PMIC - Gate Drivers are essential in energy efficiency, signal integrity and system performance. The TPS2814DG4 is a high-performance gate driver integrated circuit specifically designed for the newest advanced power management ICs. This driver has the capability to provide current up to 14A and supply voltage up to 28V. TPS2814DG4 enables low on resistance and low gate capacitance, as well as high effieicncy and optimized EMI.
The TPS2814DG4 has two different operating modes: high side single rail & two rail. In high side single rail mode, the TPS2814DG4 utilizes one voltage supply and a single output to drive the gate of the power MOSFET. In two-rail mode, two output supplies and two outputs enable the TPS2814DG4 to drive a two-rail gate driving system.
The TPS2814DG4 can drive a wide range of Gatesource and Gate-Sink currents up to 14A and 28V. It can also provide low turn-on and turn-off losses for high efficiency across a wide range of input voltages and frequencies.
The TPS2814DG4 application field is not only limited to high frequency switching power-supply applications, but also extends to low frequency power transfers with high power switching needs. It can also be used in laptop power supplies, LED drivers, battery charging systems, motor drives, and other high power applications.
The working principle behind TPS2814DG4 is to maintain low gate capacitance and gate resistance to ensure optimum power management. High current pulses to both the Gate Source and the Gate Sink are regulated by the TPS2814DG4’s novel power control circuitry. By creating a precise timing reference, the TPS2814DG4 provides a low resistance path for the high current pulses to the power MOSFET gate. The TPS2814DG4 also has flexible gate drive protection built-in including thermal over-current protection and short circuit protection.
In summary, the TPS2814DG4 high performance gate driver is an essential element for high efficiency, signal integrity and system performance. It enables low on resistance and gate capacitance, as well as high efficiency and optimized EMI. It is suitable for a wide range of applications, including laptop power supplies, LED drivers, battery charging systems, motor drives, and other high power applications. Its novel power control circuitry ensures a precise timing reference and provides a low resistance path for the high current pulses to the power MOSFET gate, allowing the TPS2814DG4 to maintain low gate capacitance and gate resistance.
