BQ500210RGZT Overview
A wireless power transmitter manager is a specialized power-management IC that coordinates sensing, communications, pulse-width modulation, and power-stage control for wireless charging equipment. Its hierarchy is wireless power controller, transmitter controller, power-management IC, and semiconductor. Unlike a general-purpose buck converter, this device is intended to manage an inductive power-transfer link operating under wireless-power-consortium protocols.
The verified product information identifies the BQ500210 as an IF transmitter and a dedicated digital controller that periodically pings the surrounding environment for devices available for powering and monitors communication from the power receiver. Its Qi compliance and communication-monitoring functions help the base station detect receiver presence, exchange required control information, and adjust the wireless-power operating process.
The controller operates from 3 V to 3.6 V and supports an operating-frequency range of 110 kHz to 205 kHz. Its 48-VQFN package is suitable for compact transmitter-PCB designs. The exposed-pad construction provides a thermal and electrical land-pattern requirement that must be implemented according to the manufacturer datasheet rather than treated as an ordinary 48-lead non-exposed package.
Typical uses include Qi-compatible charging pads, embedded wireless charging surfaces, sealed charging products, furniture-integrated chargers, and hermetically sealed devices. Because the part is specifically intended for hermetically sealed devices and single-channel base stations, system-level matching between the controller, transmitter driver, resonant tank, receiver, and coil is essential.
When laying out a transmitter board, preserve the recommended power and signal-loop topology and place high-current switching paths compactly. Keep sensitive communication and sensing paths away from resonant-current edges, use the manufacturer-recommended thermal-pad implementation, and validate the final coil, driver, switching frequency, and receiver combination rather than assuming that functionally similar controllers are interchangeable.
This page consolidates the verified Texas Instruments product description, distributor listing information, package details, operating ranges, and cross-reference findings. It also separates verified facts from missing electrical details and avoids presenting unverified alternatives as drop-in replacements, helping engineers identify what must still be checked against the manufacturer datasheet.

Typical Applications
BQ500210RGZT is suitable for 6 applications: Single-Channel Qi Charging Pad, Hermetically Sealed Charging Product, Furniture-Integrated Wireless Charger, Inductive Charging Surface, Consumer Wireless Power Base, Industrial Contactless Power System.
Single-Channel Qi Charging Pad
The BQ500210RGZT fits a Qi charging pad because it is identified as a Generation 2, single-channel wireless power transmitter controller operating from 3 V to 3.6 V and across 110 kHz to 205 kHz. Place it beside the transmitter driver, MOSFET power stage, resonant tank, and receiver-compatible coil so it can coordinate periodic pinging and communication monitoring. The system benefit is protocol-aware control rather than a simple fixed-frequency switching sequence. Its tradeoff is that the controller is specialized: coil inductance, driver timing, power-stage ratings, and receiver behavior must be validated together as one wireless-power design.
Recommended
Hermetically Sealed Charging Product
The BQ500210RGZT is specifically identified for hermetically sealed devices, making it relevant to wireless charging assemblies where exposed contacts or a conventional connector would be undesirable. Its verified 3–3.6 V digital-control supply and 110–205 kHz operating range support integration with a sealed inductive power-transfer stage. Designers should pay particular attention to enclosure materials, coil coupling distance, heat dissipation, and the effect of the enclosure on communication and power-transfer performance. The controller manages the protocol process, but successful operation still depends on the complete transmitter and receiver implementation.
Recommended
Furniture-Integrated Wireless Charger
A furniture-integrated charger can use the BQ500210RGZT when the design needs automatic receiver discovery and Qi-compatible transmitter behavior without exposed charging contacts. The controller’s verified periodic environment-ping behavior helps identify available receivers, while its communication monitoring supports receiver interaction during power transfer. Integrating the 48-VQFN controller into a thin surface mount still requires adequate exposed-pad copper, a suitable coil geometry, and separation from sensitive analog or low-power circuitry. The 110–205 kHz band should be checked against the chosen driver and resonant network before layout release.
Recommended
Inductive Charging Surface
The BQ500210RGZT is appropriate for an inductive charging surface that presents one wireless-power region and needs Qi-compatible discovery and communication management. Use it with the manufacturer-recommended transmitter topology and a resonant coil tuned for the verified 110–205 kHz operating range. Because the controller is supplied in a 48-VQFN 7 mm × 7 mm package, PCB space can be allocated close to the power stage, while exposed-pad connections must follow the official package and layout guidance. Validation should cover coupling tolerance, foreign-object behavior, standby power, thermal conditions, and receiver startup across the intended enclosure.
Recommended
Consumer Wireless Power Base
The BQ500210RGZT can serve as the control center of a consumer wireless power base when the transmitter is designed around a single Qi channel. Its verified digital architecture separates wireless communications and discovery functions from the external power-switching stage, allowing the implementation to be tailored to the selected driver and coil. Compared with a basic inductive driver, the BQ500210RGZT supports a protocol-oriented pinging process and receiver communication monitoring. The system designer remains responsible for operating voltage, switching losses, current capacity, thermal design, foreign-object management, and compliance of the finished charger.
Recommended
Industrial Contactless Power System
The BQ500210RGZT may be evaluated for a contactless industrial power system when the power level, receiver protocol, and operating environment are compatible with its verified single-channel Qi transmitter role. The 3–3.6 V controller supply supports conventional low-voltage digital rails, while the 110–205 kHz operating range defines the starting point for the inductive link. Industrial adoption requires additional validation beyond device specifications, including insulation coordination, enclosure tolerances, temperature rise, transient immunity, and the availability of the external power stage. Do not infer safety certification or industrial qualification from the distributor listing.

Selection Guide
Design Notes
Use the official BQ500210RGZT package drawing and datasheet layout guidance for the 48-VQFN exposed pad. The verified data confirms a 7 mm × 7 mm VQFN with an exposed pad, but it does not provide the land pattern or pin table. Do not infer pad dimensions from the package body alone; verify pin numbering, thermal-via recommendations, solder-mask clearance, and paste geometry before releasing artwork.
Design the 3–3.6 V controller rail separately from the higher-current switching path. Keep the controller’s decoupling network and ground return close to its supply pins, and follow the manufacturer’s recommended component values. The supplied evidence does not include absolute maximum ratings or recommended capacitor specifications, so those values must be taken directly from the official datasheet rather than estimated.
Treat the resonant tank, transmitter coil, driver, and power MOSFETs as a coupled high-current system. Keep switching-loop area compact and route sensitive sensing or communication paths away from coil-current edges and switching nodes. Validate the layout with current-probe measurements and electromagnetic/emission testing; the verified BQ500210RGZT data does not specify trace widths, loop inductance, or emission limits.
Compliance Information
The verified search identifies Qi and WPC 1.0.2 functionality but does not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals documentation.
