The UA9667PC is a high-current, high-voltage peripheral driver manufactured by Fairchild/ON Semiconductor. It's designed to interface between low-level logic circuits and high-power loads, such as relays, solenoids, lamps, and other electromechanical devices. The 'PC' suffix typically indicates the package type, likely a plastic DIP (Dual In-Line Package).

Applications

• Relay drivers
• Solenoid drivers
• Lamp drivers
• Stepper motor drivers
• Line drivers
• Logic buffers

Features

• High output current (e.g., up to 500mA or higher)
• High output voltage (e.g., up to 80V or higher)
• TTL/CMOS compatible inputs
• Internal clamp diodes for inductive load protection
• High-speed switching
• Single supply operation
• Plastic DIP package (PC)

Benefits

• High current and voltage capability: Drives a wide range of high-power loads.
• TTL/CMOS compatibility: Interfaces directly with common logic circuits.
• Inductive load protection: Protects the driver from damage caused by inductive kickback.
• High-speed switching: Enables fast response times.
• Easy to use: Requires minimal external components.
• Cost-effective: Provides a simple and efficient solution for driving high-power loads.

Additional Details

The UA9667PC is a monolithic integrated circuit that provides a high-current, high-voltage output. The internal clamp diodes protect the driver from voltage spikes caused by inductive loads. The TTL/CMOS compatible inputs allow the driver to be directly controlled by logic circuits. The high-speed switching capability enables the driver to be used in applications requiring fast response times. The single supply operation simplifies power supply design. The device typically requires a bypass capacitor to ensure stable operation. Refer to the datasheet for detailed specifications, application notes, and safety considerations. The specific current and voltage ratings, as well as the switching speed, will vary depending on the exact model number within the UA9667 series. Proper heat sinking may be required for high-current applications.
