BQ24650RVAR

Battery Chargers Overview

The BQ24650RVAR is a high-efficiency synchronous switching-mode battery charger controller from Texas Instruments, designed for versatile energy harvesting applications. It supports multiple battery chemistries including Lead Acid, Lithium-ion, Lithium Polymer, and LiFePO4. The device operates with an input supply voltage range of 5 V to 28 V and delivers a programmable output current up to 10 A. It features an adjustable output voltage and functions within a temperature range of -40°C to +85°C. Packaged in a 16-pin VQFN (3.5x3.5 mm) surface-mount case, it integrates MPPT capabilities and protection features.

Battery Chargers Feature Summary

• Supports synchronous buck converter topology for high-efficiency charging across various battery types.
• Integrates maximum power point tracking (MPPT) algorithms optimized for solar photovoltaic energy applications.
• Includes comprehensive protection mechanisms such as over-temperature, over-voltage, and current fault protection.

Battery Chargers Applications

• Solar photovoltaic energy systems for isolated generating setups
• Smart battery chargers utilizing synchronous buck converter topologies
• Energy harvesting applications requiring MPPT optimization

Battery Chargers Procurement Notes

Verify the suffix 'RVAR' corresponds to the tape-and-reel packaging configuration when ordering. Confirm that the specific battery chemistry selected aligns with the controller's supported types, including Lead Acid, Li-ion, LiPo, and LiFePO4. Ensure the design accommodates the 5 V to 28 V input range and 10 A current capability. Check humidity sensitivity requirements during storage and handling procedures.

Battery Chargers Selection Notes

Select this component for designs requiring flexible input voltages up to 28 V and support for diverse battery chemistries. It is suitable for applications needing integrated MPPT functionality without external microcontrollers. Consider the 16-VQFN package for space-constrained PCB layouts. Validate thermal performance given the operating temperature range and potential conduction losses in high-current scenarios.

Battery Chargers Part Context

The BQ24650RVAR belongs to the BQ24650 series of charge management ICs from Texas Instruments. It is categorized under PMIC - Power Management ICs and specifically Battery Management. The 'RVAR' suffix indicates the reel packaging variant, distinct from the cut-tape 'RVAT' version. It serves as a controller for synchronous switching-mode chargers rather than a complete standalone solution.
