Introduction
The VNQ5160K-E is an integrated power management integrated circuit from STMicroelectronics that is designed for portable devices. It is a versatile ultra-low power, single-chip PMIC for stable and efficient power supply management, switching and load balancing of the system. It combines N-channel MOSFETs output drivers, load drivers, DC-DC voltage regulators, charge pumps, and power sequencing into a compact package. This PMIC is ideally suited for use in the latest smartphones, tablets, and other handheld gadgets. Application Field
The VNQ5160K-E is designed for use in applications that require a low power, single-chip PMIC for power management. It is particularly well-suited for use in applications with a monitored battery, such as a Bluetooth mouse or a smartphone, where the system must be able to switch the power supplies on and off. It can also be used for applications which require a device wide power switch, such as a digital camera that needs to switch between a main power supply and a battery when the battery is depleted. It can also be used for a variety of power management applications, such as controlling power sequencing in a laptop computer. It supports up to 10 power supplies, so it is suitable for applications with multiple power sources.Working Principle
The VNQ5160K-E integrates a variety of components into a single package. It includes N-channel MOSFET output drivers, load drivers, and DC-DC voltage regulators. The N-channel MOSFETs provide the required power control by enabling or disabling the necessary power supplies. The load drivers are used to switch the loads, such as LED displays, on and off, and the DC-DC voltage regulator can be used to step down the input voltage for power management applications. The VNQ5160K-E also includes a power sequencing controller, which can be used to control the power-on sequence of all the supplies, allowing for safe and efficient start-up of the system. By melting all these components into the same package, the VNQ5160K-E PMIC allows for a more compact, efficient, and cost-effective solution for power supply management. Conclusion
The VNQ5160K-E is an integrated power management integrated circuit from STMicroelectronics that is designed for portable devices. It is a versatile ultra-low power, single-chip PMIC with N-channel MOSFET output drivers, load drivers, and DC-DC voltage regulators integrated. It is suitable for applications with a monitored battery, such as a Bluetooth mouse, or a device wide power switch, such as a digital camera. It can also be used to control power sequencing in a laptop computer. The VNQ5160K-E’s compact package and efficient components make it an ideal choice for power supply management.
