Introducing the UCC27211DR High-Side and Low-Side Driver from Texas Instruments
The UCC27211DR is a state-of-the-art, high-frequency MOSFET driver designed to drive both the high-side and low-side power N-Channel MOSFETs in a synchronous buck or a half-bridge configuration. Manufactured by Texas Instruments, this driver is a part of their UCC27211 series, tailored for a wide range of applications such as motor control, DC-DC converters, and power supply systems.
With an industry-leading 4-A peak source and 4-A sink current capability, the UCC27211DR ensures robust drive strength and fast switching performance for high power applications. This driver is particularly notable for its wide supply voltage range of 10 to 20V, making it versatile for various system designs.
One of the key features of the UCC27211DR is its high-side bootstrap diode. This integrated diode simplifies the PCB layout and reduces external component count, which not only saves space but also reduces system cost and complexity. The device also offers a high drive voltage of up to 120V, which provides a significant margin for high-voltage applications, ensuring reliability and longevity of the system.
Furthermore, the UCC27211DR boasts a robust 3.3V and 5V logic compatible input, which allows for seamless integration with modern microcontrollers and DSPs. This compatibility ensures that the driver can be easily controlled and interfaced with in a wide range of electronic systems.
For protection, the UCC27211DR incorporates under-voltage lockout (UVLO) for both high-side and low-side, ensuring that the MOSFETs are operated at safe voltage levels. This feature protects both the driver and the power MOSFETs from damage due to insufficient gate voltage.
The device is offered in a compact 8-pin SOIC package, designated by the "DR" suffix in its part number, which is ideal for space-constrained applications. The UCC27211DR is also specified over an extended temperature range of -40°C to 140°C, ensuring performance in extreme conditions.
Overall, the UCC27211DR from Texas Instruments represents a robust and efficient solution for driving high-side and low-side power MOSFETs, offering designers a high-performance driver with integrated features that simplify design and enhance system reliability.
