The TD62783AFG is a high-voltage, high-current sink driver array manufactured by Toshiba Semiconductor and Storage. The 'G' suffix commonly denotes a lead-free or halogen-free version, compliant with environmental regulations. It interfaces between low-level logic signals and higher-power loads in applications requiring a sinking configuration.

Applications

• Driving relays (sinking configuration)
• Driving solenoids (sinking configuration)
• Driving stepper motors (sinking configuration)
• Driving LED displays (common anode configuration)
• Driving small DC motors (sinking configuration)

Features

• High output voltage: 50V (minimum)
• High output current: 350mA (maximum) per channel
• 8 independent channels
• TTL and 5V CMOS logic compatible inputs
• Integrated clamp diodes for inductive load protection
• Package: SOP-18 (Small Outline Package)

Benefits

• Simplifies interfacing between low-power logic and high-power loads requiring a sinking configuration.
• Protects the driver from voltage spikes when switching inductive loads, ensuring reliability.
• Reduces component count and simplifies circuit design.
• Provides versatile control with eight independent channels.
• Offers compatibility with various logic levels.
• Environmentally friendly due to lead-free/halogen-free construction.

Additional Details

The TD62783AFG incorporates internal clamp diodes to handle inductive kickback, which is crucial when driving inductive loads like relays and solenoids. The inputs are designed for compatibility with both TTL and 5V CMOS logic levels. The SOP-18 package enables surface mounting. Consult the datasheet for complete electrical characteristics, timing parameters, thermal specifications, and environmental compliance details. The 'G' suffix signifies compliance with environmental regulations such as RoHS (Restriction of Hazardous Substances). Operating temperature range typically spans from -40°C to +85°C. It is a sink driver; it connects the load to ground when active.
