.TPS28225D Application Field and Working PrincipleThe TPS28225D is a gate driving integrated circuit (IC) from Texas Instruments that combines power management and signal conditioning for low-frequency and high-frequency applications. The device is used for gate driving in automotive, consumer, and industrial applications.The main features of the TPS28225D are: •Operating voltage of 6 to 18 V•Operating temperature of -40 °C to 125 °C•Internal MOSFET clamps on the outputs•High ESD tolerance (1.5 kV HBM)•Open/short load protection•Active Miller ClampsThe TPS28225D is a two-channel gate driver that provides high drive current for powering N-type MOSFETs or IGBTs (Insulated Gate Bipolar Transistors). The device has two half-bridge or full-bridge outputs that can switch at high-frequency (up to 500 kHz). It is capable of driving up to 4 A peak and 1.8 A RMS per channel. It also has an adjustable looped rise and fall time to protect the output transistors from damaging dV/dt and dI/dt transients.The TPS28225D also has an adjustable protection circuit that monitors the voltages and current of the output and provides protection against overcurrent and overvoltage conditions. In the event of an overcurrent or overvoltage condition, the protection circuit will turn off the output and activate the open/short load protection circuit. This circuit will then pull the outputs to a safe level and activate a Fault flag if the fault persists.The TPS28225D also has a number of ESD protection features that protect the device from electrostatic discharge. These features include ESD protection diodes on each output, as well as active and passive Miller Clamps on each output to safely guide ESD current away from the device.The TPS28225D is a great choice for automotive, consumer, and industrial applications due to its it\'s high drive current and ESD protection features. It is also easy to use and configure, making it an ideal solution for a wide range of applications.
