TLE 6244X

3.7.8.5 Maximum

Clamping En-

ergy at Load

Dump

For a maximum of 10 times during

ECU life (load dump with 400ms

and Ri = 2Ω over the load, e.g. 2W

lamp)

3.7.8.6 Jump Start

Each output 150% of the values of

3.7.8.3.

For a maximum of 10 jump starts

of 2 minutes each during ECU life.

3.7.8.7Singlepulse

TC ≤ 60°C

IOUT15, 16 ≤ 0.6A, max 10 000

pulses

3.8 Power Outputs

1.1A/45V

OUT7,8,

OUT17,18

In case of open input (parallel con-

trol) or missing power supply the

power stage is switched off. Paral-

lel connection of power stages is

possible.

For OUT7, OUT8

Above this limit short circuit to

UBatt is detected. For the duration

of the shutoff delay time tVoff (see

3.8.4) the output current is limited

to approximately this value. If the

short circuit condition is still

present after tVoff, the outputs

OUT7/8 are switched off. An error

is stored after tDiag (see 3.11.4).

The same is true for OUT17

OUT18 if the static current limita-

tion is not enabled.
