VNN3NV04PTR-E Datasheet/PDFPower Distribution Switches, Load Drivers
The VNN3NV04PTR-E is a high-side switch driver and load switch designed for adaptive power management in applications such as controlling peripherals, computing systems, and telecom equipment. By using this device, system designers can control peripheral power to reduce system iPower demands and maintain system performance.
The integrated high-side switch includes an adjustable current limit, short circuit protection and current monitoring capability. The device consists of two independent channels that can be used individually or in combination to control different loads. The device can be used in multiple applications such as powering up and down peripherals, state machine control for standby current, etc.
Working Principle
The VNN3NV04PTR-E is an IC with two high-side switches that can be used to control the power supplied to a peripheral device. The device has an adjustable current limit and short-circuit protection, making it ideal for controlling the power required by the peripheral device. The device controls the power supply to the peripheral by switching an internal FETs on or off.
The current limit of the device is set by programming the internal registers. This limit prevents any overcurrent or short circuit conditions, protecting both the device and the peripheral. The device also includes current monitoring circuitry that allows system designers to monitor the current drawn by the peripheral device.
The device can be used to power down a peripheral when it is not in use, reducing iPower demands and allowing the system to remain at optimal performance levels. The device also helps to reduce EMI/RFI emissions and to improve audio/video performance.
Application Fields
The VNN3NV04PTR-E is suitable for applications requiring adaptive power management, such as those in computing systems, mobile devices, and communications equipment. The device can be used for powering up and down peripherals, state machine control for standby current, and more.
In addition, the device can be used to reduce EMI/RFI emissions and improve audio/video performance. The device can also be used to reduce overall system iPower demands by cutting power to peripherals when they are not in use.
Conclusion
The VNN3NV04PTR-E is a high-side switch driver and load switch designed for adaptive power management in various applications. The integrated high-side switch includes an adjustable current limit, short circuit protection and current monitoring capability. The device controls the power supply to the peripheral through an FET switch and can be used for powering up and down peripherals, state machine control for standby current, and more. The device also helps to reduce EMI/RFI emissions and to improve audio/video performance.
