# DRV110APWR

**Texas Instruments** · Relay / Coil Drivers · TSSOP-14

DRV110APWR from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | KEEP | input | Keep time set. External capacitor to GND programs the duration the device stays in peak-current mode before transitioning to hold mode. |
| 2 | PEAK | input | Peak current set. External resistor to GND sets the solenoid peak current threshold reference used during the initial pull-in phase. |
| 3 | OSC | input | PWM frequency set. External resistor to GND programs the internal PWM oscillator frequency (typ. R_OSC 50 kΩ to 160 kΩ range). |
| 4 | VIN | power_in | 6 V to 15 V supply input. Powers the device; internal Zener clamps VIN to V_ZENER so it can be fed from higher rails through an external series resistor R_S. |
| 5 | GND | power_in | Device ground. All voltages are referenced to this pin. |
| 6 | SENSE | input | Solenoid current sense input. Connects to the external low-side R_SENSE resistor to monitor the solenoid current for peak/hold regulation. |
| 7 | OUT | output | Solenoid switch gate drive. Drives the gate of the external N-channel MOSFET that switches the solenoid current. Rated up to 20 V. |
| 8 | EN | input | Enable input. Logic-level control that turns the device on/off; also participates in UVLO behavior. |

## CAD (KiCad official)

- Symbol: `DRV110APWR`
- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`
- 3D model: TSSOP-14 (KiCad packages3D, STEP)
- 3D model files: `drv110apwr-etched.step` / `drv110apwr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `drv110apwr.step` / `drv110apwr.glb` are the bare package body.
