FUNCTION
Power Stage GND.
H-bridge Output Connection. The output stage is a H-bridge formed by four transistors and
four-protection diode for switching applications.
Supply Voltage for Output Stage Input Pin.
Supply Voltage Input Pin.
Setting of the OSC Waveform High Level Voltage. Use a voltage divider from 6VREG to
set OSC waveform high-level voltage.
Setting of the OSC Waveform Low Level Voltage. Use a voltage divider from 6VREG to set
OSC waveform low-level voltage.
Speed Setting. An external voltage into SET pin to set fan speed.
Minimum Speed Setting. Use a voltage divider from 6VREG to set MIN pin voltage for
setting minimum speed.
PWM Signal Input Terminal.
Oscillator Frequency Setting. Connect a capacitor to SGND to set oscillation frequency.
Rotation Speed Output. This is an open-collector output.
Hall Input +. Connect to hell element positive output.
Hall Bias. This is a 1.3V constant-voltage output for hall element bias.
Hall Input -. Connect to hell element negative output.
Shutdown Time and Restart Time Setting. Connect a capacitor to SGND to set shutdown
time and restart time in lock mode.
6V Regulator Output. This is a 6V constant-voltage output for application circuit biases.
Control Stage GND.
H-bridge Output Connection. The output stage is a H-bridge formed by four transistors and
four-protection diode for switching applications.
Power Stage GND.
Power Stage GND.
