PMIC - Gate Drivers

UCC27517ADBVR is a highly integrated, 11-channel Gate Driver IC with a high-voltage high-current output stage that is designed to drive Power MOSFETs and IGBTs. It offers low power consumption, up to 12-16 pins in a single footprint size and an input voltage range of 3V to 15V. It is also equipped with integrated safety features, such as a latch-off protection, under-voltage/over-voltage protection, soft-start and diagnostics functions.

This Gate Driver is mainly used in motor controlling applications, such as motor control cabinets and motor drives, among others. It also finds applications in industrial and professional power control, and renewable energy driven applications. Its ability to drive large loads with a minimum of power consumption makes it suitable for a wide range of power management tasks.

Working Principle

The working principle of the UCC27517ADBVR Gate Driver is based on the fact that the gate voltage of a power transistor (MOSFET or IGBT) is directly proportional to the voltage applied to its gate. Essentially, the driver receives a low-power input signal, such as one from a microcontroller, and then amplifies this signal to provide a higher gate voltage to the power transistor. The result is that more current is allowed to flow through the power transistor, enabling it to turn on more quickly and achieve higher switching speeds and better efficiency.

The UCC27517ADBVR features an integrated high-current and high-voltage power stage output that can drive up to 11 channels simultaneously. It is also equipped with over-voltage and under-voltage protection, latch-off protection, soft-start, and diagnostics functions to ensure safety and provide an excellent performance. Additionally, it is designed to operate over an input voltage range of 3V to 15V.
