The MAX25501 is a 4 x 24-channel modular matrix backlight driver for use with local-dimming automotive displays. The integrated current outputs can sink up to 72mA LED current each. The source drive pins provide current to the columns of the matrix on a multiplexed basis. Device power comes from an external 3.3V or 5V supply, while the LED current-sink outputs can operate at up to 14V.A feedback output pin (FB) is provided to control an external DC-DC converter so that voltage headroom can be optimized and the overall system power dissipation reduced.The device is highly flexible due to its programmability using the SPI interface. Among the programmable parameters are the LED current, individual PWM settings, and multiplex ratio.The MAX25501 includes multiple diagnostic features to aid in the building of ASIL B systems.The device features a high-speed SPI interface for control using a daisy-chain or star configuration. Up to 16 devices can be daisy-chained to reduce connection complexity.The MAX25501 is available in TQFN and TSSOP packages and operates in the -40°C to +125°C temperature range.
