SA8337-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 with VIH of at least 2.2 V and VIL of at most 0.7 V; it must stay low or high-impedance until VCC has been applied for 3 ms (tD), and its frequency must not exceed 30 kHz. |
| 2 | FI | input | Forward-direction logic input with VIH of at least 2.2 V and VIL of at most 0.7 V; it must stay low or high-impedance until VCC has been applied for 3 ms (tD), and its frequency must not exceed 30 kHz. |
| 3 | GND | power_in | Ground terminal; all absolute maximum and electrical voltages are referenced to this pin. |
| 4 | VCC | power_in | Motor and logic supply input with an operating range of 3 V to 18 V and an absolute maximum of 20 V, decoupled close to the pin with the recommended capacitors. |
| 5 | FO | output | Forward H-bridge motor output, high in forward mode and low in reverse or brake mode, rated for a continuous output current of 5.0 A (9.0 A absolute maximum). |
| 6 | FO | output | Forward H-bridge motor output, high in forward mode and low in reverse or brake mode, rated for a continuous output current of 5.0 A (9.0 A absolute maximum). |
| 7 | BO | output | Reverse H-bridge motor output, high in reverse mode and low in forward or brake mode, rated for a continuous output current of 5.0 A (9.0 A absolute maximum). |
| 8 | BO | output | Reverse H-bridge motor output, high in reverse mode and low in forward or brake mode, rated for a continuous output current of 5.0 A (9.0 A absolute maximum). |
