L6213 Datasheet - STMicroelectronics

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 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 output voltage of 5V, including current limiting, reset and power fail for microprocessor and thermal protection.
