NOTES:
2. Ensured by design, not production tested.
4. The pulldown (sink) circuit of the high-side driver is a MOSFET transistor referenced to DRVGND. The driver circuits are bipolar
and MOSFET transistors in parallel. The peak output current rating is the combined current rating from the bipolar and MOSFET
transistors. The output resistance is the rds(on) of the MOSFET transistor when the voltage on the driver output is less than the
saturation voltage of the bipolar transistor.
5. Rise and fall times are measured from 10% to 90% of pulsed values.
