VN7020A Automotive High-Side Driver with MultiSense Analog Feedback for Turn Signal and Relay Control - PowerSSO-16 Package
This device is a single-channel high-side driver manufactured using advanced VIPower M0-7 technology, specifically designed for automotive applications.
It is housed in a compact PowerSSO-16 package and is fully AEC-Q100 qualified for reliable operation in harsh vehicle environments .
The chip operates across a wide supply voltage range from 4V to 28V, with a maximum transient tolerance of 40V, making it suitable for 12V automotive electrical systems .
It features an extremely low typical on-resistance of just 20mΩ, which minimizes power dissipation and heat generation during operation .
The integrated current limitation is typically 63A, with a maximum output current capability of 45A, providing robust load driving capacity .
The device is compatible with both 3V and 5V CMOS logic interfaces, allowing direct connection to microcontrollers without level shifting .
An innovative MultiSense analog feedback pin delivers sophisticated diagnostic functions, including high-precision proportional load current sensing, supply voltage feedback, and chip temperature monitoring .
Advanced protection features include load current limitation, overload active management through power limitation, overtemperature shutdown with configurable latch-off, and undervoltage shutdown .
Additional diagnostics cover overload and short-to-ground detection, thermal shutdown indication, OFF-state open-load detection, and output short-to-VCC detection .
The FaultRST pin allows unlatching the output in fault conditions or disabling the latch-off functionality as needed .
The device also supports a very low standby current of just 0.5µA, making it ideal for always-connected automotive modules .
Common applications include automotive turn signal lamps, relay drivers, and ADAS system power protection such as radar and sensor modules .
This component operates reliably over an extended temperature range from -40°C to +150°C, suitable for under-hood and body electronics applications .
