Toshiba Intelligent Power Device Silicon Monolithic Power MOS Integrated circuit
TPD1038F
Motor, Solenoid, Lamp Drivers
High Side Power Switch
TPD1038F is a monolithic power IC for high-side switches. The
IC has a vertical MOS FET output which can be directly driven
from a CMOS or TTL logic circuit (eg, an MPU). The device offers
intelligent self-protection and diagnostic functions.
Features
· A monolithic power IC with a structure combining a control
block (Bi-CMOS) and a vertical power MOS FET 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 overheating and load short
circuiting.
· Incorporates a diagnosis function that allows diagnosis output to be read externally at load short-circuiting,
opening, or overheating.
· Up to -(50-V
DD
) -(60-V
DD
) of counterelectromotive force from an L load can be applied.
· Low on Resistance : R
DS(ON)
=120m(max) ( @ V
DD
= 12 VTa = 25Io = 2 A)
· 8-pin SOP package for surface mounting can be packed in tape.
Pin Assignment Marking
That because of its MOS structure, this product is sensitive to static electrocity.

Function
1 OUT
Output pin. When the load is short circuited and current in excessof the detection current (3A min)
flows to the output pin , the output automatically turns on or off.
2 GND
Ground
pin.
3 DIAG
Self-diagnosis detection pin.Goes low when overheating is detected or when output is short circuit
with input on (high). N-channel open drain.
4 IN
Input pin. Input is CMOS compatible, with pull down resistor connected. Even if the input is open,
output will not accidentally turn on.
