NOTES:
2. Shutdown between 3.5V and 4.5V.
3. Parametric limits are guaranteed by design, but not tested in production.
4. The drop voltage is caused by VB to VS current flow during switching. See Figure 3.
5. Assuming 3µs switching overlap, time delay use at testing 100µs.
6. External MOSFET ON or OFF.
7. Input and Enable thresholds tested at V_CC = 4.5V and 6.5V, VB = 12V, VS = 0V, IN at 0V, Response RES at 5.0V.
8. The defined values are to be considered as a maximum allowed value. The input stage does not need to have sink or source capability.
9. The recharge path has to withstand transients in the 120V range for approximately 1µs while injector turn off, causing high power dissipation in
the resistor.
