4, the VGHM pin is driving a purely capacitive load, 4.7nF.
The value of resistor R1 is 15kohm, R2 is 1.1k
and R3 is
750
. In both transient plots, there is no C
E delay capacitor.

FIGURE 4.
In the GPM block diagram, a signal called “Reset” is shown.
This signal is generated from the V
IN under-voltage lockout,
thermal shutdown, or the SHDN pin. If the V
IN supply voltage
drops below 2.3V, typically, then the GPM block will be dis-
abled and the VGHM pin will discharge through NMOS switch
N2 and the 1k
resistor. This applies also if the junction tem-
perature of the device exceeds 145°C or if the SHDN signal
is low. As shown in the block diagram, both VDPM and VFLK
have internal 350k
pull down resistors. This puts both VDPM
and VFLK in normally “off” states. Typical VDPM and VFLK
pin currents can be found in the Typical Performance Char-
acteristics section.
