Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PWM | input | PWM speed control input with an internal 10kΩ pull-up, VIL 0 to 0.4V and VIH 2.1 to 5.5V, with a PWM input frequency of 0.1 to 100kHz; absolute maximum PWM input voltage is 7V. |
| 2 | FG/RD | output | Open-drain frequency generation / rotation detect output that must use an external pull-up, with an absolute maximum output voltage of 18V and output current of 30mA. |
| 3 | OUT1 | output | H-bridge output 1 connected to one end of the single coil, with absolute maximum peak output current of 1000mA and continuous output current of 450mA. |
| 4 | VDD | power_in | Supply pin with a recommended operating range of 3.5V to 18V and an absolute maximum supply voltage of 21V. |
| 5 | OUT2 | output | H-bridge output 2 connected to the other end of the single coil, with absolute maximum peak output current of 1000mA and continuous output current of 450mA. |
| 6 | GND | power_in | Ground pin of the chip; no series components such as 0Ω resistors or magnetic beads may be placed in the GND circuit. |
| 7 | MINSP | input | Minimum speed setting input with an effective voltage range of 0 to 2.5V and an absolute maximum input voltage of 7V. |
| 8 | VREF | power_out | Internal reference voltage output of 2.45V to 2.55V, which requires a capacitor greater than 1uF to ground for loop stability. |
