Description
General part information
MAX25503 Series
The MAX25503 is a 4 x 24-channel modular matrix driver. The integrated current outputs can sink up to 65mA 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 high-speed interface can be used to control up to 16 devices.The MAX25503 is available in TQFN and TSSOP packages and operates in the -40°C to +125°C temperature range.APPLICATIONSCentral Information DisplaysInstrument ClustersInterior LightingExterior Rear Lighting
