4.4

Active Miller clamp

avoid the use of a negative supply voltage.

During turn-off, the gate voltage is monitored and the clamp output is activated when gate

voltage goes below 2 V (relative to GND). The clamp is disabled when the IN input is

triggered again.

4.5

Fault status output

Fault output is used to signal a fault event (desaturation, UVLO) to a controller. The fault pin

is designed to drive an optocoupler.

4.6

Undervoltage protection

Undervoltage detection protects the application in the event of a low VH supply voltage

(during start-up or a fault situation). Fault output signals the undervoltage state and is reset

only when undervoltage state disappears.
