The BQ25015RHLT is an advanced high frequency, high efficiency, synchronous constant current/constant voltage linear charger for single cell Li-Ion and Li-Polymer batteries. The device offers up to 1.5A charging current, up to 8V input voltage, and a programmable charge inhibit input for multiple cells with independent charge control. It also has a five-pin programmable control interface (PCIF) for advanced control of charging parameters.

The BQ25015RHLT is designed for high-reliability and maximum efficiency in extreme operating environments. It operates over a wide temperature range and includes several fault protection features to ensure battery safety and reliability. The device also integrates a high-efficiency synchronous buck that reduces component count and increases the overall efficiency of the charge cycle.

The BQ25015RHLT is a member of Texas Instruments\' Battery-Charging Portfolio and is part of its next-generation, high-performance charging solutions for single-cell Li-Ion and Li-Polymer batteries. This device delivers high-efficiency, fast-charging, and steady regulation performance. It is an ideal solution for space-constrained, high-power designs.

The BQ25015RHLT operates in one of three operating modes that can be programmed with the PCIF. The three operation modes are buck-only, linear-only and constant current/constant voltage (CCC). Each mode has specific capabilities for charging different kinds of batteries. The linear-only mode is designed to provide fast charging with a constant current and over-voltage protection. The buck-only mode is designed for economical, low-voltage applications with a constant voltage regulation and over-current protection. The CCC mode is used to charge Li-Ion and Li-Polymer batteries with an optimized charging profile.

The device\'s operating parameters and features can be fine-tuned by programming the PCIF. The PCIF can be used to program the output voltage, current, and other features including timer settings, over-voltage protection, and more. The PCIF allows the user to customize the device to their specific needs.

The BQ25015RHLT is an ideal solution for advanced charging needs in space-constrained, high-power designs. It offers a compact size and a wide range of features for efficient and fast charging. The device can be used in a wide range of applications such as automotive, consumer electronics, medical, and industrial systems.
