Part Number:UCC21520
Hi ,
We using UCC21520 for Motor control along with MOSFETs.
3phase motor we using Parallle MOSFET for each phase 6MOSFET using
High side Gate 3MOSFET/ /Low side Gate 3MOSFETs.
Current we using 20uF Bootstrap capacitor for 1kHz - 40kHz switching frequency. VCC=5V, VDD =12V, Bus supply 48V
We have question to select Bootstrap capacitor for our requirement. From data sheet and simulation compared to use 20uf Capacitor used now.
Please let us what we used 20uf right capacitor for Bootstraping.
Regards
