TOSHIBA Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit
TPD1024AS
Low-Side Power Switch for Motors, Solenoids, and Lamp Drivers
TPD1024AS is a monolithic power IC for low-side switches. The IC has a
vertical MOS FET output which can be directly driven from a CMOS or
TTL logic circuit(e.g, an MPU). The device offers intelligent selfprotection
function.
Features
A monolithic power IC with a new structure combining a control block
and a vertical power MOS FET(-MOS) on a single chip.
Can directly drive a power load from a CMOS logic.
Built-in protection against overvoltage, load short circuiting, and
thermal shutdown.

pin.
2 OUT
Output pin.
When current in excess of the typical current (3.5 A (typ.)) flows to the output pin, the current limiter
operates to protect the IC.
3 IN
Input pin.
Input is CMOS-compatible, with pull-down resistor connected. Even if the input is open, output will not
accidentally turn on.
