TPD1033F TOSHIBA Intelligent Power Device Silicon Monolithic Power MOS Integrated Circuit 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 short-circuiting. Weight: 0.08 g (typ.) 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 : RON = 220 mΩ (max) z Low operating current : IDD = 1 mA (typ.), (@VDD = 12 V, VIN = 0 V) z 8-pin SOP package for surface mounting can be packed in tape.

(top view) Note: Due to its MOS structure, this product is sensitive to static electricity. 1 2006-10-31 TPD1033F Block Diagram Pin Description Pin No. Symbol Function 1 IN 2 DIAG Self-diagnosis detection pin. Goes low when overheating is detected or when output is short-circuited with input on (high). n-channel open drain. 3 GND Ground pin. 4 VDD Power pin. 5, 6, 7 OUT Output pin. When the load is short-circuited and current in excess of the detection current (8 A typ.) flows to the output pin, the output automatically turns on or off. Input pin. Input is CMOS-compatible, with pull-down resistor connected. Even if the input is open, output will not accidentally turn on. 2 2006-10-31 TPD1033F Timing Chart Truth Table Input Signal Output Signal Diagnosis Output H H H L L L H L L L L L H H H L H H H L L L L L 3 State Normal Load short-circuited Load open Overtemperature 2006-10-31 TPD1033F Absolute Maximum Ratings (Ta = 25°C) Characteristic Symbol Rating Unite VDS 60 V DC VDD (1) 25 V Pulse VDD (2) 60 (Rs = 1Ω,τ= 250 ms) V Drain-source voltage Supply voltage DC VIN (1) -0.5 ~ 12 V Pulse VIN (2) VDD (1) + 1.5 (t = 100 ms) V VDIAG -0.5 ~ 25 V Output current IO Internally limited A Input current IIN ± 10 mA IDIAG 5 mA Input voltage Diagnosis output voltage Diagnosis output current 1.4 Note 1 2.4 Note 2 W Power dissipation (Ta = 25°C) PD Operating temperature Topr - 40 ~ 110 °C Channel temperature Tch 150 °C Storage temperature Tstg - 55 ~ 150 °C Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges.
