The VNQ5050AK-E is a quad channel high side driver with analog current sense for automotive applications. It features inrush current active management, very low standby current, and optimized electromagnetic emission. The device also provides various protection functions including undervoltage shutdown, overvoltage clamp, load current limitation, and thermal shutdown. It is suitable for driving resistive, inductive, and capacitive loads, and can also be used as an LED driver.
The VNQ5050AK-E is a monolithic device utilizing VIPower MO0-5 technology intended for driving resistive or inductive loads where one side is connected to ground. It features four independent channels, each equipped with an active power switch and an analog current sense function that delivers a current proportional to the load current when enabled.
The device includes comprehensive protection mechanisms such as undervoltage shutdown, overvoltage clamp, load current limitation, thermal shutdown, and reverse battery protection. It is optimized for automotive environments with features like inrush current management via power limitation and compliance with relevant European directives regarding hazardous substances.
