MAX25500AUMA/V+T

Price range: $3.25

The MAX25500 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 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. The 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, multiplex ratio, etc. The device features a high-speed SPI for control using a daisy-chain. 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
