Part Number: BQ51003 Hi,
Regarding to the post related to "BQ51003: No power transfert when strong coupling just high voltage large pulses for VRECT.", I have changed the communication capacitors for 4.7 nF, 6.2nF, 8.2nF and 10 nF. Initialy the communication…
Part Number: BQ51003 Tool/software: This is a follow up to my previous post about tuning the BQ51003 for a small coil.
We completed the tuning and shielding recommended by the last post and are now noticing significant thermal issues with the coil and…
Part Number: BQ51003 Hi Team
could you help on this SCH review?

it's a earphone project and this is for the box in the earphone. we hope it can support Qi wireless charge.
plan…
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 Wuerth…
Other Parts Discussed in Thread: BQ51003 Hi there!
We are developing a small wearable product with a coil footprint of ~16x28mm, modulo some space for case walls and fastener holes.
We have tuned our design based on the FAQ and are still having issues getting…
Part Number: BQ51003 Dear TI support team, similar to the existing " BQ51050B: Tool to read QI charging communication " thread in this forum, I am looking for a tool to monitor the communication between the transmitter and the receiver in a Qi system…
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 pin…
Leonhard Renk said: Is there even an AC component to be expected for these two signals or does it result from the magnetic field coupling into the signals? Also, what are the precise thresholds for these two pins to trigger the shutdown of the output voltage…
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…
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 from…
