Note 1: These protection functions are only a means of temporarily avoiding some output short circuits or other
abnormal conditions and are not guaranteed to prevent damage to the IC.
Note 2: If used under conditions where the absolute maximum ratings are exceeded, the IC may break down before
the protection circuits start operating.
Overheat Protection (TSD)
● Basic operation
The input signal of the IC controls the output while the junction temperature (chip temperature) of the IC
is equal to or lower than the TSD detection temperature. If the junction temperature becomes higher than
the TSD detection temperature, the output enters a high-impedance state regardless of the level of the input
signal.
● Explanation of the operation
The junction temperature is detected by monitoring the VF of a diode on the chip. When the VF becomes
lower than the internal reference voltage, the control logic is directed to turn off the output transistor. While
the VF is higher than the reference voltage, the input signal at pins 1 and 2 controls the logic section.
