the high-impedance state. When the supply voltage recovers to within the operating range
the device restarts.
Overcurrent protection (OCP)
If the output current exceeds the value for IOCP given in Table 5: Electrical specifications on
page 8 the overcurrent protection is activated which forces the outputs to the
high-impedance state. Periodically, the device attempts to restart. If the overcurrent
condition is still present then the OCP remains active. The restart time, TOC, is determined
by the R-C components connected to pin STBY.
Thermal protection (OTP)
If the junction temperature, Tj, reaches 145 °C (nominal), the device goes to mute mode and
the positive and negative PWM outputs are forced to 50% duty cycle. If the junction
temperature exceeds the value for Tj given in Table 5: Electrical specifications on page 8 the
device shuts down and the output is forced to the high impedance state. When the device
cools sufficiently the device restarts.

Diagnostic output
The output pin DIAG is an open drain transistor. When the protection is activated it is in the
high-impedance state. The pin can be connected to a power supply (< 26 V) by a pull-up
resistor whose value is limited by the maximum sinking current (200 A) of the pin.
