LTC4075HVXEDD#PBF

The LTC4075HVXEDD#PBF is a type of PMIC (Power Management Integrated Circuit) battery charger, specifically designed to recharge mobile device batteries. It features a buck and boost topology, allowing it to charge at either a high or low voltage level. The design is also highly configurable, enabling it to be used with various battery chemistries and charging schemes. The device has a low profile, making it ideal for use in space-constrained applications such as tablets and handhelds.

The LTC4075HVXEDD#PBF utilizes a constant-current/constant-voltage (CC/CV) charge algorithm for fast and safe charging of Li-ion and Li-polymer batteries. The device has two charging channels, allowing it to charge two batteries in parallel with a total current limit of 10A. The onboard boost voltage control allows for adjustable charging voltage from 4.2V to 6V. The integrated charge termination feature safely stops the charge in the case of an over-voltage or an over-temperature condition.

The device features an integrated Power Path Management (PPM) function, providing uninterrupted power supply to the system when a main adapter is present. The integrated boost regulator can also be used to provide a regulated voltage to the battery pack during power cycling. The LTC4075HVXEDD#PBF is equipped with low dropout (LDO) linear regulators, providing feedback and load current on the charger. The device also contains a low-side power switch, which provides protection from over-current and short-circuit failures.

The LTC4075HVXEDD#PBF is designed for use in portable applications such as tablets, notebooks, and cell phones. It is also ideal for use in consumer product applications such as smart watches, MP3 players, digital cameras, and power tools. Moreover, the device is designed to be used in automotive applications, such as electric vehicle (EV) batteries and battery packs.

The LTC4075HVXEDD#PBF is an efficient and reliable battery charger, offering rapid charging and protection from over-current and over-voltage conditions. It is also highly configurable and can be used in a variety of applications, from consumer products to automotive systems.
