PMIC, or Power Management Integrated Circuit, is the technological answer to managing power flow in varying devices and applications. The VND920-E is a PMIC from STMicroelectronics which applies to a vast range of applications.

The VND920-E is a MOSFET switch integrated circuit, or PMIC for short. With two driving channels with controlled rise and fall times, it allows for simultaneous driving of two devices. It is built on an advanced 90V process, which allows for higher temperatures and an enhanced robustness. The integrated circuit also features an advanced input clamp circuit which limits the power supply current and prevents other connected circuits from overvoltage.

The VND920-E presents a wide range of applications, including loading and unloading functions, LED drivers, motor drivers and other short-circuit-proof situations. It is primarily used to set up a controlled energizing/de-energizing of the load in order to limit the current. It is also used to avoid switching transients that can be produced when loads are turned on and off. It can be used in various controllers, switches and relays to control their switching states.

The operating principle of the VND920-E is quite simple. It uses field effect transistors as its main switching elements, which are sensitive to an applied gate voltage. The gate is connected to two open-collector N-channel MOSFET\'s (NMOS). The MOSFET sources and gates are connected together, which allows its gate voltage to be controlled independently. The combination of the MOSFETs and gate voltage control makes the VND920-E an efficient power distribution device with low power consumption.

When the VND920-E is triggered, the MOSFETs close their gates and the power is distributed to the connected circuits. The output is then regulated and limited to the desired current levels. This ensures safer, faster and more reliable power transfer. Additionally, the parasitic capacitances of the MOSFETs and gate resistors also help to protect the circuit from overvoltages.

Thanks to its wide range of applications, low power consumption and high efficiency, the VND920-E is becoming increasingly popular in various fields. It is most commonly used in household appliances, automotive systems, industrial machines and consumer electronics. With its versatile features, the VND920-E is a crucial component for many power management systems.
