BD6721FS、BD6722FS
When torque off logic is input by the control signal during fixed time (typ.1ms), the lock protection function becomes off.
It is not influenced at the lock protection time and it is possible to restart at once.
Fig.85 PWM signal and lock protection operation＜BD6722FS＞
The lock protection function doesn't work in an input frequency that is slower than 1kHz(typ.) when assuming H level
DUTY≒0% of the PWM input signal.
Input signal that frequency are faster than 2kHz.
4) Output Tr simultaneous ON prevention circuit ＜BD6718FV＞
The capacitor is discharged according to the cycle of hall signal by connecting an external capacitor and resistor to CR
terminal.
When CR terminal voltage is lower than internal reference voltage (2.5V:typ), IC output has a high impedance. High
impedance block in output switching can be changed by changing the capacitance and resistance to be connected to
CR terminal. It allows prevention of simultaneous activation, regardless of switching speed of external Tr.
