DESCRIPTION
The L6213 is an IC containinga S.M.P.S. deliver-
ing 1A at a voltage of 5V and a section designed
to drive a solenoidwith 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 SMPSsection can deliver 1A DC with anout-
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-
tronictypewriter.
Thesolenoidoutputsectioncontainsa high sideand
a low side DMOS, which R
DS ON
are optimized for
high side chopping.The current rising slope is exter-
nallyprogrammablethroughanexternalcapacitor.
The level of hysteresis of the current can be
changedthroughan externalresistor.
The device is supplied in Powerdip 16+2+2, and
use the four center pins to conduct heat to the
printed circuit.
This isadvanced information on anew product now in development or undergoing evaluation. Details are subject to change without notice.
