MULTIPLE MULTIFUNCTION VOLTAGE REGULATOR

STMicroelectronics 

L5952

voltage may not be present.

Note - example 1 & 2 don’t use the OUT2 and OUT6 bytes in the initial set procedure, since these two bytes are not related to the setting of

output voltages

< Example 2B - autoincrement mode - >

power on Vin = ON All output OFF (at RESET = “L”)

release reset RESET = “H”

start I2C

initial set

stop I2C

start I2C

1000 1000 Chip address

0001 0001 OUT3 subaddress, autoincrement ON

0000 0010 OUT3 data (8.3V, OFF)

0000 0010 OUT4 data (7.0V, OFF)

0000 0000 OUT5 data (3.3V, OFF)

set turn-on

stop I2C

1000 1000 Chip address

0001 0010 OUT4 subaddress, autoincrement ON

0000 0011 OUT4 data (7.0V, ON)

0000 0001 OUT5 data (3.3V, ON)

0000 0001 OUT6 data (ON)

0000 0001 OUT2 data (ON)

0000 0011 OUT3 data (8.3V, ON)

The autoincrement implements a counter by 5, this means that during autoincrement the next date after out 6

byte will be OUT2 date byte.

In the example are refreshed in sequence the bytes: OUT4 - OUT5 - OUT6 - OUT2 - OUT3
