Battery powered devices require reliable, efficient, and cost effective charging solutions.LTC4095EDC#TRMPBF is a highly advanced PMIC - Battery Chargers, ideal for consumer handhelds, portable electronic equipment and intelligent systems, such as Wearables, Bluetooth Low Energy (BLE) and Internet of Things (IoT) devices. It is a compact, low-profile and thermally efficient IC that offers an integrated switching power supply and battery charger (PSU) for Li-Ion and Li-Pol chemistries. The IC is capable of charging batteries from a wide range of input sources including USB, Li-Ion cells and AC adapter.

LTC4095EDC#TRMPBF is an AC adapter and battery charge controller. Its 4.2 mA internal current regulator can satisfy the charging needs of most cell chemistries and ensures that the device is charged adequately and in a safe manner. It also utilizes two independent voltage regulators to provide regulation at two different levels. The LDO regulator can be adjusted progressively and supports applications in which the set point is set according to cell chemistry. The other adjustable regulator can be used to protect the device from over-charging and over-discharging.

The IC provides two high-side unregulated currents to the battery. The main current has a polarity controlled by the EN pin and is used to charge the battery at different levels by varying the intensity of the current in response to changing conditions. The secondary current is used to trickle charge the battery. Both the main and secondary current can be used independently or together. Additionally, the IC also includes a low-side current limiting switch for current sensing.

The IC employs an intelligent control logic to balance the input current source against the device power requirements. This logic automatically determines the charge rate and current profile and enables the device to optimize power delivery. It also conserves energy by entering into a low-power sleep mode when the battery is fully charged. Additionally, the IC provides over-voltage protection, over-temperature monitoring, protection against short circuits, over-current protection during charging, and charge termination.

The LTC4095EDC#TRMPBF is also designed to provide USB-compliant capabilities to mobile devices requiring data transfers and charging. It supports USB Type-C protocol and supports two USB charging methods-dedicated charging ports (DCP) and dedicated charging ports with suspend support (DCP/Suspend). The IC utilizes a dedicated charging ports architecture that allows it to provide power from both sides of the USB cable as well as from a single-ended source. It supports data transfer speeds up to 2.5 Mbps and provides power delivery capability up to 5V/2A for USB PD applications. It also provides over-current protection and over-voltage protection at the port.

In summary, the LTC4095EDC#TRMPBF is a highly advanced PMIC-Battery Chargers designed to provide cost-effective, efficient, and reliable solutions for powering Li-Ion/Pol batteries. It employs advanced control logic to optimize power delivery and conserves energy by entering low-power sleep mode when the battery is fully charged. It also supports data transfer and provides USB-compliant capabilities, over-current protection and over-voltage protection. This makes it an ideal solution for portable electronic equipment and intelligent systems requiring reliable, efficient charging solutions.
