Pin Functions

PIN I/O DESCRIPTION
NO. NAME
1 FG Output Motor speed indicator output (open drain).
2 FGS Input Motor speed indicator selector. The state of this pin is latched on power up and can not be changed dynamically.
3 VCC Power Input voltage for motor and chip supply.
4 W IO Motor Phase W
5 GND Ground Ground
6 V IO Motor Phase V
7 U IO Motor Phase U
8 FR Input Motor direction selector. This pin can be dynamically changed after power up.
9 CONFIG Input Resistor setting for configuring the handoff threshold. The state of this pin is latched on power up and can not be changed dynamically.
10 PWM Input Motor speed control input.
— Thermal Pad — Connect to Ground for maximum thermal efficiency. Thermal pad is on the bottom of the package.
