9.22.3 Under Voltage / Thermal Error State (UVTE[1:0])

Function:

Indicates the operational status of the amplifier. These bits can identify a Thermal Warning condition, a

Thermal Error condition, or an Under Voltage condition. The thresholds for each of these conditions is

listed in the PWM Power Output Characteristics table on page 20.

UVTE[1:0] Setting

Under Voltage & Thermal Error Status

00 ........................................ The device is operating normally.

01 ........................................ The device is operating normally; however a Thermal Warning condition is being reported.

10 ........................................ An Under Voltage condition is currently present.

11......................................... A Thermal Error condition is currently present.
