VFLK is taken low, Q4 is turned off, and the capacitor connected to the CE pin is charged by a constant current
source, typically 60
A. When the capacitor voltage reaches the internal reference voltage of 1.284 V and VFLK
is low, Q1 is turned off and Q2 is turned on. With Q2 on, VGHM is discharged by the resistor connected to the
RE pin. Once VGHM is discharged to five times VDD, Q2 is turned off and VGHM is high impedance. In the
application of not using this function, connect VDPM, VFLK with high.
