Introduction to TPS2814DR
TPS2814DR is a high-performance gate driver IC which offers the user to drive large external MOSFETs and IGBTs. This integrated driver designed for high-speed switching applications supports fast switching speeds and is suited for high-current and high-power applications. It is widely used in power and motor drive applications, such as battery management systems, desktop and server power supplies, motor control, and more.Application Field
The TPS2814DR offers a wide range of applications, including:

• Battery management systems
• Desktop and server power supplies
• Motor control
• Power converters in solar and wind power applications
• Load switching
• DC-DC and AC-DC converter circuits

The TPS2814DR boosts fast-switching performance and can support high current and high power applications. It also provides over-temperature protection and overload protection for secure voltage mode and current mode operation, as well as an integrated ESD protection function. The resourceful characteristics make it ideal for a range of applications across different industries & processes.Working Principle
The TPS2814DR is a wide-range gate driver IC that integrates high-side and low-side outputs, dual supply input, each with standard 5V or 7.5V logic level inputs, which can drive up to 1A into the output MOSFET. The device also features an innovative "Latch Mode" which is activated by an external voltage over threshold on one or both of the control inputs. The latch mode will start switching if only one of the outputs is active and the other still in its previous logic state.The TPS2814DR also includes an integrated short-circuit protection and one open drain output to indicate the pre-charge phase of a power converter. After the pre-charge phase is complete, the fault signal turns off, allowing the power converter to continue to normally operate. This fault signal can also be used to reset the controller if the device is programmed to launch a power cycle after the fault is detected.In addition, the TPS2814DR provides advanced over-temperature protection and overload protection for secure power supply operation in both voltage and current operational modes. With its integrated ESD protection capability and low propagation delay, the device ensures that no temporary interruptions are caused by external electrostatic discharges.Conclusion
The TPS2814DR is an ideal gate driver IC for applications requiring fast switching speeds, high current and power, and over-temperature protection. The device features industry-standard 5V or 7.5V logic level inputs, integrated ESD protection and pre-charge indication, overload protection, and a latch mode feature which makes it ideal for a wide range of power and motor drive applications.
