7. OPERATIONAL MODE SELECTION
The FAN8902 has three operation modes as follows:
- STOP: Turned-off the power MOSFET
- LINEAR: Linearly controlled the power MOSFET
- FULL-ON: Fully turned-on the power MOSFET
The voltage, V
SRT (PIN #9)
and V
MAX (PIN #7)
, in the application circuit are as follows:
- V
SRT (PIN #9)
= Vref
×
R7 / (R5 + R6 + R7)
- V
MAX (PIN #7)
= Vref
×
(R6 + R7) / (R5 + R6 + R7)
8. OVER VOLTAGE PROTECTOR (OVP)
If the voltage, V
BAT
≥
36[V], the output (pin #12) is grounded, and the switching device (power MOSFET) is turned-off, and
the motor is stopped. Then if the voltage, V
BAT
→
36[V], the switching device is turned-on again, and the motor is operated.
9. TOTEM-POLE OUTPUT
The FAN8902 has a single totem-pole output driver which can be drive current to peak
±
0.8[A].
