BATT-MAN Click

How does it work?

BATT-MAN Click is based on the LTC3586, an integrated high-efficiency power manager from Analog Devices that features a versatile combination of switching regulators - boost, buck-boost, and dual buck converters - alongside an intelligent PowerPath™ controller with Bat-Track™ adaptive output control for optimized power flow and system stability. This board is a compact power management solution that combines advanced battery charging and multiple regulated power outputs on a single board. This Click board™ offers three independent regulated outputs. A low-current 3.3V LDO output supplies up to 30mA, ideal for light loads and always active by default. A high-current 3.3V output supports up to 1A, while an additional 5V output delivers up to 800mA, both suitable for more demanding applications. All outputs are conveniently accessible via onboard screw terminals, ensuring a secure and flexible connection to external devices.

BATT-MAN Click includes a full-featured LiPo battery charger with constant current/constant voltage control, automatic recharge, trickle charging for low-voltage cells, and safety features such as bad cell detection and timeout-based termination. The battery float voltage is fixed at 4.2V, matching the LiPo batteries available from the MIKROE shop. An onboard CHG status indicator provides real-time feedback on the charging process through a red LED, driven by an open-drain CHG pin that signals charging, standby, or battery fault conditions. Robust system monitoring is enhanced by the FLT pin, which detects output faults by monitoring the feedback voltages of the switching converters. In the event of a regulation failure, this bidirectional pin pulls LOW and disables all converters. It can also be used externally to shut down the regulators manually.

The device supports flexible startup and control. An onboard EN Vout switch (SW1) allows manual activation of outputs even without 5V mikroBUS™ power, as long as a LiPo battery is connected. Regulator enable lines are routed to the mikroBUS™ EN pin, allowing MCU-based control. In addition to screw terminals for power outputs, a standard 2.54mm battery connector is provided for seamless integration of a LiPo battery.

This Click board™ can be operated only with a 5V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. It also comes equipped with a library containing functions and example code that can be used as a reference for further development.

BATT-MAN Click electrical specifications

Software Support

BATT-MAN Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

BATT-MAN Click is a very versatile battery operated power manager. When powered via mikroBUS, it will charge the connected Li-Ion/Li-Po 3.7V battery, while providing the output voltage on all its outputs at the same time.

Key Functions

• battman_cfg_setup Config Object Initialization function.
• battman_init Initialization function.
• battman_set_enable Controls the operation of the Click.
• battman_get_charging_indicator Charging indicator status.

Application Init

Initializes the Click driver and logger utility and enables the Click board.

Application Task

Checks the charging indicator status, and in relation to its state it displays an appropriate message on USB UART.

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
