BQ24133RGYT

Battery Chargers Overview

The BQ24133RGYT is a stand-alone Li-Ion and Li-Polymer switched-mode battery charger featuring integrated N-channel power MOSFETs. It operates with an input voltage range of 4.5 V to 17 V and supports 1- to 3-cell battery configurations at 4.2 V per cell. The device delivers a maximum charge current of 2.5 A using a 1.6-MHz synchronous buck architecture. It includes an automatic power path selector, adjustable input overvoltage protection, and thermal regulation loops for safety.

Battery Chargers Feature Summary

• Integrates 20-V switching MOSFETs and a bootstrap diode within a single package
• Provides automatic power path selection between the adapter and the battery
• Monitors battery pack temperature to enable hot/cold charge suspend and detection
• Features internal digital soft start and dynamic power management capabilities

Battery Chargers Applications

• Tablet PCs
• Netbooks and ultra-mobile computers
• Portable data capture terminals
• Medical diagnostics equipment
• Battery bay chargers

Battery Chargers Procurement Notes

Verify the specific suffix 'RGYT' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the component meets RoHS3 compliance standards as indicated in official documentation. Ensure the ordering quantity aligns with the manufacturer's standard reel specifications to avoid handling discrepancies during production integration.

Battery Chargers Selection Notes

Select this component when designing systems requiring high-efficiency charging for 1 to 3 series lithium cells. The integrated MOSFET design reduces external component count compared to non-integrated alternatives. Verify that the application environment stays within the specified -40°C to +85°C operating temperature range and that the input supply voltage does not exceed the 17 V limit.

Battery Chargers Part Context

This part belongs to the BQ24133 family of synchronous switched-mode chargers from Texas Instruments. It shares core functionality with variants like the BQ24133RGYR, differing primarily in packaging format. The device is categorized under PMIC battery chargers and utilizes a 24-pin VQFN package suitable for space-constrained portable electronics designs.

Battery Chargers Replacement Considerations

The BQ24133RGYR serves as a pin-compatible alternative with identical electrical characteristics but differs in reel packaging type.
