Texas Instruments TLC69699/TLC69699-Q1 LED Drivers

Texas Instruments TLC69699/TLC69699-Q1 LED Drivers provide SPI-compatible connectivity for the TLC696xx/TLC696xx-Q1 device family, which is controlled using a standard SPI controller. These drivers incorporate reporting of faults in both the TLC696xx/TLC696xx-Q1 daisy chain and TLC69699/TLC69699-Q1 internal. The data transmission of register and brightness to the TLC696xx/TLC696xx-Q1 daisy chain is CRC-protected by TLC69699/TLC69699-Q1. This transmission includes the data and continuous clock lines that TLC69699/TLC69699-Q1 guards for stuck-at faults. The TLC69699/LC69699-Q1 LED drivers operate at 2.5V to 5.5V voltage VCC range. These LED drivers support multiple peripherals with one controller and up to 20MHz transfer data frequency. The TLC69699/TLC69699-Q1 LED drivers are ideal for SPI-compatible connectivity for TLC696x0/1/2/4/8Q1 devices. The Texas Instruments TLC69699-Q1 devices are AEC-Q100 qualified for automotive applications.
