I. ADI Battery Chargers: The Core of Efficient and Safe Battery Energy Storage

The ADI battery charger series offers high integration, wide voltage compatibility, intelligent charging control and multiple safety protections as its core advantages. It eliminates the cumbersome design of traditional discrete charging solutions by integrating functions such as power switching, power source selection, temperature protection and adaptive current and voltage regulation. Supporting both linear and buck-boost switching charging modes, it can accommodate the diverse requirements of both low-power, compact devices and high-power fast-charging equipment, whilst remaining compatible with a wide range of battery chemistries.

1. Core Technologies and Product Advantages

Equipped with ADI’s proprietary AccuCharge™ precision charging technology, these solutions dynamically modulate the charging MOSFETs to precisely regulate charging voltage, current and power device temperature. This enables fine-grained control across all stages of constant-current, constant-voltage and trickle charging, effectively preventing issues such as overcharging, undercharging and battery overheating, whilst significantly extending battery cycle life. It also integrates Smart Power Selector™ technology, which automatically switches between power supply and charging modes, prioritising power delivery to the device’s load whilst utilising any remaining power for battery charging, thereby ensuring efficient allocation of the input power.

The entire range of chargers features ultra-low quiescent power consumption, with standby power consumption as low as the microampere level, effectively reducing battery drain whilst the device is in sleep mode; they support a wide input voltage range, accommodating various power sources such as adapters, USB and solar panels, and incorporate built-in overvoltage, overcurrent, overtemperature and reverse-connection protection, meeting safety standards for high-reliability applications such as industrial and medical settings.
