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 (P-channel) driver output with an absolute maximum output voltage of 18 V and a continuous output current limit of 20 mA. |+| 2 | OUT2N | output | Lower-side (N-channel) driver output with an absolute maximum output voltage of 18 V and a continuous output current limit of -20 mA. |+| 3 | VCC | power_in | Supply pin for the device, recommended 6 V to 16 V, with a stabilization capacitor of 1 µF or more connected between VCC and GND using a thick, short pattern. |+| 4 | SENSE | input | Current-limit detection input that limits the current and makes the device enter lower regeneration mode when the pin voltage exceeds 0.2 V; connect to GND if not used. |+| 5 | RMI | input | Minimum-speed setting input with a recommended input range of 0 V to 5 V; connect to 5VREG through a pullup resistor if not used, and insert a current-limiting resistor if the device supply may turn off first when an external supply is used. |+| 6 | VTH | input | Speed-control input for a pulse signal of 20 kHz to 100 kHz (20 kHz to 50 kHz recommended) through a current-limiting resistor, with a recommended input range of 0 V to 5 V; connect to GND for full speed if not used. |+| 7 | CPWM | output | Connection for the PWM basic-frequency capacitor, where 220 pF gives about 30 kHz oscillation; the capacitor must be connected even when speed control is not used because it also carries the current-limit canceling signal. |+| 8 | FG | output | Open-collector rotation-speed output with a maximum voltage of 19 V and a maximum continuous current of 10 mA; it needs a pullup when used and is left open when not used. |+| 9 | IN- | input | Hall-sensor comparator input with about 15 mV hysteresis and a soft-switch section for ±30 mV differential input, where a minimum Hall input of 100 mVp-p is recommended and traces should be kept short. |+| 10 | IN+ | input | Hall-sensor comparator input with about 15 mV hysteresis and a soft-switch section for ±30 mV differential input; a capacitor between IN+ and IN- is recommended to limit noise. |+| 11 | CT | output | Lock-detection capacitor connection with constant-current charge and discharge that locks the drive when the pin rises to 3 V and unlocks when it falls to 1.1 V; connect to GND when lock detection is not used. |+| 12 | S-S | input | Soft-start capacitor connection, where a capacitor between S-S and 5VREG (recommended 0.1 µF to 1 µF) sets the soft-start time, with an absolute maximum voltage of 7 V; connect to GND when soft start is not used. |+| 13 | 5VREG | power_out | 5-V regulator output with a continuous output current limit of -20 mA, used for pullups and for the Hall sensor. |+| 14 | SGND | power_in | System ground for the control-circuit power-supply system. |+| 15 | OUT1N | output | Lower-side (N-channel) driver output with an absolute maximum output voltage of 18 V and a continuous output current limit of -20 mA. |+| 16 | OUT1P | output | Upper-side (P-channel) driver output with an absolute maximum output voltage of 18 V and a continuous output current limit of 20 mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-16 |+| Category | Motor Driver ICs |+| Pins | 16 |++## CAD (KiCad official)++- Symbol: `TMP815PWR`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16 (KiCad packages3D, STEP)+- 3D model files: `tmp815pwr-etched.step` / `tmp815pwr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tmp815pwr.step` / `tmp815pwr.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/tmp815.pdf) (22 pp, sha256 `61080e814dbecc79`, 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.
