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 | OUT2P | output | Upper-side driver output for the second coil leg, intended to drive the P-channel top-side switch of the H-bridge. |+| 2 | OUT2N | output | Lower-side driver output for the second coil leg, intended to drive the N-channel bottom-side switch of the H-bridge. |+| 3 | VCC | power_in | Supply input for the device; a 0.1 µF to 1 µF capacitor (CM) is connected between VCC and GND close to the pin, and a zener diode should be used if kickback causes excessive supply rise, with recommended supply of 6 V to 16 V and an 18 V absolute maximum. |+| 4 | VLIM | input | Current-limit threshold input that activates the current limiter when the SENSE voltage exceeds the VLIM voltage, and must be connected to 6VREG when not used. |+| 5 | SENSE | input | Current sense input for the current limiter in the H-bridge return path, and must be connected to GND when not used. |+| 6 | RMI | input | Minimum speed setting input set by an external resistor; connect to 6VREG when not used, and insert a current-limiting resistor if device power may be removed before power is removed from RMI to prevent large inflow current. |+| 7 | VTH | input | Speed control input that accepts a DC voltage (0 V to 7 V in full-speed mode) or a pulsed PWM signal, and must be connected to GND for full speed when speed control is not used. |+| 8 | CPWM | output | PWM oscillator timing pin where a capacitor sets the PWM oscillation frequency (CP = 100 pF gives 25 kHz), and the capacitor must be fitted even when speed control is not used. |+| 9 | FG | output | Open-collector rotation speed output derived from the phase shift of the drive, which requires an external pull-up and should be left open when not used. |+| 10 | RD | output | Open-collector lock detection output that is low during rotation and high at stop, and should be left open when not used. |+| 11 | IN- | input | Negative Hall sensor input to the internal comparator, with traces kept short and an optional capacitor between IN+ and IN- to limit noise. |+| 12 | HB | output | Hall element bias output providing a 1.5 V constant-voltage output for the Hall sensor. |+| 13 | IN+ | input | Positive Hall sensor input to a comparator with 20 mV hysteresis, where the Hall input level should be at least three times the hysteresis (60 mVp-p). |+| 14 | CT | output | Lock detection timing pin to which the lock detection capacitor is connected; the lock detection feature is disabled if this pin is tied to ground. |+| 15 | ROFF | input | Soft-switching time setting input that sets the soft switching time to cut reactive current before phase change, and must be connected to 6VREG when not used. |+| 16 | 6VREG | output | 6 V regulator output that supplies Hall bias, pull-ups and the pin-setting connections, specified at 5.8 V to 6.15 V at 5 mA load. |+| 17 | SGND | power_in | Signal ground connected to the control circuit power supply system. |+| 18 | VOVER | output | Constant-voltage bias output used for 24 V and 48 V operation to limit VCC to permissible values, which requires a current-limiting resistor and should be left open when not used. |+| 19 | OUT1N | output | Lower-side driver output for the first coil leg, intended to drive the N-channel bottom-side switch of the H-bridge. |+| 20 | OUT1P | output | Upper-side driver output for the first coil leg, intended to drive the P-channel top-side switch of the H-bridge. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-20 |+| Category | Motor Driver ICs |+| Pins | 20 |++## CAD (KiCad official)++- Symbol: `TMP814PWR`+- Footprint: `Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm`+- 3D model: TSSOP-20 (KiCad packages3D, STEP)+- 3D model files: `tmp814pwr-etched.step` / `tmp814pwr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tmp814pwr.step` / `tmp814pwr.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tmp814.pdf) (23 pp, sha256 `6730941610780244`, retrieved 2026-10-08, tier: manufacturer)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
