulse of defined duration). |
| 16 | PWMIN | input | PWM input pin (7 kHz to 100 kHz) used to set motor speed; internally pulled up to V5 and converted to a fixed switching frequency (125 kHz with FS high, 62.5 kHz with FS low) on the MOSFET driver. |
| 17 | PowerPAD | power_in | Exposed thermal pad (PowerPAD) on the package underside; must be connected to GND copper with vias for heat dissipation per the layout guidelines. |
