TMI · Stepper Motor Driver · SOP-10
TMI8548 from TMI, in a SOP-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 | VCC | power_in | Power-supply voltage pin, with recommended operating supply of 4 to 16 V; a stabilization capacitor is connected between this pin and GND. |
| 2 | IN1 | input | Driving control input for OUT1 (pin 10) and OUT2 (pin 9), used together with IN2; logic L is 0 to 0.4 V and H is 1.5 to 5.5 V, PWM input is allowed, it has a built-in 100 kΩ pull-down, and the IC enters standby when IN1 to IN4 are all low. |
| 3 | IN2 | input | Driving control input for OUT1 (pin 10) and OUT2 (pin 9), used together with IN1; PWM input is allowed and it has a built-in 100 kΩ pull-down resistor. |
| 4 | IN3 | input | Driving control input for OUT3 (pin 8) and OUT4 (pin 7), used together with IN4; PWM input is allowed and it has a built-in 100 kΩ pull-down resistor. |
| 5 | IN4 | input | Driving control input for OUT3 (pin 8) and OUT4 (pin 7), used together with IN3; PWM input is allowed and it has a built-in 100 kΩ pull-down resistor. |
| 6 | GND | power_in | Ground pin, the reference for VCC decoupling and the device. |
| 7 | OUT4 | output | H-bridge driving output; the motor coil is connected between this pin and OUT3 (pin 8). |
| 8 | OUT3 | output | H-bridge driving output; the motor coil is connected between this pin and OUT4 (pin 7). |
| 9 | OUT2 | output | H-bridge driving output; the motor coil is connected between this pin and OUT1 (pin 10). |
| 10 | OUT1 | output | H-bridge driving output; the motor coil is connected between this pin and OUT2 (pin 9). |
