Description
L9959S/L9959U and L9959T are single and dual integrated H-bridges for resistive and inductive loads featuring output current direction and supervising functions.
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.
Features
• Full path RDSON less than 540 mΩ

• Operating battery supply voltage 5 V to 28 V
• Operating VDD 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 VDD supply voltage
• SPI programmable output current limitation
from 5 A to 8.6 A (in 3 steps)
• Over temperature and short circuit protection
• Full diagnosis capability
• Fast switch-off open-drain input/output
• Current-monitoring with current feedback
output signal CF
