Hardware Overview

How does it work?

BATT-MAN 2 Click is based on the MAX77654, a highly-integrated battery charging and power management solution for low-power applications from Analog Devices. It features a single-inductor, multiple-output (SIMO) buck-boost regulator efficiently that provides three independently programmable power rails available on onboard terminals labeled VSB0, VSB1, and VSB2. Also, it has one 100mA LDO output, labeled as VLDO, with ripple rejection for audio and other noise-sensitive applications. This LDO output can also be configured as a load switch to manage power consumption by disconnecting external blocks when not required. The LDO output can be activated/deactivated by populating the JP2 onboard jumper. The MAX77654 also has an integrated highly-configurable linear charger that supports a wide range of Li+ battery capacities with a wide range of charge current and charger termination voltage options, featuring battery temperature monitoring for additional safety (JEITA). The charger feature is OFF when the CHG

supply is invalid (supply range from 4.1V up to 7.25V), disabled, or with a fresh battery. In addition to all the output terminals on this board, another one is marked with VSYS, the system power output terminal. In addition to providing power to the system resources and the device's control logic, VSYS is also designed for external use. BATT-MAN 2 Click communicates with MCU using the standard I2C 2-Wire interface for configuring and checking the device's status. Since the sensor for operation requires a 1.8V logic voltage level to work correctly, a small regulating LDO is used, the ADP160 from Analog Devices, providing a 1.8V out of mikroBUS™ rails. That's why the voltage-level translator is also featured. The I2C interface bus lines are routed to the dual bidirectional voltage-level translator, allowing this Click board™ to work properly with 3.3V and 5V MCUs. An onboard switch labeled as ENABLE primarily generates a wake-up signal for the PMIC that turns ON the regulators by setting the switch to an appropriate position marked as 1 or 0. In addition, this Click

board™ also has some additional features, such as a Reset routed to the RST pin on the mikroBUS™ socket used to hold the processor in a Reset state when the device is powered down. It also uses an interrupt pin, the INT pin of the mikroBUS™ socket, to signal an essential change in device status, while the three additional LED indicators, red, yellow, and blue LEDs labeled as LED2, LED3, and LED4, can be used for optional user-configurable visual indication. Besides, this device includes an analog multiplexer (AMX), routed to the AN pin on the mikroBUS™ socket, that switches several internal voltage and current signals to an external node for monitoring with an external ADC. This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.

Features overview

Development board

PIC32MZ Clicker is a compact starter development board that brings the flexibility of add-on Click boards™ to your favorite microcontroller, making it a perfect starter kit for implementing your ideas. It comes with an onboard 32-bit PIC32MZ microcontroller with FPU from Microchip, a USB connector, LED indicators, buttons, a mikroProg connector, and a header for interfacing with external electronics. Thanks to its compact design with clear and easy-recognizable silkscreen markings, it provides a fluid and immersive working experience, allowing access anywhere and under

any circumstances. Each part of the PIC32MZ Clicker development kit contains the components necessary for the most efficient operation of the same board. In addition to the possibility of choosing the PIC32MZ Clicker programming method, using USB HID mikroBootloader, or through an external mikroProg connector for PIC, dsPIC, or PIC32 programmer, the Clicker board also includes a clean and regulated power supply module for the development kit. The USB Micro-B connection can provide up to 500mA of current, which is more than enough to operate all onboard

and additional modules. All communication methods that mikroBUS™ itself supports are on this board, including the well-established mikroBUS™ socket, reset button, and several buttons and LED indicators. PIC32MZ Clicker is an integral part of the Mikroe ecosystem, allowing you to create a new application in minutes. Natively supported by Mikroe software tools, it covers many aspects of prototyping thanks to a considerable number of different Click boards™ (over a thousand boards), the number of which is growing every day.

Application Output via Debug Mode

1. Once the code example is loaded, pressing the "DEBUG" button initiates the build process, programs it on the created setup, and enters Debug mode.

2. After the programming is completed, a header with buttons for various actions within the IDE becomes visible. Clicking the green "PLAY" button starts reading the results achieved with the Click board™. The achieved results are displayed in the Application Output tab.

 * @file main.c
 * @brief BATTMAN2 Click example
 *
 * # Description
 * This library contains API for BATT-MAN 2 Click driver.
 * The library initializes and defines the I2C bus drivers 
 * to write and read data from registers. 
 * The library also includes a function for configuring appropriate charge current, 
 * charge voltage, prequalification voltage, 
 * Buck, Buck-Boost and Linear regulator configuration, etc.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of the I2C module, log UART, and additional pins. 
 * After the driver inits and executes a default configuration, 
 * the app disables charging, sets charger configuration, 
 * enables charging, displays charger configuration, 
 * or sets Buck-Boost configuration.
 *
 * ## Application Task
 * This is an example that shows the use of a BATT-MAN 2 Click board™.
 * The choice of example profile tasks depends on uncommented code.
 * Examples profile: CHARGER and BUCK-BOOST.
 * In the CHARGER profile, while on the BATT-MAN 2 click board™ the 
 * blue LED is the battery charging indicator, 
 * while the red LED indicates the cessation of battery charging. 
 * The yellow LED is an indicator of the BUCK-BOOST profile.
 * Results are being sent to the USART terminal where the user can track their changes. 
 * 
 * ## Additional Function
 * - static void display_charger_status ( void )
 * - static void display_sbb_status ( void )
