TPS2838PWPR is a highly integrated pulse width modulator (PWM) gate driver with embedded error amplifier, dedicated control, low-noise capacitance multiplier, and current-limit comparator. It belongs to the PMIC - Gate Drivers. It is designed to drive power Mosfets and various insulated gate bipolar transistors (IGBTs) in applications such as power conversion, high power inverters, motor control systems, and protection circuits.

This PWM gate driver easily integrates and monitors power devices with embedded error amplifiers, low-noise capacitance multipliers and current-limit comparators. It provides a regulated voltage source to supply high-power gate drivers and gates. The TPS2838PWPR operates at high frequency, allowing for fast switching speeds and superior power efficiency. The driver\'s low-dropout design ensures clean start-up with minimal current consumption. The PWM output has adjustable switching frequency and cycle-by-cycle current sensing.

The embedded error amplifier accurately controls the output voltage, efficiently monitoring and compensating for external-component variations. The TPS2838PWPR provides an adjustable current limit, utilizing an external current-sense resistor. A unique feature of the TPS2838PWPR is its multiple-level current-limit threshold set-points that help to optimize the current limits and enables the system to be tailored to the specific application.

The TPS2838PWPR also features an adjustable soft-start to control inrush current during power-on and power-off transitions. This protects the whole system from overloading or output voltage spikes. To facilitate fast and reliable gate-charge ramping, the built-in grooving gate-drive section generates a high-voltage high-side gate drive with a low-voltage low-side gate drive for cascade gate-drive applications.

The TPS2838PWPR is also equipped with an under-voltage lockout (UVLO) protection and a thermal shutdown feature to protect the power stage from independently over-voltage, over-current, or over-temperature, ensuring short circuit and thermal overload protection respectively. Furthermore, the device allows the user to quickly change the operating parameters with external pins, providing easily adjustable parameters such as the under voltage lockout and current limit thresholds.

The TPS2838PWPR is an ideal power solution for industrial, consumer, telecom and computer applications and is available in a variety of package options. Highly integrated solutions like the TPS2838PWPR can help reduce the overall system power consumption, improve power efficiency and reliability, and increase the overall cost effectiveness in a wide range of applications.
