4.6

Power-Outputs 8 - 11 (Lamp drivers)

Outputs 8 - 11 are a high-side switches intended to drive ohmic loads 5W or 10W lamp

(bulb) loads.

Protection and Diagnosis

4.6.1.1

Short Circuit of Output to Ground

The high-side switches are protected against short to GND.

The high-side switches Out 8 - 11 are protected against short to GND.

Short Circuit during switch-on

During switch-on of an output a current an voltage level is used to check for a short

circuit. If a switch is turned on and the short circuit condition is valid after

dSDon8 the

output transistor is turned off and the corresponding diagnosis bit is set. A short circuit

condition is valid if the current rises above the shutdown threshold

SD8 and the voltage

at the output stays below VSD8. During the delay time, the current is limited to ISC8 as

shown in Figure 16
