TC4428VOA713 application field and working principle

PMIC - Gate Drivers are a type of integrated circuits used to control switches and power MOSFETs (Metal Oxide Semiconductor Field-Effect Transistors). The TC4428VOA713 is an example of a PMIC - Gate Driver specifically designed for high-side and low-side power MOSFETs. A key advantage of the TC4428VOA713 is its ability to drive high-voltage loads, which can reach up to 60 V and beyond. In addition, the TC4428VOA713 is capable of operating at high speeds, up to 700 kHz, as well as low power consumption, which is essential for driving portable applications. These features make this PMIC - Gate Driver suitable for a wide range of applications including battery powered devices, automotive ECUs (electronic control units), white goods and house appliances, and industrial equipment.

Working Principle of the TC4428VOA713

When electricity is supplied to the TC4428VOA713, the PMIC - Gate Driver is put into an active state where it supplies power to the MOSFETs when it is instructed to do so. This happens by the PMIC - Gate Driver receiving an input signal from a controller such as a microcontroller unit (MCU). The MCU commands the TC4428VOA713 to enable or disable the MOSFETs, which the PMIC - Gate Driver is then responsible for executing.The TC4428VOA713 then triggers a series of events that enable the MOSFETs to switch on. This occurs when the PMIC - Gate Driver supplies a voltage to the gate of the MOSFET, which increases the internal conductivity and therefore allows a current to flow through the load. This process is known as ‘ gate turn-on’. Once the gate is triggered, the PMIC - Gate Driver is then responsible for ensuring a safe controlled operation of the MOSFETs by monitoring the voltage levels at the source, the gate, and the drain. It does this by using two sets of integrated voltage clamps, which prevents any over-voltages or undershoot voltages from potentially damaging the MOSFETs. In addition to monitoring the MOSFETs, the TC4428VOA713 also offers solid protection against shorts, open loads, and reverse battery conditions. This helps to ensure the performance and reliability of the overall system, and keeps the MOSFETs safe from damage in the long term. Once the turn-on process has been completed, the TC4428VOA713 will then monitor the voltage levels. If they are outside of the range that the MOSFETs can safely operate at then the PMIC - Gate Driver will switch them off. This is known as ‘gate turn-off’. Once the MOSFETs have been switched off, the PMIC - Gate Driver will then enter a sleep state until the MCU sends an input signal to it, at which point the TC4428VOA713 will again bring the MOSFETs into an active state.

Conclusion

The TC4428VOA713 is a PMIC - Gate Driver designed for high-voltage, high-speed, and low-power applications. It is capable of driving high-side and low-side power MOSFETs, allowing it to be used in a variety of applications including automotive systems and industrial equipment.The TC4428VOA713 is able to do this by receiving input signals from an MCU and controlling the voltage levels of the MOSFETs to ensure a safe operation. In addition, the PMIC - Gate Driver also offers protection against a variety of conditions including over-voltage, shorts, open loads and reverse battery conditions.Overall, this makes the TC4428VOA713 an ideal choice for a variety of applications requiring a reliable and efficient PMIC - Gate Driver.
