L9959 Single and dual PMOS high-side H-bridge

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 inp.
