The TD62002AFG is a high-voltage, high-current Darlington transistor array manufactured by Toshiba Semiconductor and Storage. It is designed for driving inductive loads such as relays, solenoids, and lamps. The device consists of seven NPN Darlington pairs, each capable of handling up to 500mA of output current and 50V of output voltage. The TD62002AFG features integrated suppression diodes for each Darlington pair to protect against back EMF generated when switching inductive loads. This device also incorporates input resistors, simplifying the interface with microcontrollers and logic circuits.

Applications

• Driving relays and solenoids
• Driving stepper motors
• Driving LED displays
• Driving incandescent lamps
• Logic Buffers
• Line drivers

Features

• Seven Darlington pairs in a single package
• High output voltage (50V)
• High output current (500mA per channel)
• Integrated suppression diodes for inductive load protection
• Input resistors for simplified interfacing
• Available in a small SSOP16 package

Benefits

• Simplified circuit design: The integrated Darlington array reduces component count and simplifies board layout.
• High current driving capability: Each channel can drive relatively high current loads directly.
• Protection against inductive kickback: The built-in suppression diodes protect the circuit from damage caused by inductive loads.
• Logic compatibility: The input pins are compatible with a wide range of logic levels.
• Compact size: The SSOP16 package allows for high-density board layouts.

Additional Details

The TD62002AFG operates over a wide temperature range. It's typically used in applications where multiple loads need to be controlled from a digital circuit. The input resistors allow direct interfacing with microcontrollers and other digital logic devices without the need for external resistors. The device is commonly used in industrial control systems, consumer electronics, and automotive applications where space is limited. The small SSOP package makes it ideal for compact designs.
