TPD1033F
High-side Power Switch for Motors, Solenoids, and Lamp Drivers
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
z 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
z One side of load can be grounded to a high-side switch
z Can directly drive a power load from a microprocessor.
z Built-in protection against thermal shutdown and load
Weight: 0.08 g (typ.)
short-circuiting.
z Incorporates a diagnosis function that allows diagnosis output to be read externally in the event of load
short-circuiting, opening, or overheating.
z Up to -10 V of counterelectromotive force from an L load can be applied.
z Low on-resistance
: R_ON = 220 mΩ (max)
z Low operating current : I_DD = 1 mA (typ.), (@V_DD = 12 V, V_IN = 0 V)
z 8-pin SOP package for surface mounting can be packed in tape.
