Evaluating the MAX17616

See projects/max17616 (doxygen) for the Doxygen documentation.

The MAX17616EVKIT# evaluation circuit features the MAX17616 eFuse setup for 5V to 28V operation with a 7A auto-retry current limit. A 3.3V buck regulator provides a voltage for pull-ups and logic to run indicator LEDs on the board.

While the MAX17616AEVKIT# evaluation kit (EV kit) features the MAX17616A eFuse setup for 5V to 28V operation with a 2A auto-retry current limit. A 3.3V buck regulator provides a voltage for pull-ups and logic to run indicator LEDs on the board.

Both boards include an additional external N-channel FET for reverse conduction protection.

Applications

No-OS Build Setup

Please see: https://wiki.analog.com/resources/no-os/build

No-OS Supported Examples

The initialization data used in the examples is taken out from: Project Common Data Path

The macros used in Common Data are defined in platform specific files found in: Project Platform Configuration Path

Basic example

This is a simple example that initializes the MAX17616, and performs telemetry readings of the voltage, current and temperature. Status bytes/words are also monitored in the example.

In order to build the basic example make sure you have the following configuration in the Makefile Basic Example Makefile

EXAMPLE ?= basic

IIO example

This project is actually a IIOD demo for MAX32655FTHR evaluation board. The project launches a IIOD server on the board so that the user may connect to it via an IIO client.

If you are not familiar with ADI IIO Application, please take a look at: IIO No-OS

If you are not familiar with ADI IIO-Oscilloscope Client, please take a look at: IIO Oscilloscope

The No-OS IIO Application together with the No-OS IIO MAX17616 driver take care of all the back-end logic needed to setup the IIO server.

This example initializes the IIO device and calls the IIO app as shown in: IIO Example

In order to build the IIO project make sure you have the following configuration in the IIO Example Makefile
