The VN808-32-E is an integrated power management IC (PMIC) designed to facilitate the proper voltage levels and power distribution between various circuits in devices like cellphones and tablets, as well as other applications. It incorporates a high-side, low-side, and load driver to switch, monitor, and protect power signals. This PMIC can be used in a variety of applications and is designed to provide both high-current load drive, switched power regulation, and exceptional overload protection.

Features

The VN808-32-E PMIC includes a high-side switch, a low-side switch, and a load driver for maximum flexibility and optimization for the power distribution requirements of the application. It switches high-current rails and supplies up to 1 amp of load drive current, allowing for small and low power applications where space saving is critical. It also features an internal current limit that protects against damaging and damaging overload conditions. This PMIC can also be configured as an open-drain MOSFET driver or half bridge and has adjustable current, output voltage, and current limit protection.

Working Principle

The VN808-32-E PMIC utilizes a core technology based on the “H-bridge”, which means the high-side and low-side switches are operated separately. This allows for better power control and efficient power distribution. The main device is the MOSFET, which acts as a switching element. The MOSFET has a gate-source threshold voltage, which controls the switch. Additional features like adjustability, temperature monitoring and current protections are implemented through external components.

Applications

The VN808-32-E PMIC is used widely in embedded systems, smartphones, and other portable devices to switch and regulate power levels. This PMIC can be found in consumer products such as portable music players, digital cameras, Bluetooth, and other small mobile devices. It is also widely used in appliance applications such as air conditioners, heaters, vacuum cleaners, and home automation. Additionally, this PMIC can also be found in industrial and medical applications.

Conclusion

The VN808-32-E PMIC is an ideal solution for power distribution, load drive, and overload protection. It is a versatile, reliable, and cost-effective PMIC that is optimal for consumer, industrial, and medical applications. The integrated voltage level and current protection features provide the needed safety in case of over-voltage or over-current conditions.
