BQ24705RGER

Battery Chargers Overview

The BQ24705RGER is a host-controlled multi-chemistry battery charger manufactured by Texas Instruments. It supports lead-acid, Li-ion, NiCd, and NiMH batteries with an input voltage range of 8V to 18V and a maximum charge current of 8000mA. The device features low input power detection and adjustable thresholds. It is housed in a 24-pin HVQCCN (VQFN) package with an exposed pad, measuring 4mm in length. The component operates within a temperature range of -40°C to 125°C and complies with RoHS standards.

Battery Chargers Feature Summary

• Host-controlled architecture for system integration
• Supports multiple battery chemistries including lead-acid and lithium-ion
• Integrated low input power detection capability

Battery Chargers Applications

• Portable computing devices
• Industrial equipment requiring multi-chemistry support
• Battery management systems with host control interfaces

Battery Chargers Procurement Notes

Verify the specific suffix 'RGE' corresponds to the 24-pin VQFN tape-and-reel packaging configuration. Confirm that the required operating temperature range extends to 125°C, as this exceeds standard commercial limits. Ensure the host controller interface compatibility matches the design requirements before procurement.

Battery Chargers Selection Notes

Select this component when a single-chip solution for diverse battery types is required alongside host-side monitoring. The high current capacity suits applications demanding rapid charging profiles. Verify that the PCB layout accommodates the exposed thermal pad for adequate heat dissipation under full load conditions.

Battery Chargers Part Context

This part belongs to the BQ24705 family of battery chargers. It shares functional similarities with other host-controlled chargers but is distinct in its multi-chemistry support and specific pinout configuration. The RGE suffix denotes the specific package type and reel quantity, differentiating it from other variants like the RGTT or RGET.

Battery Chargers Replacement Considerations

Direct replacements may include other BQ24705 variants with compatible pinouts. Verify electrical parameters such as input voltage range and max current against the original design specifications to ensure functional equivalence.
