Dynamic Electrical Characteristics
Unless otherwise noted, these specifications apply for an operating junction temperature range of -40°C ≤ Tj ≤ 125°C with bias conditions of
VPR = VBS = 15V, VS1,2,3 = VSS = COM, and CL = 1000 pF.

Normal Operation: An anti-shoot-through
logic prevents each channel from turning on
simultaneously the HS and LS switches
Over-current detection (FLT)

* Not recommended (cycling on default)
Note 3: The proper sequence to reset the Fault latch is to first set EN at 0V and then cycle the FRST pin. The gate drives return to normal
operation when EN is set again at 5V.
