DESCRIPTION (CONT.)

The input pin threshold of the UCC27518 and UCC27519 are based on CMOS logic where the threshold voltage

excellent noise immunity and allows users to introduce delays using RC circuits between the input PWM signal

and the INx pin of the device.

The UCC27518 and UCC27519 also feature a floatable enable function on the EN pin. The EN pin can be left in

a no connect condition, which allows pin-to-pin compatibility between the UCC27518, UCC27519 and the

TPS2828, TPS2829 respectively. Enable pin threshold is a fixed voltage threshold and does not vary based on

V.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
