Automotive LED driver covers -40°C to 125°C temperature range
Mouser Electronics is now stocking the LP5899-Q1 automotive LED driver from Texas Instruments.
The SPI-compatible device features an internal oscillator for generating the continuous clock required by the LP589x-Q1 family.
This LED driver is AEC-Q100 qualified for automotive applications and ideal for SPI-compatible connectivity in LP5891-Q1 and LP5892-Q1 devices. It enables control of the LP589x-Q1 device family using a standard SPI controller.
The LP589x-Q1 device family includes the LP5891-Q1, a highly integrated, common-cathode LED matrix driver for use in luminous LED panels, local dimming backlights, and other automotive applications.
The LP5899-Q1 LED driver improves system reliability by incorporating fault reporting for the LP589x-Q1 daisy chain and LP5899-Q1 internal operations.
Diagnostic features include open-drain FAULT pin, SPI communication loss detection, CRC for SPI communication, and CCSI data integrity.
The device can drive multiple LED drivers from the LP589x-Q1 family, with the maximum number of cascaded devices determined by the LED driver.
It features an operating temperature range of -40°C to 125°C temperature range, making it a suitable choice for demanding automotive environments.
