**HTCSEMI** · Brushed DC Motor Drivers · MSOP-10

HT8827ARMZ from HTCSEMI, in a MSOP-10. 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 | VDD | power_in | Power supply pin; the datasheet specifies VDD of 2.0 V min, 3 V typ and 5.5 V max, with absolute maximum rating 5.5 V. |
| 2 | IN4 | input | Input pin that determines the driving mode; the datasheet gives VIH of 0.5*VDD to VDD+0.4 V and VIL of -0.4 V to 0.2*VDD. |
| 3 | IN3 | input | Input pin that determines the driving mode; the datasheet gives VIH of 0.5*VDD to VDD+0.4 V and VIL of -0.4 V to 0.2*VDD. |
| 4 | IN1 | input | Input pin that determines the driving mode; the datasheet gives VIH of 0.5*VDD to VDD+0.4 V and VIL of -0.4 V to 0.2*VDD. |
| 5 | IN2 | input | Input pin that determines the driving mode; the datasheet gives VIH of 0.5*VDD to VDD+0.4 V and VIL of -0.4 V to 0.2*VDD. |
| 6 | GND | power_in | Ground pin. |
| 7 | O2 | output | Output sinking / driving pin; maximum output current is 400 mA per channel for the MSOP and DFN packages. |
| 8 | O1 | output | Output sinking / driving pin; maximum output current is 400 mA per channel for the MSOP and DFN packages. |
| 9 | O3 | output | Output sinking / driving pin; maximum output current is 400 mA per channel for the MSOP and DFN packages. |
| 10 | O4 | output | Output sinking / driving pin; maximum output current is 400 mA per channel for the MSOP and DFN packages. |

## CAD (KiCad official)

- Symbol: `HT8827ARMZ`
- Footprint: `Package_SO:MSOP-10_3x3mm_P0.5mm`
- 3D model: MSOP-10 (KiCad packages3D, STEP)
- 3D model files: `ht8827armz-etched.step` / `ht8827armz-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ht8827armz.step` / `ht8827armz.glb` are the bare package body.
