is defined as the
time spent to reach the end of the plateau voltage

IR22381Q/IR21381Q HOP/LOP and HOQ/LOQ
pins can be used to configure gate charge circuit.
Fast turn on can be configured using HOP and LOP
pins (up to t
ON1
switching time).
For slower turn on times HOQ and LOQ can be
used.
Current partitioning can be changed acting on the
output resistors.
In particular, shorting HOP to HOQ and LOP to

reports the gate resistance size for two
commonly used IGBTs (calculation made using
typical datasheet values and assuming Vcc=15V).

Output voltage slope
Turn-on gate resistor R

can be sized to control
output slope
(dV

.
While the output voltage has a non-linear
behaviour, the maximum output slope can be
approximated by:

NOTICE
: Turn on time must be lower than T

to
avoid improper desaturation detection and SSD
triggering.
