The UCC27526DSDR is a high-speed, dual-channel, low-side gate driver device designed by Texas Instruments to deliver robust and efficient performance in driving power MOSFETs and IGBTs. This gate driver is particularly suitable for high-frequency power conversion applications that require efficient switching, such as in switch-mode power supplies, motor controllers, inverters, and DC-DC converters.

Key Features

• Output Drive Strength: The UCC27526DSDR offers a strong drive strength of 4A source and 4A sink current capability, ensuring fast and reliable switching of connected power devices.
• Independent Inputs: With two independent input channels, it allows for flexible control schemes, including the ability to drive two separate MOSFETs or IGBTs or to control both the high-side and low-side switches in a half-bridge configuration.
• Wide Supply Voltage Range: It operates over a wide supply voltage range from 4.5V to 18V, making it compatible with a variety of control logic levels and providing design flexibility.
• High-Speed Operation: The device is capable of high-speed operation with propagation delays as low as 13ns, ensuring minimal delay between the control input signal and the power device switching, which is critical for high-frequency applications.
• Robust Output Drive: The UCC27526DSDR features robust output drive stages with pull-up and pull-down resistance to help protect against Miller-induced parasitic turn-on.
• Industry-Standard Package: The device is available in an industry-standard SOIC-8 package, which is widely accepted and provides a compact footprint for space-constrained applications.
