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-

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

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.

This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice.
