Overview
The STBC15QTR is a linear battery charger from the STBC15 series, designed for ultra-low current consumption applications. It supports Lithium-ion batteries with an output voltage of 4.2 V and an output current of 40 mA. The device operates within a supply voltage range up to 6.5 V and features a quiescent current of 580 nA. It is housed in a FlipChip-12 package (UFQFN12) suitable for surface mount technology. The component functions across a temperature range of -40°C to +85°C.
Feature Summary
- Ultra-low current consumption design for extended battery life
- Linear charging architecture optimized for single-cell lithium-ion batteries
- Compact FlipChip-12 packaging for space-constrained designs
Applications
- Portable consumer electronics requiring low standby power
- Wearable devices with limited battery capacity
- IoT sensors utilizing single-cell lithium-ion power sources
Procurement Notes
Verify the specific suffix 'QTR' against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the target PCB footprint for the FlipChip-12 configuration. Cross-reference the part number with the latest datasheet revision to validate electrical parameters and operating temperature ranges before integration.
Selection Notes
Select this component when ultra-low quiescent current is critical for system efficiency. The 40 mA output current limits suitability for high-capacity battery charging scenarios. Evaluate the thermal performance within the UFQFN12 package constraints. Confirm that the input voltage does not exceed the 6.5 V maximum rating during operation.
Part Context
The STBC15QTR belongs to the STBC15 family of battery management ICs from STMicroelectronics. This series focuses on energy-efficient charging solutions for portable devices. The QTR suffix typically denotes the reel packaging format, distinguishing it from other variants like the STBC15JTR which may share similar electrical characteristics but differ in packaging or ordering units.
Replacement Considerations
The STBC15JTR is a documented variant within the same series, offering identical electrical specifications including 4.2 V output and 40 mA current. Verify if the packaging difference between QTR and JTR impacts the assembly process. No other direct substitutes are confirmed in the provided data.
