특징
- BATT Boost Click is a compact add-on board that expands a coin battery cell's lifetime and current capability, like the CR2032 and lithium thionyl batteries. This board features the NBM5100A, a coin-cell battery life booster with adaptive power optimization from Nexperia. It is a battery energy management device designed to maximize usable capacity from non-rechargeable, primary batteries when used in low-voltage, low-power applications requiring burst current loads. The devices overcome voltage drop and battery life limitations associated with extracting high pulse currents. This Click board™ makes the perfect solution for the development of battery-powered IoT, industrial applications, consumer and wearable devices, and more.

HOW DOES IT WORK?
BATT Boost Click is based on the NBM5100A, a coin-cell battery life booster with adaptive power optimization from Nexperia. It contains an intelligent learning algorithm and two stages of high-efficiency DC-DC conversion. The first stage, DC-DC conversion, transfers energy from the lithium battery to a capacitive storage element at a low constant current. When charged, a second DC-DC conversion cycle utilizes this stored energy to supply a regulated voltage with high pulse load current capability on the VDH output terminal. The battery is never directly subjected to large load pulse currents, resulting in a longer, more predictable battery lifetime.

The NBM5100A has a programmable constant battery load current of 2mA up to 16mA. It also features an ultra-low standby current, integrated fuel gauge, high peak power efficiency, low pulse output current, protection against battery voltage dips, and more. The capacitor balancing IO of the NBM1500A is connected to two supercapacitors and is intended for applications utilizing series-connected supercapacitors requiring voltage balancing. The input supply source of the NBM5100A can be selected from the 3.3V rail of the mikroBUS™ socket or the coin battery itself. The selection can be made over the VBT SEL jumper.
BATT Boost Click uses a standard 2-wire I2C interface to communicate with the host MCU, supporting a clock frequency of up to 1MHz. The I2C address can be selected over the ADDR SEL jumper. The auto mode utilizes the start pin (ON) for one cycle. There are two ways to define the end of the active state in auto mode: short pulse on the ON pin and long pulse on the ON pin. The NBM1500A will interrupt the host MCU when it is ready over the RDY pin.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.
