The UCC27524DSDR is an integrated circuit (IC) component manufactured by Texas Instruments. It is a dual high-speed, low-side gate driver designed for driving MOSFETs and IGBTs in various power electronics applications. This IC provides excellent switching performance while minimizing power dissipation and reducing electromagnetic interference.
One of the key features of the UCC27524DSDR is its ability to operate from a wide range of supply voltages, from 4.5V to 18V, making it suitable for a variety of power supply configurations. It can deliver a peak output current of up to 4A, enabling it to drive power devices with low gate capacitance quickly.
To ensure robust and reliable operation, this gate driver incorporates several protection features. It has an undervoltage lockout function that prevents the MOSFET or IGBT from operating at insufficient voltage levels. Additionally, it incorporates a shoot-through protection circuit that avoids simultaneous conduction of both high-side and low-side MOSFETs or IGBTs, preventing damage to the power devices.
The UCC27524DSDR also offers a unique adaptive dead-time control mechanism, which adjusts the dead time between the high-side and low-side signals based on the switch node voltage. This feature helps optimize efficiency and minimize power losses during operation.
Furthermore, this IC component is designed to withstand high electromagnetic interference (EMI) environments
