STBC02AJR

Overview

The STBC02AJR is a highly integrated power management IC from STMicroelectronics, designed for single-cell lithium-ion and lithium-polymer batteries. It embeds a linear battery charger with a maximum charge current of 450 mA, an LDO regulator, load switches, and a reset generator. The device supports a supply voltage up to 5.4 V and operates within a temperature range of -40°C to 85°C. It utilizes a CC/CV charging algorithm with programmable fast and pre-charge currents. The component is housed in a 30-UFBGA flip-chip package measuring 2.59x2.25 mm.

Feature Summary

Integrates a linear battery charger with automatic power path management for seamless system operation during charging.

Applications

Single-cell Li-Ion/Li-Po battery charging systems
Portable electronic devices requiring compact power management

Procurement Notes

Verify the specific suffix 'JR' against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with the 30-UFBGA flip-chip package dimensions and soldering profiles. Cross-reference with the latest product change notices to confirm assembly and sourcing details before finalizing procurement.

Selection Notes

Select this component when a highly integrated solution combining battery charging, LDO regulation, and load switching is required for single-cell applications. Consider the 450 mA maximum charge current and the 30-pin flip-chip package constraints. Verify that the programmable current settings and protection features align with the target battery chemistry and safety standards.

Part Context

The STBC02AJR belongs to the STBC02 family of power management ICs. This family is characterized by high integration, embedding multiple functions such as charging, regulation, and protection into a small footprint. The AJR variant shares the core architecture with other members like the STBC02BJR, differing primarily in specific ordering or packaging suffixes defined by the manufacturer.
