SHORT-CIRCUIT PROTECTION
TPA3200D1

The TPA3200D1 has short circuit protection circuitry on the outputs that prevents damage to the device during
output-to-output shorts, output-to-GND shorts, and output-to-VCC shorts. When a short-circuit is detected on the
outputs, the part immediately disables the output drive and enters into shutdown mode. This is a latched fault
and must be reset by cycling the voltage on the SHUTDOWN pin to a logic low and back to the logic high state
for normal operation. This will clear the short-circuit flag and allow for normal operation if the short was removed.
If the short was not removed, the protection circuitry will again activate.
Two Schottky diodes are required to provide short-circuit protection. The diodes should be placed as close to the
TPA3200D1 as possible, with the anodes connected to PGND and the cathodes connected to OUTP and OUTN
as shown in the application circuit schematic. The diodes should have a forward voltage rating of 0.5 V at a
minimum of 1 A output current and a dc blocking voltage rating of at least 30 V. The diodes must also be rated to
operate at a junction temperature of 150°C.
If short-circuit protection is not required, the Schottky diodes may be omitted.
