Power Management Integrated Circuit (PMIC) play important roles in the operation of electronic devices due to its functionality as a switch, driver, and measurement devices. It also contains other components such as voltage regulators, digital power supply, and programmable logic. VN808CM-32-E is a PMIC device widely used in many applications.

VN808CM-32-E is a Power Distribution Switches, Load Drivers that integrates gate drivers, low side drivers and control logic. It has a wide operating voltage range from 8V to 32V, making it suitable for driving AC/DC connected loads. The device is also equipped with three power rails for each signal, allowing for independent control of the high and low side switches and load drivers. It has the ability to control up to four low side switches independently of each other and up to eight high side switches in a single device.

The device also features a wide operating temperature range of -40°C to 125°C and a 32KHz PWM frequency. It contains a noise filter that provides low voltage ripple on the power rails and an overcurrent protection circuit to ensure reliable operation in harsh environments. Additionally, the device has a built-in thermal shutdown that prevents damage due to thermal overload.

Working with VN808CM-32-E starts with the selection of the power rails, followed by the selection of the low side switch and high side switch configurations. The device also allows for programming of the switching frequency and current limit settings. Once configured, the device can be used to control the power provided to the connected load.

The device also includes two analog comparators and four digital outputs, providing for feedback and logic control. The analog comparators provide control of the high and low side switches under programmable thresholds and can be used to switch on and off the power supply separately for each switch. The digital outputs can be used for a variety of applications, such as soft start and protection circuit. The device also includes a diagnostic pin, providing fault feedback to the user.

In conclusion, VN808CM-32-E is a highly versatile power management integrated circuit designed to control a wide variety of loads in many different applications. Its wide operating voltage range, programmability, and integrated features make it well suited for a wide range of applications. Additionally, the device features a relatively low cost and compact size, making it an attractive option for many designs.
