VB525SP-E

High voltage ignition coil driver power integrated circuit

Features

current

Description

The VB525SP-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.
