  • BQ51003: Thermal shutdown

    Part Number: BQ51003 Hi We where trying to derive a thermal shutdown at around 60 degrees C, to that end we used the equations on page 23 of the data sheet https://www.ti.com/lit/ds/symlink/bq51003.pdf, and arrived at the two resistor values (denoted…

  • BQ51003: Issues to initiate stable power transfer with certain Qi transmitters

    Part Number: BQ51003 Tool/software: Dear TI support team, I am working on a design including the BQ51003 as a wireless QI receiver. It consists of the RX coil (760308101214 from Wuerth Elektronik), two ferrite sheets of 0.3mm thickness (354006 from…

  • BQ51003: Is it OK to leave the two RECT pins unconnected?

    Part Number: BQ51003 Other Parts Discussed in Thread: TIDA-00318 , Is it OK to leave the two RECT pins unconnected? The datasheet shows the two RECT pins connected together, but not connected to anything else on p. 34, 11.2 Layout Example. But the…

  • BQ51003: BQ51003

    Part Number: BQ51003 Hi, Are there any Qi transmitters still active in TI's portfolio? All I can seem to find is NRND. Thanks, Marc-Alexandre

  • BQ51003: Max Output Capacitance

    Part Number: BQ51003 Hello, Is there a "maximum" output capacitance this device can support on the OUT pin? Are there any risks of using "too much" capacitance? Thanks, Michael

  • BQ51003: BQ51003 presents as FOD after charging

    Part Number: BQ51003 Other Parts Discussed in Thread: BQ25101 , Bill Jones I see you've answered similar questions to this before and though I would ask you. We have a BQ51003 (with a custom PCB receiving coil), and a downstream BQ25101 charging a battery…

  • BQ51003: No power transfert when strong coupling just high voltage large pulses for VRECT.

    Part Number: BQ51003 Hi, I have designed a wireless receiver based on the BQ51003 for delivering 50 mA. Our coil is the one defined in the Qi V1.3 specification RX reference design page 14 except its thickness (0.1 mm, 1 layer and 22 turns). Its value…

  • BQ51003: Tuning resonant circuit for BQ51003

    TI Thinks Resolved
    Part Number: BQ51003 Hi, We are trying to design a wireless charger using BQ51003. I understand how to calculate C1 and C2 on Rx resonant circuit but I don't know how to measure resonant frequency and adjust an actual sample. How did you measure…

  • BQ51003: Q-Factor

    Part Number: BQ51003 Hello, In section 9.2.1.2.2 , it states that the Q-factor must be greater than 77, however my customer is seeing a Q-factor of ~69 with their coil/ferrite. How was requirement of greater than 77 determined? What are the potential…

  • BQ51003: Charge rate

    Part Number: BQ51003 Other Parts Discussed in Thread: BQ51013 , BQ25120A , , BQ25100 , TIDA-00318 Hi Team, I have a question regarding this device. I would like to know what is the charging current range of BQ51013/B? Also, I plan to use BQ25120A…
