Part Number: UCC21222-Q1 Other Parts Discussed in Thread: UCC21540-Q1 , , UCC21520-Q1 , UCC20225-Q1
Hey Team,
I have a customer that is deciding between the UCC21222-Q1, UCC21520-Q1, and UCC21540-Q1 for a Belt Start Generator (BSG) automotive application. …
Part Number: UCC21222-Q1
Dear Team,
We are using UCC21222QDQ1 half bridge IC for 3 phase inverter configuration.
We use 4 parallel mosfets and are concerned in the supply current requirement of the gate drive interface.
Switching frequency is 10 kHz,…
Part Number: UCC21222-Q1 Hi,
I am using UCC21222-q1 in our project application. Following is the test condition used: VDDA= 15V; VCCI = 5V; INA = INB = 3.3 V at 20kHz switching frequency with 87% duty cycle on INA and 1 % duty cycle on IN B. However it…
Part Number: UCC21222-Q1 Hello Team,
Good day. Hope you are safe and healthy.
Regarding the internal resistance tolerance, Its understood that its 20%. (As per the information from Ti). Here I have one more querry.
The above 20% tolerance is considered…
Part Number: UCC21222-Q1 Hi Team,
I could see the propagation delay (min 28ns and max 40ns) is given for 0 load capacitance.
I'm trying to measure the same with mosfet mounted.
Do we have a curve with propagation delay vs load capacitance.
Part Number: UCC21222-Q1 Hi,
The delay of diable pin is given to be 36ns to 50ns.
once the voltage on DIS reaches its threshold (or) 50%, it will take 36ns to 50ns for output to reach 90% of its threshold - refer figure 29 of datasheet.
But in actual…
Part Number: UCC21222-Q1 Hello,
What would be the tolerance of the Internal resistors at the pins INA, DIS & INB?
Internal resistance values:
INA ==> 200K ==> tol ?
DIS ==> 50K ==> tol?
INB ==> 200K ==> tol?
Waiting for valuable…
Part Number: UCC21222-Q1 I am using UCC21222-Q1 in a high power synchronous buck converter for an automotive application. OUTA is connected to the gate on the high side MOSFET and powered by an isolated power supply. OUTB is connected to the gate of the…
Part Number: UCC21222-Q1 Other Parts Discussed in Thread: UCC21520-Q1 Hello Team,
I am using Ucc21222-Q1 for our application.
The absolute maximum voltage of VDDA and VDDB pin is mentioned to be 20V in datasheet.
In one of our application, in a worst…
