The MAX1785 evaluation kit (EV kit) demonstrates the capabilities of the MAX1785 advanced smart battery-pack controller. The EV kit includes multiple component networks to utilize the functionality of the Port A (PA) I/O, high-voltage (HV) outputs, SMBus™ interface, and battery-cell terminals. Each network can be configured to provide proper evaluation of the programmed device.
Integrated into the EV kit design is a MAX1906X battery-pack protection circuit that provides overvoltage protection and disconnected-cell detection. The MAX1906X IC works in conjunction with the MAX1785 IC to provide added functionality to the battery-pack controller. An on-board low-dropout (LDO) linear regulator is also included to provide a +3.3V rail voltage and up to a 0.2A load current.
The MAX1785 evaluation system (EV system) includes the MAX1785 EV kit and the MINIQUSB command module. The MINIQUSB provides both an SPI™ and SMBus interface to a PC. The supplied command module allows the kit to be evaluated with Maxim's Multipurpose SMBus Software (MSS), pre-built with the MAX1785 user-interface framework. The required MAX1785 framework and MSS can be downloaded from the Maxim website (
