Product details
Overview
BQ51014YFPR from Texas Instruments is a Qi v1.0–compliant integrated wireless power receiver IC for portable electronics, delivering a regulated 5 V / 1.5 A output from inductively coupled AC input. It integrates full synchronous rectification, dynamic rectifier control, adaptive communication current limiting, and 15 V input overvoltage protection - enabling compact, high-efficiency (93% peak) contactless charging in smartphones and wearables.
For engineers reviewing the BQ51014YFPR datasheet, BQ51014YFPR pinout, BQ51014YFPR application, or BQ51014YFPR equivalent, key selection considerations include its DSBGA-20 (1.9 × 3 mm) package, WPC-compliant bidirectional communication via COM1/COM2 pins, programmable termination (CS100) support on TERM pin, and adapter-input multiplexing capability with AD/AD-EN interface.
Technical Context
The BQ51014YFPR implements a closed-loop Qi v1.0 communication stack with 2-kbps differential bi-phase signaling, using COM1 and COM2 for capacitive or resistive load modulation to transmit error packets, identification, and end-power-transfer commands to the transmitter (e.g., bq500210). Its digital controller dynamically adjusts the RECT voltage threshold across four load-dependent levels (5.11 V to 7.08 V) to optimize transient response without external compensation.
It combines a low-RDS(on) synchronous rectifier (1.5 Ω typical for COM1/COM2), an internal LDO regulator, and hardware-based current limiting (programmable via ILIM resistor), all operating within a –40°C to +125°C junction range. Thermal shutdown at 155°C and NTC/CTRL pin support for temperature monitoring and fault reporting are integrated.

Equivalent & Alternatives
The following parts are listed as comparable options for similar wireless power receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| bq51013AYFPR | No TERM pin; CS100 termination not supported; AD OVP disabled; communication current limit fixed at 400 mA | Suitable for cost-sensitive receivers where battery-full signaling is handled externally | Select if CS100 and adapter OVP are unnecessary; lower BOM cost but reduced feature set |

FAQ
What is the primary function of the BQ51014YFPR in a wireless charging system?
The BQ51014YFPR serves as a complete Qi v1.0–compliant wireless power receiver IC, performing AC-to-DC conversion via integrated synchronous rectification, regulating a precise 5 V output, executing bidirectional WPC communication through COM1/COM2, and managing power-path arbitration between wireless and wired (adapter) inputs. It replaces discrete rectifier, LDO, and communication controller functions in portable devices.
Does the BQ51014YFPR support programmable charge termination (CS100)?
Yes, the BQ51014YFPR uniquely supports programmable CS100 via its TERM pin - a feature absent in the bq51013A. By connecting an external resistor RTERM = %IMAX × 200 Ω/%, designers can set precise termination thresholds (e.g., 100 mA for 1 A max current), enabling accurate battery-full detection without host MCU intervention.
How does the BQ51014YFPR handle adapter input integration?
The BQ51014YFPR uses AD and AD-EN pins to detect and manage wired adapter input: when AD voltage exceeds 3.6 V, wireless charging disables and AD-EN drives low to control an external PFET. Critically, the BQ51014YFPR includes dedicated 12.5 V adapter OVP - a safety feature not present in bq51013A - preventing damage during overvoltage events on the adapter rail.
What package type and dimensions does the BQ51014YFPR use?
The BQ51014YFPR is packaged in a DSBGA-YFP (20-ball, 1.9 × 3 mm, 0.4 mm pitch) with bottom-side solder balls and an exposed thermal pad. This ultra-compact, low-profile package is optimized for thin mobile devices where board area and Z-height are constrained - matching the footprint of bq51013AYFPR for drop-in compatibility in existing layouts.
Is the BQ51014YFPR recommended for new designs?
No - Texas Instruments explicitly marks the BQ51014YFPR as "Not Recommended For New Designs" in its official documentation. While fully functional and supported for existing production, new projects should evaluate successors such as the bq51222 (Qi v1.2.4, up to 15 W) or newer wireless power receivers aligned with current WPC specifications and enhanced safety features.
