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…
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…
Part Number: UCC2626 Hello,
For the UCC2626DW, I have the following questions:
1. Which level of voltage level should we aim for as the input to the PWM-I pin? Do we target 5V (mid-way between 2.5V and 7.5V) at the rated speed of the motor to give…
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.

Hello Adam Sidelsky, thanks for the looking into the problem.
I'm in the design phase of my project and that why I wanted that clarification regarding the mentioned parameter of UCC2626 IC before I go for realization of the project. As described before…
Part Number: UCC2626 I am using the Vref 5 Volt output (pin 2) to set a current limit reference voltage. Can the Vref pin have a 47uF tantalum capacitor connected to ground and be safe for the IC chip when the input VDD supply is shut down? Is there protection…
