I am using SN6505BDBVR in one of my application to drive two transformers ( MPN : 760390014, Ratio 1:1.3) as shown below. Sequence of driving is
1. MCU enables SN6505 to drive transformer 1 (T1) in full bridge configuration. ( Secondary Load 20mA)
2. After certain time, MCU triggers BSS84P , so that Transformer 2 (T2) sees 3.3V on Vcc pin. ( Secondary Load 50mA)
**Same 3.3V is also given to MCU.
** T2 is placed 10mm away from SN6505 while T1 is placed closed to SN6505. While BSS84P is placed close to T2.
Is there any issue in below schematic while connecting 3.3V to T2 separately as it is not directly connected to VCC pin of SN6505 as shown in the datasheet.
