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.
4.6.1
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
t
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
I
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
