Description

The MAX8904 evaluation kit (EV kit) is a fully assembled and tested PCB that evaluates the MAX8904 power-management IC. The MAX8904 EV kit operates from an input supply range of 3.4V to 13.2V and is controlled by an I²C interface. The MAX8904 includes five step-down converters (1V2, 1V8, 3V3, 5V0, and ADJ), a WLED step-up converter (BST), a current-limited switch (CLS), a current-sense amplifier (CSA) with differential inputs, an active-low open-drain comparator (CMP), and an 8-bit GPIO port. The MAX8904 also controls an external n-MOSFET for input overvoltage protection (13.5V, typ) and an external p-MOSFET for reverse-polarity protection (up to -28V) of downstream circuits. The I²C interface supports output-voltage setting of the ADJ power rail and BST regulator (voltage-source mode), WLED current setting for the BST regulator (WLED current regulator mode), GPIO control, and enable/disable of ADJ, 5V0, BST, CSA, CMP, and CLS blocks.

The MAX8904 EV kit also includes Windows® 2000-, Windows XP®-, and Windows Vista®-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the MAX8904. To evaluate the MAX8904, order the MINIQUSB+ command module along with the MAX8904 EV kit.
