Short circuit trip level
Over current trip level
Protection is achieved by monitoring and filtering the N-side
DC-Bus current. When a current trip-level is exceeded, all the N-
side IGBTs are intercepted (turned OFF) and a fault-signal is out-
put. After the fault-signal output duration (1.8msec (typ.)@ 25°C),
the interception is Reset at the following OFF input signal level
(more than 4.0V).

Description:
(1) During the ON-State of either of the upper-arm or the lower-arm IGBT, the inter-lock protection circuit blocks any erroneous ON pulses (re-
sulting from input noise) from triggering the other arm IGBT and thus it prevents the arm-shoot-through situation.
(2) When two ON-signals are received for both the upper and the lower arms, the signal received first will be passed to the IGBT and the sec-
ond signal will be blocked. The second signal will be passed to its corresponding IGBT immediately after the first signal is OFF.
Note: This protective function provides no fault signaling output.
Operation:
a1. P-side normal ON-signal ⇒ P-side IGBT gate turns ON.
a2. N-side erroneous ON-signal ⇒ N-side IGBT gate remains OFF.
a3. While P-side ON-signal remains ⇒ P-side IGBT gate remains ON.
a4. N-side normal ON-signal ⇒ N-side IGBT gate turns ON.
b1. N-side normal ON-signal ⇒ N-side IGBT gate turns ON.
b2. Simultaneous ON-signals ⇒ P-side IGBT gate remains OFF.
b3. N-side receives OFF-signal ⇒ N-side IGBT gate turns OFF.
b4. Immediately after (b3) ⇒ P-side IGBT gate turns ON.
