ST-PLC-AFE

System timings and interruptions

9.3.2

Over temperature condition

The ST-PLC-AFE contains protective, internal circuitry that automatically disables the PA

output stage if the junction temperature exceeds 160 °C. The device also includes a thermal

hysteresis which allows the PA to resume normal operation when the junction temperature

falls to 145 °C.

If a fault condition occurs that causes a thermal overload, the T_FLAG bit switches from 0 to

1. This configuration results in an interrupt signal at the INT pin. The T_FLAG bit remains

set to 1 even after the device returns to normal operation. The T_FLAG bit remains 1 until it

is reset by the microprocessor (when 0 is written inside the T_FLAG bit of the Status

operation.
