THERMAL SHUTDOWN (TSD)
• Basic Operation
• Functional Description
When the junction temperature (chip temperature) is equal to or lower than the TSD threshold, output signals
are controlled by input signals. However, when the junction temperature exceeds the threshold, output pins
are put into a high-impedance state regardless of input signals.
Temperature sensing is performed by monitoring the V
compared to the internal reference voltage, the TSD circuit sends a signal to the control logic to turn off the
output transistors. Otherwise, the control logic is controlled by the IN1 and IN2 inputs.
