The TPS2849PWP is a low-power, adaptive gate drive (AGD) controller offering the flexibility, performance, and scalability needed by most gate driver applications. This device offers the best in class performance, allowing users to easily implement a variety of gate driver designs with significantly lower external components and improved power efficiency. The device offers an excellent integration of MOSFET output drive stages and comprehensive features for comprehensive protection of the gate driver circuitry. The device features a variable overdrive control which allows a wide range of operating parameters and ensures optimal conditions for desired operation under both normal and low temperature conditions. Furthermore, it is adjustable for different polarities and voltages, making it ideal for a wide range of gate driver applications. This article will provide an overview of the application fields, the working principle, and the features of the TPS2849PWP.
Application Fields
The TPS2849PWP is ideally suited for current mode, single-ended and push-pull/bridge convertors, as well as SMPS applications. The device is also well-suited for boosting performance in high-side drivers, and it can be used as an internal gate driver or an external gate driver in high-current applications. It is particularly suitable for floating rail applications and provides a higher voltage range with adjustable over drive control (OVC) protection.
The device is also suitable for variably load line applications and has a maximum frequency rating of 200 MHz, making it the perfect solution for high frequency switching applications. Additionally, the device can be used to reduce overall power consumption, and it is available with a low on-state resistance (RdsD) to reduce switching losses.
Finally, the TPS2849PWP is a highly integrated device, eliminating the need for external components and simplifying the gate drive design.
Working Principle
The TPS2849PWP AGD controller works in several stages. First, the device switches a MOSFET to turn it on, providing the needed gate voltage. Then, the controller adjusts the gate bias voltage to the desired amplitude, providing full MOSFET control while maintaining the desired gate voltage. Finally, the controller can monitor the MOSFET threshold voltage and adjust the gate voltage in order to keep it constant, regardless of temperature or supply voltage variations.
The TPS2849PWP also works in low-dropout (LDO) mode. In this mode, the controller adjusts the output voltage based on the voltage of the power supply, allowing the device to be used in wide input range applications. This ensures that the output voltage is always at the optimal operating voltage for the device, and prevents the power supply from becoming overloaded.
Furthermore, the device features adaptive gate drive (AGD) protection, which prevents catastrophic MOSFET failure due to uncontrolled inductive spikes. This protection is achieved by monitoring the output voltage of the MOSFET and comparing it to a predetermined threshold. If the voltage exceeds the threshold, the controller reduces the gate voltage and prevents the MOSFET from failing. This feature is particularly useful for switching applications, where sudden inductive spikes can overload the power supply and cause device failure.
Features
The TPS2849PWP offers a variety of features that make it an ideal solution for gate driver designs. The device is available with adjustable over-drive control (ODC) protection and variable output voltage to meet the needs of different applications. Additionally, it is configured with integrated current sense protection (IPC) protection, allowing the user to optimize their gate driver design for different conditions.
The device features an adjustable gate voltage setting that range from two to eighteen volts, and is capable of handling voltages as high as twenty-four volts. Additionally, the device is designed with a temperature-compensated gain control, allowing the user to fine-tune the gain for optimal operation in a wide range of temperature conditions.
The TPS2849PWP also features frequency compensation, which prevents the device from becoming unstable when operating at high frequencies. This feature prevents the driver from becoming oscillatory and allows it to provide a clean, stable signal. In addition, the device features a programmable slope compensation, allowing the user to adjust the slope up or down to meet the demands of the application.
Finally, the device is packaged in a small, space-saving PSOP-10 package, allowing the user to reduce board space requirements. Furthermore, the device is compatible with other PSOP-10 devices, which ensures compatibility with existing systems. In summary, the TPS2849PWP is an excellent solution for gate driver designs and offers features that make it ideal for a variety of applications.
