BQ24800RUYR

Battery Chargers Overview

The BQ24800RUYR is a synchronous buck battery charge controller from Texas Instruments, designed for 1 to 4-cell lithium-ion or polymer packs. It operates with input voltages from 4.5V to 24V and supports output currents up to 8A at 19.2V. The device integrates hybrid power boost and battery-only boost modes for system power management. It features SMBus communication, programmable current limits, and high-accuracy monitoring. Packaged in a 28-WQFN (4x4) surface-mount case, it functions within a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Hybrid power boost mode enables simultaneous powering from adapter and battery with ultra-fast transient response
• Battery only boost mode extends runtime by regulating system voltage when adapter is absent
• High accuracy power and current monitoring supports CPU throttling and system protection
• Automatic NMOS power source selection ensures seamless transition between AC and battery sources

Battery Chargers Applications

• Laptops and ultrabooks
• Detachable computers and tablets
• Industrial and medical equipment
• Portable devices with backup batteries

Battery Chargers Procurement Notes

Verify the complete part number including suffix RUYR to confirm the specific tape and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering quantity matches the manufacturer's standard reel size to avoid cut-tape premiums. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Battery Chargers Selection Notes

Select this component for applications requiring compact designs with minimal external components. It is suitable where space constraints limit the use of discrete power path solutions. The integrated boost modes make it ideal for systems needing uninterrupted operation during adapter removal. Consider the thermal performance of the WQFN package for high-current charging scenarios.
