what is built on integrated circuits and carries the electrical current?
The VB525SP-E is a high voltage power. integrated circuit made using the. STMicroelectronicsâ¢ VIPowerâ¢ M1-3. technology, with Darlington and logic level. compatible vertical current flow power driving. circuit. The enable pin allows to externally block the. switch when the input is on. A built-in protection. circuit for coil current limit ing and collector voltage. clamping allows the device to be used as a smart, high voltage, high current interface in advanced. electronic ignition systems.
