Datasheet
● Description of operations
1) Lock protection and automatic restart
Lock detection ON time (Ton) and lock detection OFF time (Toff) is set by charging and discharging of
external capacitor of LD terminal.
Ton (Lock detection ON time) =
Toff (Lock detection OFF time) =
H-
C ? (Vldcl-Vldcp)
Ildc
C ? (Vldcl-Vldcp)
Ildd
C : Capacity of capacitor equipped
externally on LD terminal
Vldcl : LD terminal clamping voltage
Vldcp : LD terminal comparator voltage
Ildc : LD terminal charging current
Ildd : LD terminal discharging current

Fig.7 Lock protection timing chart
*BA6424AFS returns normal operation by the input of hall signal during Toff.
2) Hall input setting
Hall input voltage range is shown in operating conditions.

Fig.8 Hall input voltage range
Adjust the value of hall element bias resistor R1 in Fig.9 so that the input voltage of a hall amplifier is input in "hall
input voltage range" including signal amplitude.
