BQ51013C-Q1 Overview
A wireless power receiver is the secondary-side device in an inductive charging system. It receives energy from a transmitter through a receiver coil, converts the alternating coil voltage into a regulated DC output, and communicates with the transmitter. The BQ51013C-Q1 places the Qi communication protocol, rectification, regulation, and control functions between the receiver coil and the powered load, reducing the number of external ICs required for a Qi v1.3 receiver design.
The verified manufacturer material highlights a 93% peak AC-DC efficiency target in the family datasheet text, full synchronous rectification, accurate voltage and current loops, and output-voltage conditioning. These features are relevant when designing a compact receiver whose power loss can become heat inside a phone, accessory, or automotive console. The Q1 device is intended for automotive wireless-power applications, while the product-family information identifies the BQ51013C family as delivering up to 5 W.
Typical applications include 5 W wireless charging for portable devices, automotive center-console charging pads, accessory power for battery-operated products, and embedded wireless-power modules where the receiver IC must sit close to a coil and provide controlled DC output. The receiver-side architecture is important: coil coupling, alignment, thermal conditions, communication timing, output loading, and the downstream power path all affect the user experience.
For implementation, follow the manufacturer datasheet for the RHL package pinout, recommended coil and capacitor values, PCB layout, thermal design, and communication timing. Do not infer unverified electrical limits or pin functions from a distributor listing. This page combines verified manufacturer and distributor information with engineering-oriented selection and design guidance; current pricing, stock, and detailed electrical values must be confirmed against the cited sources.

Typical Applications
BQ51013C-Q1 is suitable for 6 applications: Automotive Center-Console Wireless Charging, Portable-Device Wireless Charging Accessory, Battery-Powered Accessory Charging, Embedded Wireless-Power Module, Qi-Enabled Furniture and Desk Accessory, Battery Maintenance and Diagnostic Module.
Automotive Center-Console Wireless Charging
BQ51013C-Q1 fits an automotive center-console charging pad where the receiver must combine Qi communication, rectification, regulation, and control near the coil. Its automotive-targeted status supports design evaluation for vehicle environments, while the integrated synchronous rectifier and LDO reduce the number of receiver-side ICs. The verified family material identifies up to 5 W delivery and 93% peak AC-DC efficiency, helping designers balance usable charging power against heat in a compact enclosure. Final qualification still requires checking the exact suffix, vehicle EMC requirements, coil geometry, operating temperature, and the complete transmitter interface.
Recommended
Portable-Device Wireless Charging Accessory
The BQ51013C-Q1 is suitable for a compact charging accessory that receives power through a coil and produces a regulated DC rail for a portable device or secondary power circuit. Its fully integrated receiver architecture avoids placing separate rectification and control ICs across the receiver path, while Qi v1.3 communication control helps the receiver coordinate with a compatible transmitter. The verified family material supports up to 5 W, but the design must account for alignment distance, coil coupling, load transients, cable losses, and the thermal environment inside a phone or accessory enclosure.
Recommended
Battery-Powered Accessory Charging
BQ51013C-Q1 can form the receiver-side front end of a battery-powered accessory whose battery charger or system rail is downstream of the wireless receiver. The integrated LDO and voltage-control loops provide a regulated receiver output before power reaches the downstream charger, while synchronous rectification helps reduce conversion losses. Designers should verify the downstream battery chemistry, charge-current requirements, precharge behavior, and whether the selected power level is sufficient for the product. The supplied data does not specify a battery-chemistry profile, so the battery-management interface must be validated separately.
Recommended
Embedded Wireless-Power Module
The BQ51013C-Q1 is appropriate for an embedded wireless-power module when the receiver coil, receiver IC, output filtering, and load must be packaged into a small reusable assembly. Integration reduces external active-component count and simplifies the receiver power tree, which can help control board area and assembly complexity. The compact 20-pin VQFN package is 3.5 mm by 4.5 mm according to the verified distributor data. Thermal design, exposed-pad implementation, EMI containment, and manufacturing tolerances remain important because the module's performance depends on the coil and nearby metal structures.
Recommended
Qi-Enabled Furniture and Desk Accessory
BQ51013C-Q1 can be evaluated for a Qi-enabled desk accessory, lamp base, or furniture-mounted charging surface where a visible receiver coil benefits from a compact electronics package. The device handles receiver-side communication and regulated conversion, allowing the mechanical design to focus on coil placement and foreign-object avoidance. The verified data confirms Qi v1.3 support and up to 5 W delivery, but it does not define a complete product-level charging profile. Engineering validation should include foreign-object detection behavior, surface heating, load compatibility, standby power, and communication performance with the intended transmitter.
Recommended
Battery Maintenance and Diagnostic Module
BQ51013C-Q1 may be used in a wireless diagnostic or maintenance module that receives power without a physical connector and then powers sensors, memory, or a local processor. The integrated receiver simplifies the power-conversion stage, while the regulated output can support a downstream low-voltage system. Because the supplied evidence does not confirm standby current, output-voltage accuracy, or load-transient limits, these parameters must be obtained from the manufacturer datasheet. A practical design should include local energy storage or a downstream hold-up capacitor if interruption during alignment or transmitter hand-off is unacceptable.

- Synchronous rectification integration (vs BQ51013CRHLR)
Design Notes
Use the manufacturer PCB layout as the authority for the RHL package and receiver coil interface. Keep the receiver IC close to the coil input and place the required support components according to the datasheet application circuit; long traces can increase susceptibility to EMI and degrade communication behavior. Confirm exposed-pad connection and thermal-via recommendations from the official package drawing before fabrication.
Wireless receiver loss becomes heat in the charging surface, and the verified family material cites 93% peak AC-DC efficiency. Do not assume the family peak value applies to every coil alignment, load, or ambient condition. Validate thermal performance in the final enclosure with the intended coil, output load, transmitter power, and vehicle or accessory temperature range. Use the manufacturer thermal data for any final junction-temperature calculation.
Do not substitute BQ51013B-Q1 or another family member solely because it uses a similarly named or similar-sized package. Confirm the exact suffix, Qi protocol version, pin functions, electrical limits, exposed-pad requirements, and automotive qualification against the manufacturer datasheet. A valid replacement must be pin-to-pin and system-compatible, not merely functionally similar.
The receiver communicates with the transmitter while converting coil energy, so the coil, rectifier, regulator, and output wiring should be treated as an EMI-controlled subsystem. Follow the datasheet's recommended grounding and component placement, avoid long high-current loops, and test radiated and conducted emissions with the final enclosure and load. The retrieved data does not provide the complete EMI test setup, so those limits must come from the applicable product and regulatory requirements.
The verified family supports up to 5 W, but downstream loads can draw transients during device wake-up or battery insertion. Size the receiver output path and local decoupling from the manufacturer recommendations, and verify startup, communication handshakes, load regulation, and fault behavior. Do not assume the 5 W rating is available at every coupling distance or with every transmitter and coil combination.
Compliance Information
AEC-Q100 qualification is referenced by the verified BQ51013C-Q1 search listing, but the supplied data does not provide formal RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations.
