STMicroelectronics VNQ9080AJ Evaluation Board

STMicroelectronics VNQ9080AJ Evaluation Board comes pre-assembled with VNQ9080AJ high-side driver. The STMicroelectronics VNQ9080AJ board has a minimum set of electrical components enabling a direct connection to the load, power supply, and microcontroller. The VNQ9080AJ is a quad-channel high-side driver manufactured using ST proprietary VIPower M09 technology. The device is designed to drive 12V automotive grounded loads through a 3V and 5V CMOS-compatible interface, providing protection and diagnostics.

Features

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 3V and 5V 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 V_CC detection
- Sense enable/disable

Protections
- Undervoltage shutdown
