Figure 3. Power Protection Block Diagram
In fig. 3 there is the power protection strategy pictures. Under the curve of the 32W power, the chip is in normal
operation, over 60W the chip is forced in Standby. This last status would be reached if the digital converter does
not respond quikly enough reducing the stress to less than 60W.
The fig.4 gives the protection current, Iprot, behavior. The current sourced by the pin Prot follows the formula:
for P

< P

the I

= 0
Independently of the output voltage, the chip is also shut down in the folowing conditions:
When the currentthrough the sensing resistor, R
sense
, reaches 7A (Voltage drop (CD+) - (CD+1) = 700mV).
When the average junction temperature of the chip reaches 150°C.
When the ground potential differ from more than 5V from the half of the power supply voltage, ((CD+)-(CD-))/2
When the sum of the supply voltage

|Vs-| <20V
The output bridge is muted when the average junction temperature reaches 130°C.
