3 Description
The input side is isolated from the output side with
SiO2 capacitive isolation technology, supporting up to
1.5-kVRMS working voltage, 12.8-kVPK surge immunity
with longer than 40 years Isolation barrier life, as well
as providing low part-to-part skew, >150V/ns
common mode noise immunity (CMTI).
The UCC21732-Q1 includes the state-of-art
protection features, such as fast overcurrent and
short circuit detection, shunt current sensing support,
fault reporting, active miller clamp, input and output
side power supply UVLO to optimize SiC and IGBT
switching behavior and robustness. The isolated
analog to PWM sensor can be utilized for easier
temperature or voltage sensing, further increasing the
drivers' versatility and simplifying the system design
effort, size and cost.

The RST/EN serves two purposes:
1) Enable / shutdown of the output side. The FET is turned off by a general turn-off, if terminal EN is set to
low;
2) Resets the OC condition signaled on FLT pin. if terminal RST/EN is set to low for more than 1000ns. A
reset of signal FLT is asserted at the rising edge of terminal RST/EN.
For automatic RESET function, this pin only serves as an EN pin. Enable / shutdown of the output side. The
FET is turned off by a general turn-off, if terminal EN is set to low.

Apply creepage and clearance requirements according to the specific equipment isolation standards of an application. Care must be
taken to maintain the creepage and clearance distance of a board design to ensure that the mounting pads of the isolator on the printed
circuit board (PCB) do not reduce this distance. Creepage and clearance on a PCB become equal in certain cases. Techniques such as
inserting grooves and ribs on the PCB are used to help increase these specifications.
This coupler is suitable for safe electrical insulation only within the safety ratings. Compliance with the safety ratings shall be ensured by
means of suitable protective circuits.
Testing is carried out in air or oil to determine the intrinsic surge immunity of the isolation barrier.
Apparent charge is electrical discharge caused by a partial discharge (pd).

6.8 Safety Limiting Values
The safety-limiting constraint is the maximum junction temperature specified in the data sheet. The power dissipation and
junction-to-air thermal impedance of the device installed in the application hardware determines the junction temperature. The
assumed junction-to-air thermal resistance in the Thermal Information table is that of a device installed on a high-K test board
for leaded surface-mount packages. The power is the recommended maximum input voltage times the current. The junction
temperature is then the ambient temperature plus the power times the junction-to-air thermal resistance. These limits vary
with the ambient temperature, the junction-to-air thermal resistance, and the power supply voltages in different applications.
