VN5010AK-E High-Side Driver IC – Automotive Lighting Power Switch with Analog Current Sense

The VN5010AK-E is a monolithic high-side driver fabricated with advanced VIPower M0-5 technology for demanding automotive applications.
It is specifically designed to drive resistive, inductive, and capacitive loads with one side connected to ground, making it ideal for headlight and high-beam lighting systems.
This single-channel driver integrates a very low on-state resistance of just 10 mΩ, enabling high-current switching with minimal power dissipation.
The device features an analog current sense output that delivers a current proportional to the load current for precise diagnostic monitoring.
Inrush current is actively managed through built-in power limitation, protecting the system from surge damage during lamp startup.
Comprehensive protection features include overvoltage clamp, load current limitation, and thermal shutdown with automatic restart.
The chip is safeguarded against loss of ground, loss of VCC, and reverse battery conditions, ensuring reliable operation in harsh automotive environments.
Undervoltage shutdown prevents malfunction during low supply voltage conditions, while ESD protection guards against electrostatic discharge damage.
With a wide operating voltage range of 4.5V to 36V, this driver is compatible with 12V and 24V vehicle electrical systems.
The very low standby current of just 2 µA minimizes power consumption when the system is idle.
Electromagnetic emission is optimized, and the device exhibits very low electromagnetic susceptibility for stable operation in noisy environments.
A current sense disable function allows the diagnostic output to be placed in a high-impedance state when not in use.
The device is qualified to automotive-grade standards with an operating junction temperature range of -40°C to 150°C.
This fully protected high-side driver delivers the performance and reliability required for modern automotive lighting and body control modules.
