Hi
Kindly advise me on the following:
1. Are UCC21750QDWQ1/UCC21750QDWRQ1 available in the market or still in prototyping stage?
2. What is the difference between UCC21750QDWQ1 and UCC21750QDWRQ1?
3. The recommended configuration for driving half bridge with two UCC21750QDWQ1 is shown in Fig. 1 as attached (Fig. 50 in the datasheet).
I have six full bridges to drive - containing 24 SiC-MOSFETs (C3M0015065K) . I wish to minimise the I/O of the microcontroller (MCU) as much as possible by using two UCC21750QDWQ1 to drive each full bridge.
Under this now, I have two questions:
(a) Is it possible to use two UCC21750QDWQ1 to drive full bridge as shown in Fig. 2? if no, is there an alternative configuration?
(b) Still on minimising the I/O of the MCU, if I have a PWM coming from the MCU to the driver as in Fig. 3 and I need to produce its complementary (PWM') (logic inversion), is there any component (IT product) to achieve this?
N.B: If I could achieve (a) and (b), then I'll be able to use two I/Os instead of four (now saving two I/O channels!).
Peradventure I am not channelling my enquiry through the right channel, kindly help me direct it to the appropriate department or personnel. I look forward to getting a response soon. Thank you soon.
