The TD62207BFG is a high-voltage source driver manufactured by Toshiba Semiconductor and Storage. It is designed to provide a controlled source of current to various loads. Unlike the TD6210x series which are Darlington sink drivers, the TD62207BFG sources current, making it suitable for applications like driving LEDs, VFDs and other loads requiring a positive voltage source.

Applications

• LED displays (especially common anode configurations)
• Vacuum Fluorescent Displays (VFD)
• Level shifting
• Driving other loads requiring a controlled current source

Features

• 8-channel source driver
• High output voltage (consult datasheet for specific voltage rating, typically up to 80V)
• Output current (consult datasheet for specific current sourcing capability per channel, typically in the milliamps)
• TTL and CMOS compatible inputs
• Built-in shift register for serial data input
• Output enable function
• Surface mount package (SSOP or similar)

Benefits

• Simplified interface to high voltage loads
• Reduced component count due to integrated design
• Compact design due to surface mount packaging
• Easy control through serial data input
• Flexible output control with the output enable function

Additional Details

The TD62207BFG features a shift register to serially input data, reducing the number of required control lines from a microcontroller or other control logic. The output enable pin provides a global on/off control for all outputs. Datasheet specifications should be consulted for exact voltage and current limitations. Proper heat management techniques may be needed depending on the application's load and environmental conditions. External current limiting resistors may also be beneficial depending on the load being driven. The "G" suffix typically indicates a lead-free or green compliant version.
