Output Stage Protection
The output stage is protected against overvoltage, short
circuit and thermal runaway conditions (Figure 1).
Figure 1. Typical Circuit Waveforms for Output Stage Protection.
If the input voltage rises above 30V (e.g. load dump), the out-
put shuts down. This response protects the internal circuitry
and enables the IC to survive unexpected voltage transients.
Should the junction temperature of the power device exceed
180C (typ) the load current capability is reduced thereby
preventing thermal overload. This thermal management
function is an effective means to prevent die overheating
since the load current is the principle heat source in the IC.
The CS8101 contains two microprocessor compatible con-
trol functions:
