STBC02BJR

Overview

The STBC02BJR is a highly integrated power management IC embedding a linear battery charger, a 150 mA LDO, two SPDT load switches, a smart reset/watchdog block, and a protection circuit module. It utilizes a CC/CV algorithm for single-cell Li-Ion batteries, with fast charge current up to 450 mA and pre-charge current from 1 mA to 450 mA. The floating voltage is programmable up to 4.45 V. Available in Flip Chip 30 package.

Feature Summary

• Integrates linear battery charger, 150 mA LDO, dual SPDT load switches, and smart reset/watchdog
• Implements CC/CV charging algorithm with independently programmable fast and pre-charge currents
• Includes embedded protection circuit module for overcharge, over-discharge, and overcurrent safety
• Features shipping mode with less than 10 nA battery leakage to maximize shelf life

Applications

• Single-cell Li-Ion battery charging in portable consumer electronics
• Power management units requiring integrated load switching and reset generation
• Devices requiring low standby current during storage or shutdown modes

Procurement Notes

Verify the complete part number including suffix against official STMicroelectronics documentation to ensure correct package type and temperature range specifications. Confirm that the Flip Chip 30 package variant matches the design requirements. Cross-reference the ordering code with the latest datasheet revision to avoid discrepancies in pinout or electrical characteristics. Ensure compatibility with the intended battery chemistry and system voltage levels before procurement.

Selection Notes

Select this component when a compact solution combining battery charging, power regulation, and load switching is required. The integrated nature reduces external component count compared to discrete solutions. Consider the 150 mA LDO output capability and the specific load switch configurations for system architecture. Evaluate the programmability of charge parameters against the target battery specifications and safety requirements.

Part Context

The STBC02 belongs to STMicroelectronics' portfolio of highly integrated power management devices designed for mobile applications. It addresses the need for space-constrained designs by consolidating multiple power functions into a single small footprint. The device complements other ST power solutions by providing specialized battery management capabilities alongside standard regulation features.

Replacement Considerations

Consult official STMicroelectronics substitution guides for verified alternative part numbers. Direct replacements must maintain identical functionality, pinout compatibility, and electrical specifications. Verify any substitute component's compliance with the original design constraints regarding package dimensions and thermal performance.
