Parallel 4-wheel skates are skating classics. In addition to having a beautiful design, they are very comfortable skates. Before continuing, you should know that they are also known as quad skates, roller skates, and parallel skates, so if you see these names in the text, we are referring to the same ones. Who are 4-wheel …
The L6207 device is a DMOS dual bridge designed for motor control applications and implemented using BCD technology, which combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The unit also includes two independent PWM current controllers with constant turn-off time for performing chopper regulation. The L6207 devices come in …

The L6572 is a high voltage half-bridge driver for current regulating, quasi-self-excited oscillating ballasts. It contains all the functions necessary for preheating the filament, igniting and operating the fluorescent lamp. During normal operation of the lamp, the ballast operates with a nominal or reduced resonant current, resulting in a nominal or reduced light output of …
