Recovery From Error
Interchannel Delay (ICD) Settings
www.ti.com............................................................................................................................................. SLOS606D – MARCH 2009 – REVISED SEPTEMBER 2009
Protection Mechanisms in the TAS5706A/B
SCP (short-circuit protection, OCP) protects against shorts across the load, to GND, and to PVCC.
OTP turns off the device if T
die (typical) > 150°C.
UVP turns off the device if PVCC (typical) < 8.4 V
OVP turns off the device if PVCC (typical) > 27.5 V
A short-circuit condition can be detected also by an external controller. The SCP error from the external power
stage is also fed into TAS5706A/B. The VALID pin goes low in the event of a short circuit. The VALID pin can be
monitored by an external
C. The TAS5706A/B initiates a back-end error sequence by itself to recover from the
error, which involves settling VALID low for a programmable amount of time and then retrying to check whether
the SCP condition still exists.
OTP turns on the device back when T
die(typical) < 135°C.
UVP turns on the device if PVCC (typical) is > 8.5 V.
OVP turns on the device if PVCC (typical) is < 27.2 V.
