Description
The VNQ9025AJ is a quad channel high-side driver manufactured using ST proprietary VIPower M0-9 technology and housed in PowerSSO-16 package. The device is designed to drive 12 V automotive grounded loads through a 3 V and 5 V CMOS-compatible interface, providing protection and diagnostics.
Features
• AEC-Q100 qualified
• Extreme low voltage operation for deep cold cranking applications (compliant
with LV124, revision 2013)
• General
– Quad channel smart high-side driver with current sense analog feedback
– Very low standby current
– Compatible with 3 V and 5 V CMOS outputs
• Current sense diagnostic functions
– Multiplexed analog feedback of load current with high precision proportional
current mirror
– Overload and short to ground (power limitation) indication
– Thermal shutdown indication
– OFF-state open-load detection (with external pull-up)
– Output short to VCC detection
– Sense enable/disable
• Protections
– Undervoltage shutdown
– Overvoltage clamp
– Load current limitation
– Self limiting of fast thermal transients
– Configurable latch-off on overtemperature or power limitation with
dedicated fault reset pin
– Loss of ground and loss of VCC
– Reverse battery through self turn-on
– Electrostatic discharge protection
Applications
• Automotive resistive, inductive and capacitive loads
• Protected supply for ADAS systems: radars and sensors
• Automotive lamps: P27W or SAE1156
