NOTES

1)

Excluding situations where the over current protection is active.

2)

The non oscillation current is specified in a temperature range

of 0 to 100 0C. For Tj < 0 0C and Tj > 100 0C the maximum

start-up current is 350 mA.

3)

Data sampling of VCS(ph) is performed at the end of

conduction of T2.

4)

Gain is defined as ICT/ICS with VCS>VCS(clamp).

5)

Total supply current is specified in a Tj temperature range of -

20 0C to 125 0C at fB, excluding gate drive charge.

6)

Data sampling of VCS(cap) is performed at the start of

7)

conduction of T2.

8)

The symmetry SYM fB is calculated from the quotient SYM fB

= T1tot/T2tot, with T1tot the time between turn-off of G2 and

the turn-off of G1, and T2tot the time between turn-off of G1

and the turn-off of G2.

9)

Not measured, guaranteed by design.

10) The symmetry SYM TNO is defined as the ratio between

deadtime1 and deadtime2. Deadtime1 is the time between

turning off G1 and turning on G2. Deadtime2 is the time

between turning off G2 and turning on G1.

11) Preheat & ignition states.
