Thermal protection circuit
This circuit detects the temperature (150
°C or more) inside LSI for protection. While this protection circuit is active,
the output Tr is turned OFF on both high- and low-sides, putting the output in the high-impedance state. This operation
is also provided with the hysteresis.
Supply voltage drop protection circuit
To avoid unstable operation at low voltages, this circuit monitors the PVD pin voltage and turns ON the amplifier when
this voltage exceeds the Attack voltage (VD = 7V typ.). In addition, to avoid unstable operation when the PVD pin
voltage has dropped because of certain reasons, the Recover voltage (VD = 6V typ.) is set. Both Attack and Recover
voltages have the hysteresis (about 1V) to prevent continuous ON / OFF operation of the supply voltage drop
protection circuit.

Output offset detection protection circuit
This circuit is a protection circuit intended to alleviate burn of the loudspeakers when DC outputs to the BTL output for
a certain period or more.
The circuit detects the case in which each BTL input of each channel continues to disagree (for about 300ms), turns
OFF the output Tr on both high- and low-sides, and puts the output in the high-impedance state.
