has to be long enough to charge the capacitor.
The bootstrap driver introduces a voltage drop due to the DMOS RDSON (typical value: 125 Ohm). At low fre-
quency this drop can be neglected. Anyway increasing the frequency it must be taken in to account.
The following equation is useful to compute the drop on the bootstrap DMOS:
where Q
gate
is the gate charge of the external power MOS, R
dson
is the on resistance of the bootstrap DMOS,
and T
charge
is the charging time of the bootstrap capacitor.
For example: using a power MOS with a total gate charge of 30nC the drop on the bootstrap DMOS is about
1V, if the T
charge
is 5
μ
s. In fact:
V
drop
has to be taken into account when the voltage drop on C
BOOT
is calculated: if this drop is too high, or the
circuit topology doesn't allow a sufficient charging time, an external diode can be used.
