Part Number:BQ500412
Hello TI Team,
Our product uses the BQ500412 for wireless charging. There is a small unwanted ~1.08V impulse signal (~4ms duration) on the snooze line as shown below.
Yellow - VDD3
Blue - Capacitor in RC circuit responsible for Snooze (C61 in bq500412-EVM)
Violet - Reset
Teal - Snooze Signal
Some of our boards do not experience this signal, however, some do. The unwanted signal was causing the BQ500412 to get "stuck" as Q7 (in EVM) responded to this signal. My question is - what is causing this signal?
Many Thanks,
Edgar
