The UC1709, UC2709, and UC3709 dual high-speed FET drivers are Unitrode products offered by Texas Instruments, designed to efficiently operate power MOSFETs. These devices provide fast switching, with a rise and fall time of 40 ns when driving a 1000 pF load, and feature a high-current source/sink capability up to 1.5 A. They are compatible with 5 V to 40 V operations and maintain a low quiescent current.
Developed utilizing a high-speed Schottky process, the UC3709 family is pin compatible with MMHO026 or DSO026 products, ensuring ease of upgrading without significant circuitry changes. Despite having longer delay times compared to their predecessors, they offer reduced supply current, making them more efficient for contemporary applications.
The datasheet outlines thermal protection as one of the key features of these drivers, safeguarding against overheating and extending their reliability and lifespan.
Absolute Maximum Ratings
For the UC series, the datasheet specifies the absolute maximum ratings, which are the stress limits the driver can handle without incurring permanent damage. Key parameters include:
- Supply Voltage, Vcc: Up to 40 V for all packages
- Output Current, Source or Sink (Steady-State): ±500 mA
- Peak Transient: 1.1 to 1.5 A
- Capacitive Discharge Energy: 15 to 20 mJ
- Digital Inputs: 5.5 V (exceeding this is permissible given current is limited to 10 mA)
- Thermal Resistance Table listed for four different package types (SOIC-16, DIL-16, LCC-16, DIL-16)
Furthermore, it includes the package’s thermal resistance and operating temperature ranges, emphasizing the importance of thermal management in high-speed FET driver applications.
Pin Configuration and Package Details
The datasheet details the pin configurations for various package types, including SOIC-16, DIL-16, LCC-16, and DIL-16, showing users the necessary connections for implementing the driver in a circuit. It specifies “No Internal Connection” (NIC) pins that must be taken into consideration during design.
Texas Instruments highlights that all information, including product specifications and warranties, are up-to-date as of the publication date. They stress that production processing does not automatically entail testing of all parameters.
Ensuring optimal search engine visibility, the summary emphasizes key specifications and features, catering to individuals searching for high-performance, reliable FET drivers suitable for power management applications.
