Integrated Circuit. TPD1052F Datasheet
Toshiba Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit
High-side Power Switch for Motor, Solenoid and Lamp Drivers
The TPD1052F is a monolithic power IC intended for high-side load
switching applications. The input can be directly driven from CMOS or
TTL logic (e.g., an MPU). The TPD1052F provides intelligent protection
and diagnostic functions.
z A structure that incorporates Bi-CMOS control circuitry and a power
MOSFET (DMOS) on a single chip.
z One side of the load can be grounded.
z Can be directly driven from a microprocessor.
z Overtemperature and load short-circuit (Overcurrent) protections are
Weight: 0.017g (typ.)
z Incorporates a diagnosis function that allows diagnosis output to be read externally at load short (Overcurrent),
z Low ON- resistance. : RDS(ON) = 0.8Ω (Max) @VDD = 12V, IO = 0.5A, Tch=25℃
z Low supply current. : IDD = 10μA (Max), @VDD = 12V, VIN = 0V, Tch=25℃
z Housed in the PS-8 package and supplied in embossed carrier tape.

Power supply pin.
Input pin. The IN pin has an internal pull-down resistor.
Even if the IN pin is open, the output will not accidentally turn on.
Overcurrent detection/protection is IOC(clamp) in the Mask time.
If the capacitor and the resistance is not connected to MASK pin, overcurrent protection is IOC(duty).
Self-diagnosis detection pin. npn open collector.
When Input is “H”(Output on), and Overcurrent or Overtemperature is detected, DIAG becomes low
level and it is latched.
When input is low level, the state of latch is reseted.
Output pin. When a load short-circuit causes an overcurrent (0.8A Min) to flow into a device, output
current is limited in order to protect the IC.
