TPS2811DRG4 is a half-bridge gate driver IC made by Texas Instruments. This IC is ideal for operating and controlling half-bridge logic level power switches in automotive and other applications. The IC features a high-side and low-side driver with pulse/current input mode, disabled PMOS output for bootstrapping operation, and fault detection. TPS2811DRG4 is capable of driving both high-side and low-side N-channel external MOSFETs that are rated from a few milliamps to several amps depending on their specific cores and winding characteristics.

The application field of TPS2811DRG4 includes automotive, digital electronics, and server/storage applications. In automotive applications, TPS2811DRG4 is used in powertrain control systems, electronic stability control systems, instrument clusters, traffic signals, and many other systems. In digital electronics, TPS2811DRG4 is used in point-of-sale machines, medical equipment, industrial control systems, and telecommunications. In server and storage applications, the IC can be used to control 3.3 and 5 V LED lighting, high currents in 1.5 V domains, and as a conductor for various power systems.

The TPS2811DRG4 gate driver is designed to provide fast and reliable switching of high-voltage, high-current power switches. The switch input has a typical high or low level associated with it, and when the switch is triggered the internal gate driver expands the current or voltage of the input with its output devices, allowing the switch to be quickly and accurately actuated. The TPS2811DRG4 is designed to replace the old, slower circuit designs with a faster, efficient and reliable solution.

The TPS2811DRG4 can handle power switches with high currents and high voltages. The gate driver can be used in a range of applications in order to control and quickly switch power switches with higher energies. In addition, parasitic latch-up protection is included to eliminate False OFF switching due to noise disturbing the gate driver. This offers reliable and safe power switch control.

The TPS2811DRG4 has a wide input voltage range from 3.0V to 28V, a usually high switching speed up to 1ms, and a low quiescent current value. By using an external resistor, the slew rate of the output levels can be programmed to suit the application requirement. The TPS2811DRG4 is supplied in a thermally enhanced TSSOP-16 package has an operating temperature range from -40°C to 125°C.

Another great feature of the TPS2811DRG4 is its fault detection features. The IC features a programmable fault monitor which can detect a fault on either the high-side or the low-side drain of the power MOSFET. It also has open drain fault detection on the low-side and open source status on the high-side. In addition, it has a temperature monitor which can detect high local temperatures quickly and accurately.

In conclusion, the TPS2811DRG4 is an excellent choice for gate driver applications due to its high performance, low quiescent current value, wide range of inputs, and fault detection features. The IC is capable of driving N-channel power MOSFETs with a range of currents, is housed in a thermally enhanced TSSOP-16 package, and can operate in a temperature range of -40°C to 125°C. With the TPS2811DRG4, designers can create reliable, high-performance gate driver designs quickly and easily.
