The LT3485EDD-3#PBF is a specialized power management integrated circuit (PMIC) designed for mobile device applications where power efficiency, space and cost are important. Its design combines a voltage regulator and a battery charger in one integrated package. The device is capable of delivering up to 625mA of output current, and has a wide input voltage range of 2.9 to 17V. It is well suited for use in smartphones, tablets, and other mobile device applications.

The LT3485EDD-3#PBF consists of three main functional areas: a voltage regulator, a battery charger, and an enable signal generator. The voltage regulator is a low-dropout (LDO) regulator. It operates in a very low-noise, low-ripple, low power mode, and is capable of providing a steady output voltage, which can be adjusted from 1.8 to 8V. The battery charger is designed to automatically detect the battery type, charge safely, and protect the battery from overcharging. It offers several charging algorithm options and can support Li-Ion, Li-Po, NiMH, NiCd and LiFePO4 batteries.

The enable signal generator is used to control the sequencing, power-up, and power-down of embedded circuitry. It is capable of generating up to 6 logic signals. The logic output signals are configured via an internal register, allowing multiple logic signals to be set up with various active high and active low conditions. The enable signal generator allows users to pair the LT3485EDD-3#PBF with their embedded system, to control power sequencing, monitor battery voltage, and perform board-level power-management operations.

The LT3485EDD-3#PBF is an ideal power management solution for many embedded systems. Its integrated design enables space and cost savings. It offers high power efficiency, up to 95%, and supports various battery types, while providing accurate power regulation and enable signal control. Its low-noise, low-ripple operation makes it suitable for many low-power applications, including portable devices, medical devices, automotive infotainment systems, and industrial sensors.
