ZHCSFY2B August 2015 – February 2019 TAS2555
PRODUCTION DATA.
The TAS2555 device has an integrated overcurrent protection that is enabled once the Class-D is powered up. A fault on the Class-D output causing a large current in the range of 3 A to 5 A triggers the overcurrent fault. Once the fault is detected the TAS2555 device disables the audio channel and power down the Class-D amplifier. When an over-current event occurs, a status flag at B0_P0_R104[7] is set. This register is sticky and the bit remains high for as long as it is not read, or the device is not reset. The overcurrent event can also be used to generate an interrupt if required. Refer to "IRQ and flags" section for more details. To re-enable the audio channel after a fault the Class-D the device must be hardware or software reset and the TAS2555 configuration must be re-loaded.
