The TPS2849PWPR is a high current gate driver IC specially designed to drive Power MOSFETs and IGBTs used in inductive and/or high power applications. This IC is a half bridge gate driver module that operates from 5.0V to 18V and can supply up to 3A peak output current per channel. It provides a precise timing and logic control for PWM applications. The combination of low on-resistance, fast switching times, and low power consumption makes the TPS2849PWPR an ideal choice for high current, high performance systems.

The TPS2849PWPR application field is broad, from telecommunications to industrial drive systems, from powertrain to medical equipment. The module can be used to drive Power MOSFETs and IGBTs operating from low voltage (5V to 18V) to high voltage (up to 500V), up to a maximum continuous current of 1.5A per channel. It is designed for applications requiring precise timing and logic control, and features internal logic circuitry for soft start impulses and shutdown signals when the input supply voltage drops below a certain level.

The working principle of the TPS2849PWPR is simple yet efficient. The module consists of two channels – an input and output – and operates by providing discrete outputs that match the appropriate gate levels required to drive an external MOSFET or IGBT. The module contains two independent channels, each with two high current outputs providing up to 3A of peak output current per channel. The device is protected against over-voltage and over-current by integrated protection and diagnostic circuits. Additionally, the device includes a thermal protection circuit and a high side floating-gate protection circuit.

The main features of the TPS2849PWPR are low switching times, high current-compatibility and integrated logic control for precise timing and logic control in PWM applications. The module features an adjustable dead time to prevent high current shoot-through, as well as advanced short circuit protection for safe operation. Furthermore, the device features variable dead time for modulated switching and adjustable on-times, with a maximum on-time of 250µs. In addition, the device provides over-voltage protection, over-current protection, an active-low enable signal and low standby power.

In conclusion, the TPS2849PWPR is a versatile gate driver IC that can be used to drive Power MOSFETs and IGBTs in wide range of applications. It offers excellent performance, low on-resistance, fast switching times, variable dead time and adjustable on-times for precise timing and logic control. Additionally, the device features a number of integrated protection and diagnostic circuits for safe operation.
