Overview
The VND5160AJ-E is a monolithic device manufactured by STMicroelectronics using their VIPower technology. It is designed to drive resistive or inductive loads with one side connected to ground. This device is particularly suited for automotive applications and features active inrush current management, very low standby current, and 3.0V CMOS compatible inputs. It also includes optimized electromagnetic emission and very low electromagnetic susceptibility, ensuring compliance with the 2002/95/EC European directive.
The device integrates an analog current sense that delivers a current proportional to the load current, and it includes various protection mechanisms such as undervoltage shutdown, overvoltage clamp, load current limitation, and thermal shutdown with automatic restart.
