The TPS2811DR integrated circuit, or IC, is a type of power management integrated circuit (PMIC) in the Gate Driver family. It is manufactured by Texas Instruments, and is used to control the gate voltage of low-voltage and high-voltage MOSFETs. It is also known as a low-voltage gate driver, or LVGD. This device is a high-performance, low-power solution for driving power gates with minimal losses.

The TPS2811DR is designed for low-voltage (<2V) and high-voltage (>30V) gate drives across a wide range of applications. This makes it suitable for a variety of applications that require gate drives without significant gate and source series losses, including power management of Electronic Load Switches (ELS), flyback converters, motor drives, and other power gate applications. It is also an excellent choice for FETs operating at low gate-drive energy levels.

The TPS2811DR provides excellent power efficiency and reliability with optimized signal integrity. Its built-in quality assurance features help minimize inrush current and protect against important system threats. Features such as low-current slew rate limiting, negative gate-drive leakage protection, and several other thermal protection measures help ensure system reliability and robustness.

The TPS2811DR’s primary function is to drive MOSFET gates from a low-voltage logic level. The typical gate-drive current of the TPS2811DR is 12mA, with a maximum of 20mA. Its high gate-drive current significantly reduces losses and reduces overall system power consumption. Other features include adjustable turn-on time, adjustable turn-off time, sense pin protection, short-circuit and over-temperature protection, as well as an adjustable fault level.

The TPS2811DR supports a wide range of input and output voltages, making it an ideal choice for a variety of applications.
