The TPD1033F is a monolithic power IC for high-side switches. The IC has a vertical MOS FET output that can be directly driven from a CMOS or TTL logic circuit (e.g., an MPU). The device is equipped with intelligent self-protection and diagnostic functions.

FEATUREs
A monolithic power IC with a new structure combining a control block (Bi-CMOS) and a vertical power MOS FET (π-MOS) on a single chip
One side of load can be grounded to a high-side switch
Can directly drive a power load from a microprocessor.
Built-in protection against thermal shutdown and load short-circuiting.
Incorporates a diagnosis function that allows diagnosis output to be read externally in the event of load short-circuiting, opening, or overheating.
Up to -10 V of counterelectromotive force from an L load can be applied.
Low on-resistance : RON = 220 mΩ (max)
Low operating current : IDD = 1 mA (typ.), (@VDD = 12 V, VIN = 0 V)
8-pin SOP package for surface mounting can be packed in tape.
