Lead Free Status / Rohs Status
Lead free / RoHS Compliant
DESCRIPTION
The VB024 is a high voltage integrated circuit
made using SGS-THOMSON VIPower thecnology,
with vertical current flow power darlington and logic
level compatible driving circuit.
The device performs the following functions:
power stage for driving the primary side of the
ignition coil, digital signal feedback to the control
IC to indicate a predetermined current level,
automatic shut-off at maximum current, self
clamping for voltage flyback and logic level input.
