DESCRIPTION
The L6213 is an IC containing a S.M.P.S. deliver-
ing 1A at a voltage of 5V and a section designed
to drive a solenoid with a current up to 5A.
The device is realized in BCD mixed technology,
which combines isolated DMOS power transistor
with CMOS and Bipolar circuits on the same chip.
The SMPS section can deliver 1A DC with an out-

MULTIPOWER BCD TECHNOLOGY
Powerdip 16+2+2
put voltage of 5V, including current limiting, reset
and power fail for microprocessor and thermal
protection.
The solenoid driver section is designed for high
current applications like hammer driver in elec-
tronic typewriter.
The solenoid output section contains a high side and
a low side DMOS, which RDS ON are optimized for
high side chopping. The current rising slope is exter-
nally programmable through an external capacitor.
The level of hysteresis of the current can be
changed through an external resistor.
The device is supplied in Powerdip 16+2+2, and
use the four center pins to conduct heat to the
printed circuit.
