Short-circuit protection

The TS2007 includes an output short-circuit protection. This protection prevents the device

from being damaged if there are fault conditions on the amplifier outputs.

When a channel is in operating mode and a short-circuit occurs directly between two

outputs (Out+ and Out-) or between an output and ground (Out+ and GND or Out- and

GND), the short-circuit protection detects this situation and puts the amplifier into standby.

To put the amplifier back into operating mode, put the standby pin to logical LO and then to

logical HI.

Thermal shutdown

The TS2007 device has an internal thermal shutdown protection in the event of extreme

temperatures to protect the device from overheating. Thermal shutdown is active when the

device reaches 150°C. When the temperature decreases to safe levels, the circuit switches

back to normal operation.
