Part Number: UCC2626 Hello,
I am working on a bldc motor project. The issue I am having is that the duty cycle will max out at ~50% and PWM_I will max out at 5V(does not go any higher). The duty cycle maxes at 50% because the PWM_NI is a triangular wave…
Part Number: UCC2626 Hi!
We are using UCC2626 for motor control and current limit for motor. We would like to know what happens when the motor is turned off after reaching the maximum current limit. Will it turn the MOSFET switvches off? If so, after…
Thank you again for your help. Likewise, I've also been struggling to find more information about this part. The app note does help, and I used a similar one, but I am not sure if it is applicable for motor drives. Please let me know if you could provide…
Hi Annie,
From looking at the pkg offerings of each UCC2626 vs UCC3626 device, they share some of the same packages (DW, PW)
Looking at their datasheets online, I think they even share a common datasheet -> with the main difference being temperature…
Part Number: UCC2626 Hi,
We are using UCC2626PW motor control IC. While simulating thermal Analysis at 75°C, we are getting component temperature of 84°C which is closed to operating temperature of the IC which is 85°C. Does that mean if the temperature…
Part Number: UCC2626 Hello,
I wanted to know what happens when current sense after gain of 5 (IOUT in the IC) goes above the current limit set by the user (OC_REF). Are all outputs disabled?
It has not been mentioned anywhere in the datasheet.
Regards…
Part Number: UCC2626 Hello,
I am using UCC2626 MOTOR CONTROLLER IC to drive a bldc motor with a current capability of 32A. This inquiry is regarding the input voltage range of SNS_I and SNS_NI pins.
The motor currents are sensed using bidirectional current…
Adam, Thanks. I have not seen any technical responses regarding my question about internal protection at the Vref pin of UCC2626.. However, this issue can be considered CLOSED. The need to ground the capacitor I mentioned at the Vref (pin2) no longer exists…
Part Number: UCC2626 Hello , I am performing stress analysis on a circuit and I am looking for Thermal Resistance to Air for the Part UCC2626 used in the circuit. I couldn't get the thermal resistance to air in the datasheet provided by TI. Can anyone…
