DESCRIPTION
The L6213 is an IC containing a S.M.P.S. delivering 1A at a voltage of 5V and a section designed
to drive a solenoidwithacurrent up to5A.
The device is realized in BCD mixed technology,
which combines isolated DMOS power transistor
with CMOSand Bipolar circuitson the samechip.
The SMPSsection can deliver 1A DC with anout-
