BQ24230RGTT

Battery Chargers Overview

The BQ24230RGTT is a USB-powered lithium-ion battery charger from Texas Instruments, designed for low-power applications. It features an integrated power path management system and operates within a supply voltage range of 4.3 V to 6.5 V. The device delivers a maximum output current of 500 mA with a fixed charge voltage of 4.2 V. Housed in a compact 16-pin VQFN package, it supports surface-mount installation and functions across a temperature range up to 85 °C.

Battery Chargers Feature Summary

• Integrates dynamic power path management to prioritize system load over battery charging when input current is limited.
• Includes a 6.6 V overvoltage protection (OVP) threshold to safeguard against excessive input voltage conditions.
• Supports USB-friendly operation by managing input current limits compatible with standard USB host ports.

Battery Chargers Applications

• Portable electronic devices requiring single-cell lithium-ion battery charging
• Low-power consumer electronics powered via USB interfaces
• Applications necessitating integrated power path management for system efficiency

Battery Chargers Procurement Notes

Verify the specific suffix RGTT corresponds to the cut tape or reel packaging variant required for your assembly process. Confirm that the 16-VQFN footprint matches your PCB layout guidelines. Ensure the 6.5 V maximum operating voltage aligns with your upstream power source specifications to prevent OVP triggering during normal operation.

Battery Chargers Selection Notes

Select this component for designs requiring a compact solution for single-cell lithium-ion batteries with moderate charging currents. It is suitable where space constraints favor the VQFN-16 package. Consider alternative models if higher charging currents or wider input voltage ranges are necessary for the target application.

Battery Chargers Part Context

This part belongs to the bqTINY family of battery chargers, emphasizing small form factors and integration. It complements other Texas Instruments PMICs by providing dedicated charge management for portable devices. The RGTT suffix indicates a specific tape-and-reel or cut-tape configuration within the broader BQ24230 series lineup.

Battery Chargers Replacement Considerations

BQ24230RGTR serves as a direct pin-compatible alternative differing primarily in packaging format. Evaluate BQ24232 variants if extended input voltage support beyond 6.5 V is required, noting potential differences in feature sets and thermal performance.
