VQ9XV97 Automotive Body Controller LED Driver IC – High-Side Lighting Power Switch with Analog Current Sense

The VQ9XV97 is a monolithic high-side driver fabricated with advanced VIPower technology, specifically designed for automotive body control module lighting applications.
It is engineered to drive resistive, inductive, and capacitive loads with one side connected to ground, making it ideal for exterior and interior lighting systems including headlights, tail lights, and DRLs.
This single-channel smart driver integrates a very low on-state resistance power MOSFET, enabling high-current switching with minimal power dissipation for demanding lighting loads.
The device features an analog current sense output that delivers a current precisely proportional to the load current, providing accurate diagnostic monitoring capability.
Inrush current is actively managed through built-in power limitation, protecting the system from surge damage during cold lamp filament startup or capacitive load charging.
Comprehensive protection features include overvoltage clamp, load current limitation, and thermal shutdown with automatic restart for fault tolerance.
The chip is safeguarded against loss of ground, loss of VCC, and reverse battery conditions, ensuring robust operation in harsh automotive electrical environments.
Undervoltage shutdown prevents malfunction during low supply voltage conditions, while electrostatic discharge protection guards against handling damage.
With a wide operating voltage range compatible with 12V and 24V vehicle electrical systems, this driver adapts to various platform requirements.
The very low standby current consumption minimizes battery drain when the system is in idle or sleep mode.
Electromagnetic emission is optimized for automotive compliance, and the device exhibits excellent electromagnetic immunity for stable operation in electrically noisy environments.
A current sense disable function allows the diagnostic output to be placed in a high-impedance state when not required, reducing system power consumption.
The device is qualified to AEC-Q100 automotive-grade standards, with a junction temperature range of -40°C to 150°C for extreme under-hood durability.
This fully protected high-side LED driver delivers the performance, diagnostics, and reliability required for modern body control module lighting applications.
