BQ24650RVAT 概要
A battery charge controller is a power-management semiconductor that regulates energy transferred from a source such as a solar panel into a rechargeable battery. In the broader hierarchy, a battery charge controller belongs to battery-management and power-management ICs. This device specifically uses a synchronous buck topology, supporting efficient conversion from solar input to battery voltage while reducing charge current when input voltage falls below the programmed operating region.
The BQ24650 integrates Maximum Power Point Tracking, commonly called MPPT, for extracting available power from a solar source. According to the Texas Instruments product page, it provides input-voltage regulation and charge-current optimization. The verified distributor listing identifies the part as a solar-charging MPPT PMIC in a 16-pin VQFN package, while the manufacturer describes the BQ24650 as a standalone 1- to 6-cell buck battery charge controller for solar input.
Typical electrical features include support for lead-acid, LiFePO4, lithium-ion, and lithium-polymer battery families, as identified in the verified component listing. The controller is intended for solar-powered battery systems where source availability and input-voltage variation can change the available charging current. Designers should validate the exact cell count, battery chemistry, charge voltage, charge current, switching components, and thermal conditions against the manufacturer datasheet before releasing a production design.
The 16-pin VQFN (RVA) package is a surface-mount package and is represented by the vqfn-16 package diagram key. The verified Texas Instruments part-details listing specifies 16 pins and an operating temperature of -40 °C to 85 °C. The exact electrical limits, pin names, compensation requirements, and recommended external components are available in the linked manufacturer datasheet.
A key design consideration is power-stage sizing: the controller charges at up to 10 A according to the verified component data, so the inductor, MOSFETs, input capacitors, output capacitors, PCB copper, and thermal path must be selected for the actual battery voltage and solar-input range. Do not assume that a generic buck circuit is sufficient without checking the BQ24650 datasheet and application requirements.
This product page consolidates verified manufacturer and distributor information, package data, application context, and practical engineering considerations. It does not infer missing electrical limits, pricing, pin functions, or alternative compatibility when those values are not present in the supplied data.

主な用途
BQ24650RVAT の用途: 7 件s: Solar-Powered Battery Charger, Portable Solar-Power Battery Pack, Lead-Acid Energy Storage, LiFePO4 Battery Charging, Lithium-Ion Solar Charger, Lithium-Polymer Solar Charging, Remote Solar-Powered Instrumentation.
Solar-Powered Battery Charger
BQ24650RVAT is designed for solar battery charging because the verified data identifies integrated MPPT, a synchronous buck topology, up to 10 A charging, and a maximum input voltage of 28 V. Place the controller in the power path between the solar source and a one- to six-cell rechargeable battery, then configure the input operating point and battery charge profile with the manufacturer guidance. MPPT can improve available-energy extraction when irradiance changes, while charge-current optimization reduces current when input power is insufficient. The 10 A capability still depends on the selected inductors, MOSFETs, capacitors, PCB copper, and enclosure thermal path.
おすすめ
Portable Solar-Power Battery Pack
The BQ24650RVAT fits portable solar-power systems where a compact controller must regulate changing panel output into a rechargeable battery. Its 16-pin VQFN RVA package helps preserve board area, while the 3.5 mm by 3.5 mm format supports dense power-converter layouts. The controller’s MPPT and charge-current optimization are useful when the available solar power varies during outdoor use. For a portable pack, verify the 28 V maximum input condition, battery-cell count, charge current, standby behavior, and enclosure temperature against the complete datasheet before selecting external components.
おすすめ
Lead-Acid Energy Storage
BQ24650RVAT can be evaluated for lead-acid energy-storage applications because the verified component data explicitly lists lead-acid among the supported battery types. Its synchronous buck architecture is intended to transfer energy from the solar source into the battery while regulating the operating point and optimizing charge current. The battery’s required charge voltage, absorption behavior, temperature limits, and cell count must be matched to the controller configuration. Because those chemistry-specific thresholds are not fully present in the supplied data, engineers should use the manufacturer datasheet rather than selecting values from generic charger circuits.
おすすめ
LiFePO4 Battery Charging
The BQ24650RVAT is a candidate for LiFePO4 charging systems because LiFePO4 is explicitly included in the verified supported-battery listing. MPPT can help maintain useful solar-input behavior as available irradiance changes, while the synchronous buck stage provides the controlled charging path. The key engineering checks are battery cell count, charge-voltage limits, current capability, temperature range, and termination behavior. Since the supplied data does not provide the complete LiFePO4 profile or pin-level configuration table, the final settings must come from the official BQ24650 datasheet.
おすすめ
Lithium-Ion Solar Charger
BQ24650RVAT can support lithium-ion solar charging where the battery count and charge profile match the controller’s one- to six-cell range. The verified data lists Li-ion as a supported chemistry and identifies up to 10 A charging capability. Use the controller’s input regulation and charge-current optimization to manage changing solar conditions, but size the power stage for the actual battery voltage and current. A production design should also include protection and validation appropriate to the battery chemistry, system operating environment, and required safety margins.
おすすめ
Lithium-Polymer Solar Charging
The BQ24650RVAT is relevant to lithium-polymer solar charging because Li-pol appears in the verified supported-battery list. Its integrated MPPT and synchronous buck operation make it suitable for controlling energy from a variable solar source into a compact battery system. The controller should be configured only after confirming the battery’s voltage, current, temperature, and charge-termination requirements. The 16-pin VQFN RVA package supports compact layouts, but exposed-pad thermal management and the surrounding power components remain essential at high charge current.
おすすめ
Remote Solar-Powered Instrumentation
BQ24650RVAT can serve remote solar-powered instrumentation where energy availability changes with sunlight and battery charging must be controlled. The device’s MPPT, input-voltage regulation, and charge-current optimization functions help the charger respond to changing source conditions, while the synchronous buck topology supports an organized power-conversion path. Remote installations should be evaluated for wide temperature swings, enclosure heat, reverse-current protection, wiring transients, and battery maintenance. The verified operating-temperature range is -40 °C to 85 °C, but the complete datasheet is needed for thermal and electrical design details.

設計ノート
Design the solar input and battery power stage around the verified 28 V maximum input-voltage figure and up-to-10 A charging capability. Confirm the actual panel open-circuit voltage, battery charge voltage, inductor ripple current, MOSFET voltage rating, capacitor ripple current, and output-current margin in the manufacturer datasheet. Do not select the external power components from the controller’s nominal current rating alone.
At high charging currents, losses in the controller, MOSFETs, inductor, and PCB copper can raise junction and board temperatures. Place the VQFN exposed pad over the manufacturer-recommended copper area, provide thermal vias where allowed, and keep the power loop compact. Validate the enclosure temperature and heat spreading with a worst-case solar-input, battery-voltage, and charge-current calculation.
Use the official RVA package layout and pinout as the authority for PCB construction. Keep the high-current switching loop small, place input and output capacitors close to their intended power-stage nodes, and route sense and control signals away from switching-node transitions. Check the manufacturer’s recommended layout and component values before releasing a board spin.
A solar charger can experience changing irradiance, open-circuit panel voltage, battery aging, and temperature variation. Confirm MPPT configuration, input regulation behavior, charge-current limits, and battery-specific charge thresholds rather than assuming one universal setting. The supplied data does not include the complete pin functions or chemistry-specific thresholds, so those values must be verified in the manufacturer datasheet.
コンプライアンス情報
The supplied manufacturer and distributor snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred.
