BQ51013CRHLR 개요
A wireless power receiver is the secondary-side device in an inductive charging system. It receives alternating energy from a transmitter coil, converts that energy to DC, regulates the output, and communicates with the transmitter to establish and maintain Qi power transfer. Within the hierarchy wireless power receiver -> power management IC -> battery-management subsystem -> portable-device charger, the BQ51013CRHLR concentrates the power-conversion and negotiation functions needed for a compact receiver design.
The verified data lists full synchronous rectification, output-voltage conditioning, WPC v2.0 communication control in one search result, and WPC Qi v1.3 compliance in the Texas Instruments product listing. Only one IC is required between the receiver coil and output according to the indexed datasheet description. These features can reduce external circuitry and simplify portable-device charger development while supporting a maximum output class of 5W.
The receiver architecture uses an integrated rectification and regulation stage rather than relying on a discrete diode and separate regulator implementation. Full synchronous rectification can reduce conduction loss compared with a simple diode path, while the reported 93% peak efficiency quantifies conversion performance at its best operating point. Actual efficiency depends on coil coupling, input power, output voltage, load, temperature, and PCB layout, so the peak rating should not be treated as a constant under every condition.
Typical uses include 5W wireless charging for wearables, earbuds, mobile accessories, and portable consumer products. The compact package supports space-constrained receiver hardware, while the -40 °C to 125 °C specified temperature range covers industrial-temperature design needs. A product designer still must validate the selected receiver coil, output network, thermal performance, foreign-object behavior, and enclosure geometry.
The primary design consideration is preserving coil coupling and high-frequency electrical performance. Follow the manufacturer layout guidance, keep the receiver coil and compensation network close to the IC, provide the required output capacitance, and route high-current paths with minimal loop area. Wireless-power efficiency is a system result involving the transmitter, coil, alignment, shield, load, and board implementation, not only the receiver IC.
This page consolidates the verified distributor listings, Texas Instruments product information, package details, efficiency claims, pricing indication, and design considerations into one engineering reference. It also clearly separates verified facts from unavailable specifications and avoids presenting unverified substitute parts as drop-in replacements.

일반적인 애플리케이션
BQ51013CRHLR 적합 용도: 6 애플리케이션s: Wireless Charging for Wearables, Earbuds Charging Case, Mobile Accessory Charging, Qi-Compatible Portable Charger, Industrial Portable Charging Module, Battery-Free Sensor Charging.
Wireless Charging for Wearables
The BQ51013CRHLR suits a wearable receiver because it combines a 5W wireless power receiver, full synchronous rectification, output-voltage conditioning, and Qi communication control in a compact 3.5 mm by 4.5 mm RHL VQFN. Place the IC in the secondary-side charging path between the receiver coil and the wearable power rail to reduce discrete conversion circuitry. Peak AC-DC efficiency reaches 93% under favorable conditions, but real efficiency also depends on coil alignment, coupling, shielding, load, and enclosure geometry.
Earbuds Charging Case
An earbuds case is a natural fit for the BQ51013CRHLR because the receiver can provide up to 5W while integrating rectification, regulation, and WPC Qi v1.3 communication in one IC. The small RHL VQFN leaves board area for the receiver coil, storage circuitry, and battery-related passives. Designers should optimize the coil-to-shield spacing and account for metallic case geometry, foreign-object detection, output ripple, and the thermal behavior of a repeatedly charged internal battery.
Mobile Accessory Charging
The BQ51013CRHLR can form the receiver core of a 5W mobile accessory such as a battery pack, charging base, or portable power accessory. Its full synchronous rectifier and output-voltage conditioning reduce the number of stages required between the RX coil and regulated output, while the reported 93% peak efficiency improves available power headroom. Final charging behavior must use the intended battery chemistry and protection circuitry, with validation across coil offsets, load transients, temperature, and the transmitter operating range.
Qi-Compatible Portable Charger
For a portable Qi charger, the BQ51013CRHLR integrates the secondary-side digital control needed for WPC Qi v1.3 communication together with receiver AC-DC conversion and output regulation. Its 20-pin RHL VQFN package supports compact layouts, but successful operation still depends on an approved transmitter, receiver coil, compensation network, and output network. Test power negotiation, foreign-object handling, charging current, standby loss, and thermal rise across the intended receiver-to-transmitter alignment range.
Industrial Portable Charging Module
The BQ51013CRHLR's verified -40 °C to 125 °C operating range makes it a candidate for a sealed industrial portable charging module where inductive coupling avoids an exposed connector. The 5W output and integrated Qi communication can support maintenance equipment, handheld instruments, or sensor modules. Qualification must cover the complete module rather than the IC alone, including enclosure heat transfer, condensation, foreign objects, cable-free alignment, battery aging, and sustained-load behavior across temperature extremes.
Battery-Free Sensor Charging
The BQ51013CRHLR can power a rechargeable or energy-storage sensor module through a wireless receiver stage. Up to 5W output is sufficient for many low-to-moderate-power sensor systems, and the integrated communication control coordinates power transfer with the transmitter. Engineer the output rail around the sensor's peak demand and storage capacitance; a receiver optimized only for steady-state efficiency may still experience voltage droop during radio transmission, sensor sampling, actuator motion, or battery recharge bursts.

설계 노트
Use the official BQ51013C reference layout and land pattern for the RHL VQFN rather than a generic 20-QFN footprint. Place the receiver coil, compensation network, and sensitive communication traces according to the manufacturer layout because their relative positions influence magnetic coupling and control stability. Inspect the exposed pad, paste pattern, solder mask, and assembly process under the exact package drawings because package naming alone does not establish land-pattern compatibility.
Keep high-current and high-frequency switching loops compact and provide a low-impedance ground path between the relevant power stage and exposed thermal pad. Route away from sensitive antenna, audio, and sensor nodes where possible, and follow the manufacturer's keepout and copper guidance for the receiver coil area. Poor return-current paths can increase radiated emissions, disturb voltage regulation, and reduce margin during transmitter or load transitions.
Thermal design must account for receiver IC loss, coil loss, nearby circuitry, and the enclosure rather than using only the 93% peak-efficiency claim. At 5W output, even a hypothetical 90% conversion efficiency would correspond to approximately 0.56W receiver-path loss, calculated as 5W divided by 0.90 minus 5W; this is an engineering estimate, not a BQ51013CRHLR datasheet specification. Verify junction temperature, copper spreading, and enclosure temperature experimentally.
Do not infer a drop-in replacement from the BQ51013 family name or a generic 20-pin VQFN package. Verify exact RHL dimensions, exposed-pad geometry, pin assignment, compensation values, Qi protocol revision, output limits, and application reference design. Also do not assume that 93% peak efficiency applies at minimum coupling or maximum load; evaluate alignment tolerance, foreign objects, standby consumption, startup behavior, and thermal conditions in the finished enclosure.
