1.3Short-Circuit Protection and Fault Reporting Circuitry

The TAS5110 is a self-protecting device that provides device fault reporting (including over-temperature protect and short-circuit protection).

1.3.1Device Fault Reporting

The ERR0, ERR1, and SHUTDOWN outputs from TAS5110 indicates the device conditions shown in Table 1–1. The device fault reporting outputs are open-drain outputs.

1.3.2Short-Circuit Protection

The short-circuit protect error condition latches the TAS5110 in the shutdown mode:

-H-bridge outputs (OUTPUTA and OUTPUTB) are in a high-impedance state (Hi-Z state).

-SHUTDOWN is asserted low.

-ERR0 is high and ERR1 is asserted low.

-The H-bridge outputs remains in a Hi-Z state until the device is reset (RESET pin asserted low).

The TAS5110 is not designed for driving load impedance less than 4 Ω (at 20-Vdc output stage supply), where the internal current limit protection is activated at high power levels.

1.3.3Auto Recovery System

Together with a PWM processor from Texas Instruments (e.g., the TAS5026 or the TAS5036), the TAS5110 can be configured in autorecovery mode. The SHUTDOWN signal from the TAS5110 is in autorecovery mode connected to ERR_RCVY at the PWM processor.

The short-circuit protect error condition results in the following autorecovery sequence:
