Evaluation Kit for the MAX17085B

Active: In Production.

The MAX17085B evaluation kit (EV kit) is a complete and fully assembled and tested PCB that features the MAX17085B IC, a highly integrated, multichemistry battery-charger controller with dual step-down converters and dual LDOs. The EV kit is capable of supplying power to a system load while simultaneously charging multichemistry battery packs. During operation, the EV kit circuit automatically selects the ADAPTER input or the battery as the main power source for supplying power to the system load and step-down converters. Whenever the EV kit circuit current limit is exceeded, the battery-charge current is reduced automatically, giving priority to the system load and converters.

The EV kit's input source-current limit, battery-charge voltage, maximum battery-charge current threshold, and output current limit on the step-down converters are configurable. These thresholds are adjusted by using on-board circuitry, or by connecting analog signals to the EV kit. Digital output signals indicate the presence of a valid ADAPTER and valid step-down converter voltages. An analog output signal indicates the total current drawn from either the adapter or the battery.
