VN808CM-E is a programmable and protected power distribution switch, load driver, boost regulator power management integrated circuit(PMIC). It is designed for the GHz to sub GHz wireless applications. The features of the device include current-limit and reverse current protection, temperature monitoring and blinking output current, maximum operating voltages of up to 24 V, and pulse width modulation (PWM) modulation with programmable frequency up to 20MHz.

The VN808CM-E contains two power distribution switches, two load drivers and two boost regulators. The power distribution switches enable and disable the power to components connected to the device. The load drivers are used to drive N-Channel MOSFET switches, and the boost regulator provides power to a component when the input supply is lower than the component’s operating voltage. The device also features current-limit and reverse current protection, temperature monitoring, and an integrated blinking output current peak detector.

The VN808CM-E is ideal for use in a variety of GHz to sub GHz wireless applications such as Bluetooth + Wi-Fi, ZigBee and LoRa, to name a few. The device features programmable switching and load driven parameters which can be used to reduce power consumption and improve system efficiency. It also features a low on-resistance of 4.8 mΩ, enabling power savings and improved power transfer efficiency. The integrated temperature monitor and blinking output current also provide more information about the system’s operation, improving system protection and reliability.

The VN808CM-E is powered by a 3.3 Volt power source with an operating range of 1.8V to 5V. The boost regulator is adjustable and can provide a maximum output voltage of 24V. The device also includes two power good pins that can be monitored to determine if the circuit is properly regulated.

The working principle of the VN808CM-E is as follows. The device is powered from a 3.3V supply and the power is distributed to components connected to the device via the power distribution switches. The integrated boost regulator then provides power to the component when the input supply is lower than the component’s operating voltage. The load drivers are used to drive the N-Channel MOSFET switches and the device contains current-limit and reverse current protection, temperature monitoring and blinking output current peak detectors. The device can be programmed to meet the needs of a variety of GHz to sub GHz wireless applications.

In conclusion, the VN808CM-E is a programmable and protected power management integrated circuit designed for the GHz to sub GHz wireless applications. It contains two power distribution switches, two load drivers, and two boost regulators. The device features current-limit and reverse current protection, temperature monitoring and blinking output current peak detection, and programmable switching and load driven parameters enabling reduced power consumption and improved system efficiency. The device is powered from a 3.3V supply, has an operating range of 1.8V to 5V, and the boost regulator can provide a maximum output voltage of up to 24V.
