The UCC27424DGN is an integrated circuit (IC) component designed for high-speed, dual-channel power MOSFET drivers. It is manufactured by Texas Instruments and offers a range of features that make it suitable for various applications.
One of the key features of the UCC27424DGN is its ability to drive large MOSFETs efficiently. It provides high peak-current drive capability (up to 4 A) while maintaining fast rise and fall times, which allows for efficient and effective switching of power MOSFETs. This makes it ideal for applications that require high power switching, such as motor drives, uninterruptible power supplies (UPS), and power converters.
The UCC27424DGN operates over a wide supply voltage range, from 4.5 V to 14 V. This wide range makes it compatible with a variety of power supply designs and allows for flexibility in system configurations. It also incorporates an under-voltage lockout (UVLO) feature that ensures proper operation of the driver when the supply voltage falls below a certain threshold.
To enhance system reliability and protection, the UCC27424DGN offers several integrated protection features. It includes shoot-through protection, which prevents simultaneous conduction of the high-side and low-side MOSFETs, thus avoiding destructive current spikes. Additionally, it has built-in thermal shutdown protection that disables the driver if it exceeds a safe operating temperature range, protecting the IC from thermal damage
