Part Number: UCC21732-Q1 Hello,
If only positive supply is used (to drive gate of IGBT/MOSFET) for the gate driver UCC21732-Q1; then can I short VEE and COM pins?
Part Number: UCC21732-Q1 Other Parts Discussed in Thread: UCC21732
Why there are pulses of 1KHz, 5V observed on RDY pin of UCC21732 when IN+ signal is 3 KHz, 5V and IN- is grounded?
VCC = 5V and VDD-COM = 15V, VEE-COM = -3V.
The observation is for…
Part Number: UCC21732-Q1 Other Parts Discussed in Thread: UCC21732 Hi all
I am using UCC21732 gate driver IC for SiC MOSFET. In this regard, I want to know the following:
(1) The ON state resistance of the internal FET connected across the OC pin…
Part Number: UCC21732-Q1 Hello,
What is the input impedance of UCC21372 IN+ and IN- pins?
What is the min max current required at these input pin?
Can we use RC low pass filter (R=100 ohm and C= 100pF) at input of these pins with frequency = 1…
Part Number: UCC21732-Q1 Hello, below are the queries in the timing diagram of UCC21732-Q1 as shown below -
1) How much is the time interval between "at end of t2Loff" and 0 value of gate voltage ?
2) The tblk time slot is missing in below diagram…
Part Number: UCC21732-Q1 Other Parts Discussed in Thread: UCC21530-Q1 Do the the PWM input pins non inverting and inverting pins (9 and 10), need any series resistor with capacitor (an RC filter) ?
There is direct connection given to MCU in the datasheet…
Part Number: UCC21732-Q1 Hello,
In Fig. 8-9, of UCC21732-Q1 datasheet, the R1 resistor is connected to VDD.
But in excel calculator of this get driver, R1 can be connected to VDD/OUTH.
Is it correct to connect R1 to OUTH ?
Sorry here, I am not…
