The TD62309FG is a high-voltage, high-current source driver manufactured by Toshiba Semiconductor and Storage. It's designed to drive inductive loads such as relays, solenoids, and stepping motors in various applications. This device features built-in clamping diodes to protect the outputs from voltage surges when driving inductive loads.

Applications

• Relay drivers
• Solenoid drivers
• Stepping motor drivers
• Logic buffers
• Lamp drivers
• LED drivers

Features

• High output voltage: 50V
• High output current: 500mA (single output)
• Built-in clamping diodes
• Input compatible with TTL and 5V CMOS logic
• Low saturation voltage
• Available in a small outline package (SOP)

Benefits

• Provides a robust and reliable interface between low-voltage logic circuits and high-voltage/high-current loads.
• Simplified circuit design due to integrated clamping diodes.
• Reduces the number of external components, saving board space and cost.
• Ensures reliable operation even in harsh environments.

Additional Details

The TD62309FG consists of seven independent sourcing drivers. Each driver features an input pin, an output pin, and a clamping diode connected between the output and the supply voltage. The clamping diodes provide protection against inductive kickback, which can damage the device. The device is designed for easy interfacing with TTL and 5V CMOS logic circuits. The low saturation voltage of the output transistors ensures efficient operation and reduces power dissipation. The TD62309FG is available in a SOP-16 package. The operating temperature range is -40°C to +85°C.
