製品詳細

The MAX25500 evaluation kit (EV kit) demonstrates the MAX25500 and the MAX25501, 4x24-channel modular matrix backlight drivers with ASIL B features (MAX25501 only) for use with local-dimming automotive displays.

The EV kit operates from a DC supply voltage between 3V and 5V (VCC) while the on-board 4x48 LED matrix can be powered either from the on-board MAX20077 buck converter, the on-board MAX20048 buck-boost converter or from an external power supply connected to VLED. The EV kit can be configured to operate alone or with other MAX25500 EV kits in a daisy-chain or star connection.

The EV kit also demonstrates short-LED (this includes SNK_ to SNK_, SRC_ to VLED, SRC_ to GND shorts), open-LED, VLED Undervoltage and Overvoltage and overtemperature-fault protection.

The EV kit provides an SPI interface that can operate in conjunction with the MINIQUSB+ adapter board or a thirdparty SPI master. The EV kit also includes Windows®- compatible software that provides a simple graphical user interface (GUI) for exercising the features of the IC.

Note: Eight different EV kit versions exist, each designed to accommodate one of the two available MAX25500/ MAX25501 IC packages (TQFN and TSSOP), featuring one of the two available SPI control interfaces (Daisychain and Star). The instructions given in the following paragraphs equally apply to all the EV kit versions. See the Ordering Information table at the end of this document for details on the different EV kits.
