VND920PTR-E Application Field and Working Principle

The VND920PTR-E is popularly used in the power management and power distribution industry. This high-performance power switch is manufactured by Infineon technologies, a leading German semiconductor company. The single die integrated circuit (IC) combines motor voltage control, low RDSon and ultra-low output resistance to offer exceptional current and voltage stability.

Application Field

The VND920PTR-E is the ideal choice for power distribution applications. It is used in automotive and lighting systems, automotive body electronics, home appliances, and general industrial electronics applications. The power switch is also used in radio frequency (RF) applications including mobile phones and broadband communication devices.

The VND920PTR-E is a high-performance single-channel load driver, designed for automotive applications. The device is designed to drive and control single-channel PWM solenoids to achieve low RDSon and high switching performance. It offers a low quiescent current, low output resistance and high power capability up to 100W.

The device is designed using advanced CMOS process and provides ultra-fast switching times and high current-carrying capability. It can operate at high frequencies up to 2MHz, with excellent thermal and voltage performance.

Working Principle

The VND920PTR-E is an intelligent, off-line high-side switch. The device features an integrated driver circuit and its output transistor controlled digitally. The device provides fast turn-on and turn-off time of 5 ns, low output resistance of 7.5 mΩ and high efficiency of up to 95%.

When the device is in the off-state, the voltage at the output is zero and the load is disconnected from the supply. When the control input is high (>2V), the device activates, providing a high level of power delivery. When the control input is low (< 0.8V), the device into the off-state, disconnecting the load from the supply. The VND920PTR-E features a built-in current limit circuit, making it ideal for driving loads with high capacitive loads. It also features built-in thermal protection and reverse battery protection.

Conclusion

In conclusion, the VND920PTR-E is a powerful single-channel power switch designed for high-frequency applications. It is designed using advanced CMOS technology, providing fast switching times and high current-carrying capability. The device is ideal for power distribution applications, including automotive and lighting systems, automotive body electronics, home appliances, and general industrial electronics applications.
