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.
