 Logic levels 5 V compatible

PowerSSO24

PowerSSO36

 Conformity to improved EMC requirements due

to smart H-bridge switching

Description

Features

L9959S/L9959U and L9959T are single and dual

integrated H-bridges for resistive and inductive

loads featuring output current direction and

supervising functions.

 Full path R

less than 540 mΩ

DSON

 Continuous load current > 3 A

 Operating battery supply voltage 5 V to 28 V

The PowerSSO24 houses one full H-Bridge, while

the PowerSSO36 houses both two H-Bridges that

can work in parallel, through independent input

driving commands, and one full H-bridge, by

improving PCB footprint design versus different

target applications.

 Operating V supply voltage 4.5 V to 5.5 V

 All ECU internal pins can withstand up to 18 V

 Output switching frequency up to 11 kHz

 Monitoring of V supply voltage

 SPI programmable output current limitation

from 5 A to 8.6 A (in 3 steps)

Target application ranges from throttle control

actuators to exhaust gas recirculation control

valves in automotive domain to a more general

use to drive DC and Stepper motors.

 Over temperature and short circuit protection

 Full diagnosis capability

 Fast switch-off open-drain input/output
