VB125ASPTR-E

High voltage ignition coil driver power integrated circuit

Features

■ ECOPACK®: lead free and RoHS compliant

■ Automotive Grade: compliance with AEC

guidelines

■ Primary coil voltage internally set

■ Coil current limit internally set

■ Logic level compatible input

■ Battery operation

■ Single flag-on coil current

■ Temperature compensated high voltage clamp

Description

The VB125ASPTR-E is a high voltage power

integrated circuit made using the

STMicroelectronics™ VIPower™ M1-2

technology, with vertical current flow power

darlington and logic level compatible driving

circuit.

The VB125ASPTR-E can be directly biased by

using the 12 V battery voltage, thus avoiding to

use a low voltage regulator. It has built-in

protection circuit for coil current limiting and

collector voltage clamping. It is suitable as smart,

high voltage, high current interface in advanced

electronic ignition system.
