ZHCSIO0A December 2017 – August 2018 TLC6C5724-Q1
PRODUCTION DATA.
The TLC6C5724-Q1 device supports an active-low open-drain error output. Figure 24 shows the error pulldown block diagram. 10-bit error status information controls the error pulldown circuit directly. But LED failure can be masked by the LED_ERR_MASK bit. The LED_ERR_MASK value is 1 by default, so an LED failure is masked from the error pulldown circuit. Even if there is an LED failure, the ERR pin is not pulled down by this LED failure. If LED_ERR_MASK is 0, the ERR pin is pulled down by an LED failure to indicate an error scenario. Users can use an MCU interrupt to read out the fault information.
