NOTES:
1 Guaranteed by design but not tested. Typical parameters are representative of actual device
performance but are for reference only.
2 ±Vcc=+15V, V+=28V unless otherwise specified.
3 This is to be used for MOSFET thermal calculation only.
4 Measurements do not include offset current at 0V current command.
5 Continuous operation at or above absolute maximum ratings may adversly effect the device performance
and/or life cycle.
6 When applying power to the device, apply the low voltage followed by the high voltage or alternatively, apply both at the
same time. Do not apply high voltage without low voltage present.
