Description
General part information
MAX25500 Series
The MAX25500 is a 4 × 24-channel modular matrix backlight driver for use with local-dimming automotive displays. The integrated current outputs can sink up to 72mA Light Emitting Diode (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 reThe device is highly flexible due to its programmability using the serial peripheral interface (SPI). Among the programmable parameters are the LED current, individual pulse-width modulation (PWM) settings, and multiplex ratio.The device features a high-speed SPI for control using a daisy-chain or star configuration. Up to 16 devices can be daisy-chained to reduce connection complexity.The MAX25500 is available in TQFN and TSSOP packages, and operates in the −40°C to 125°C temperature range.ApplicationsCentral Information DisplaysInstrument ClustersInterior Lighting
