High side power switch

TPD1055FA is a High-side switch of a P channel DMOS

output. It is monolithic power IC that can be driven directly

from a CMOS or TTL logic circuit (MPU etc.), and was

equipped with the intelligent function of protection and

diagnosis.

Features

 A monolithic power IC with a structure combining a control

block and a power MOSFET (D-MOS) on single chip.

 One side of load can be grounded to a high-side switch.

 AEC-Q100 qualified.

 Can directly drive a power load from CMOS or TTL logic.

 Built-in protection circuits against over temperature, over current.

 Incorporates a diagnosis function that allows diagnosis output to be read externally at battery short,

load short-circuiting, opening, or over temperature.

 Up to VDD - 40V (Min) of counter electromotive force from an inductance load can be applied.

 Low on-resistance: RDS(ON)=0.12Ω(Max) (@ VDD = 12 V, Tch = 25°C, IO = -2 A)

 WSON10 package for surface mounting that is packed in embossed tape.
