Application Information
1. Lock Detection & Automatic Restart
FAN8404D features a lock detection and an automatic restart. The functions can be operated as follows.
1) When the hall signal stop switching, a motor can be locked.
2) The voltage, V
LD
on pin 3, is increasing until it reaches V
LDCL
.
3) When the voltage, V
LD
reaches V
LDCL
, the alarm output (AL) becomes high as a motor lock has been detected.
4) If LD pin is connected to GND, the lockup protection is disabled.
5) While a motor is locked, the output repeats switching ON / OFF, but the other output is always OFF. The switching time can
be determined by an external capacitor on charging / discharging time of the capacitor, switching ON / OFF time can be
calculated as follows.
Where, The C
LD
is an external capacitor connected to pin 3, LD.
The V
LDCL
is the clamp voltage on pin 3, LD.
The V
LDCP
is the comparator voltage on pin 3, LD.
The I
LDC
is the charging current on pin 3, LD.
The I
LDD
is the dischaging current on pin 3, LD.
2. Thermal Shut Down
TSD On: All the outputs are off.(Typ. 175
