VB526SP-E中文资料High voltage ignition coil driver power integrated circuit数据手册ST规格书

描述 Description

The VB526SP-E is a high voltage power integrated circuit made using the STMicroelectronics™ VIPower™ 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 limiting and collector voltage clamping allows the device to be used as a smart, high voltage, high current interface in advanced electronic ignition systems. If the input signal from the microcontroller happens to remain high, the device protects itself against overheating by forcing collector current to smoothly decrease (low voltage clamp feature) to avoid undesired spark.
