Part Number: UCC21732 When testing the UCC21732 chip, it was found that the Miller clamp's operation logic is incorrect. The datasheet states that it should activate when the gate voltage reaches VEE + 2V. However, during actual testing in the turn-off…
Part Number: UCC21732 Other Parts Discussed in Thread: BQ41Z90 Hello TI team,
I am working on a BBU design and considering using SiC MOSFETs as CDFET.
I would like to ask if the UCC21732 is suitable for this application.
Also, do you have any recommended…
Part Number: UCC21732 Dears,
When UCC21732 is used for high power, it drives an external totem-pole, but the Miller clamp action is detected by OUTH to detect a voltage 2V higher than VEE. After adding the driver totem-pole, OUTH is no longer the voltage…
Part Number: UCC21732 Other Parts Discussed in Thread: UCC21738-Q1 I'm considering UCC21732 for a design I'm working on which doesn't require bipolar switching. In the datasheet I can see in a couple of places that the device supports both unipolar and…
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 Dear Team,
My customer is designing the application of GaN deive with the UCC21732. They have already had " UCC217xx_XL_Calculator_Tool ". However, there is no sheet for Blanking Time Calculator on Shunt Resisor.
Is there a tool…
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 Hello,
1) In UCC21732-Q1, AIN pin is for analog voltage sense. There is a thermistor inside our IGBT module.
I want to interface that with AIN pin. Is external pull up required for…
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…
