STWLC89 application related

Jimmy_chang · ‎2025-11-06

Hi,

Since we haven’t received the datasheet yet, we’d like to confirm the following information:

If the receiver side (RX) uses the STWLC89 15 W solution, what is the corresponding 15 W transmitter (TX) model?
Which Qi standards are supported by STWLC89? (Qi 2.1 or ....)

Dear Jimy_chang,

The counter part on the Tx side for a 15W EPP charging is STWBC2-HP, which is Qi 1.3 compliant.

The STWLC89 is compliant Qi 2.0 actually, it is targeted for Qi 2.1.

Please contact your distributors to get information about the datasheet and evaluation kits.
