TMI8340SP-MS from MSKSEMI, in a SOP-8. 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 | BI | input | Reverse-direction logic input (BI=H with FI=L drives reverse); VIH min 2.2 V, VIL max 0.7 V, input voltage range -0.3 V to 6.5 V, and it must stay low or high-impedance until 3 ms after VCC power-up. |
| 2 | FI | input | Forward-direction logic input (FI=H with BI=L drives forward); VIH min 2.2 V, VIL max 0.7 V, input voltage range -0.3 V to 6.5 V, and it must stay low or high-impedance until 3 ms after VCC power-up. |
| 3 | GND | power_in | Ground terminal to which all device voltage values are referenced. |
| 4 | VCC | power_in | Motor and logic supply input with recommended operating range 3 V to 30 V (absolute maximum 33 V), decoupled with input capacitors placed close to the pin. |
| 5 | FO | output | Forward H-bridge output (H in forward mode, L in brake, open in stop) with recommended continuous output current up to 6.0 A. |
| 6 | FO | output | Forward H-bridge output, paired with pin 5 (H in forward mode, L in brake, open in stop) with recommended continuous output current up to 6.0 A. |
| 7 | BO | output | Reverse H-bridge output (H in reverse mode, L in brake, open in stop) with recommended continuous output current up to 6.0 A. |
| 8 | BO | output | Reverse H-bridge output, paired with pin 7 (H in reverse mode, L in brake, open in stop) with recommended continuous output current up to 6.0 A. |
