La carte Click Board™ BATT-MAN 3 est une carte complémentaire compacte représentant une solution avancée de gestion de batterie. Cette carte comprend l'ADP5350, un circuit intégré de gestion de l'alimentation avec LED de suralimentation inductive et trois régulateurs LDO d'Analog Devices. Cette carte programmable I2C prend en charge l'USB optimisé pour l'entrée de tension USB. Elle combine un régulateur abaisseur hautes performances pour la charge d'une seule batterie Li-Ion/Li-Ion polymère, une jauge de carburant, un régulateur de suralimentation hautement programmable pour l'éclairage du rétroéclairage LED et trois régulateurs LDO 150 mA.
Le BATT-MAN 3 Click Board™ convient aux appareils alimentés par batterie Li-Ion rechargeable et Li-Ion Polymère, aux appareils portables clients et d'instrumentation, et bien d'autres.
How Does The BATT-MAN 3 Click Board™ Work?
The BATT-MAN 3 Click Board™ as its foundation uses the ADP5350, an advanced battery management PMIC with inductive boost LED, and three LDO regulators from Analog Devices. It combines one high-performance buck regulator for single Li-ion/Li-ion polymer battery charging (also available on left side header labeled as BUCK), a fuel gauge, a highly programmable boost regulator for LED backlight illumination, one ultralow quiescent current low dropout (LDO) regulator, and two general-purpose LDO regulators. Besides, it supports a USB connection optimized for USB 5V input.
The ADP5350 operates in trickle charge mode and constant current (CC)/constant voltage (CV) fast charge mode. It also features an internal field-effect transistor (FET) that permits battery isolation on the system power side. The ADP5350 fuel gauge is a low current consuming solution optimal for rechargeable Li-Ion battery-powered devices. Its boost regulator operates at a 1.5MHz switching frequency and can be employed as a constant voltage regulator or supplemental constant current regulator for multiple LED backlight drivers available on the VOUT4 terminal.
This LED driver can support a wide range of LED backlight configurations, either multiple LEDs in parallel or series connected on the upper-right onboard header. This Click board™ also has a feedback-sensing for the boost regulator, which can be selected for standalone mode or LED operation mode by positioning the SMD jumpers labeled as MODE SEL to an appropriate position marked as STAL and LED. An additional option has been added for the users to activate or deactivate the Boost and LED part of the board by populating or removing two jumpers, R11 and R9.
The BATT-MAN 3 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings with a maximum frequency of 400kHz. Also, it uses several GPIO pins, one of which is an interrupt pin, the INT pin of the mikroBUS™ socket, used as a 'fault' indicator which immediately notifies the host when a fault occurs. The ADP5350 low dropout (LDO) regulators, available on top side terminals labeled from VOUT1 to VOUT3, are optimized to operate at low shutdown current and quiescent current to extend battery life. The device also acts as a load switch that can be fully turned OFF or ON. The I2C interface enables the programmability of all parameters, including status bit readback for operation monitoring and safety control.
The BATT-MAN 3 Click Board™ uses two LED indicators, labeled as PGOOD and BATT OK, used as power good and charging status indicator alongside the connector on the upper-left side of the board, reserved for a Li-ion/Li-ion polymer battery. PGOOD indicates a good input source, while BATT OK shows the real-time status of the battery voltage. Also, it features battery pack temperature sensing via an internal or external thermistor connected to the onboard header labeled as NTC. This sensing precludes charging when the battery pack temperature is outside the specified range. The selection of a thermistor can be made by positioning the SMD jumpers labeled as TMP SEL to an appropriate position marked as EXT and INT.
The BATT-MAN 3 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. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.
