Thermal shut-down (TSD) circuit
TSD comes in effect if the IC junction reaches a rated temperature. It causes the internal reset circuit to
operate, thus turning off the output block. (Only one TSD circuit is mounted on the IC.)
The TSD operating temperature can be set anywhere in a range between 130qC (min) and 170qC (max).
When TSD comes in effect, the currently latched function data is initialized and the output is stopped.
Once the supply voltage drops to or below the POR voltage to shut down the IC, increasing the supply
voltage above the POR reset voltage initializes and restarts the IC.
