Power management integrated circuits (PMICs) play a critical role in various medium to high-power applications. PMICs feature fixed, adjustable, dual and multi-output configurations with a host of integrated peripherals to meet system needs. By integrating multiple power supplies, PMICs provide more efficient control, monitoring, and protection functions. One of the popular PMICs in Power Management - Battery Chargers category is BQ24030RHLR.

The BQ24030RHLR is a highly integrated stand-alone Li-ion/ Li-polymer battery charger with power path management. Its integrated input sensing, battery monitoring, and charging control allows it to fit many applications like Wearables, Battery Packs, Wireless Charging, and Portable Electronics. This compact, thermally and ESD-protected package ensures reliable operation in harsh environments.

The BQ24030RHLR built-in switching Power-Path (PP) and Power-Supply-in-Package (PSIP) regulator to manage the power-path and provide power to the system directly from the battery or from the adapter. The PP managed input FET is designed to minimize during the battery charging, improving efficiency and reducing power dissipated. It provides high-power/high-efficiency output current, reducing the battery charging time, prolonging battery life and optimizing Portable device performance.

The BQ24030RHLR integrates all primary protection functions like input-voltage limit over-voltage protection, weak-battery detection, and force-charge termination. The PP input and output charge-current are programmable, on-board sense resistor, and a power source switch control with user-selectable charging profiles. The PP input current is 1A and the output current is 1.25A.

The BQ24030RHLR utilizes charge detection and state-of-charge (SOC) monitoring. This feature detects whether an input power source is present, and whether the battery is over-charged or full-charged. The SOC monitoring also enables recharge auto-restart of the remaining charging cycles, if the battery is discharged while connected to the PT charge circuit. The auto-detect safety timer allows the charger always to be in the safety condition while monitoring the process, and ensures that the user’s charge needs are always met.

In summary, the BQ24030RHLR is an advanced and reliable two-cell Li-Ion battery charger and power path management solution for Wearables, Battery Packs, Wireless Charging, and Portable Electronics applications. Features include a 1A switchable Power-Path and Power-Supply-in-Package regulator, 1.25A output current, safety timer and integrated protection functions, charge detection and state-of-charge monitoring, and programmable on-board sense resistor. The BQ24030RHLR helps the user to optimize their system design, reduce board area, and minimize the number of components.
