Simple single IC application board dedicated for VNQ5E050AK-E Provides thermal heat-sinking for ease of use in prototyping Provides electrical connectivity for easy prototyping Description EV-VNQ5E050AK provides you an easy way to connect STs surface mounted VIPower drivers into your existing prototype circuitry. This evaluation board comes pre-assembled with VNQ5E050AK-E high-side driver. The VNQ5E050AK-E is a quad channel high-side driver manufactured using ST proprietary VIPower M0-5 technology and housed in PowerSSO-24 package. The VNQ5E050AK-E is designed to drive 12 V automotive grounded loads, providing protection, diagnostics and easy 3 V and 5 V CMOS-compatible interface with any microcontroller. The device integrates advanced protective Table 1.

This is UM1556 (see Appendix A: Reference documents). UM1556 is a VIPower Hardware design guide that provides all necessary information to successfully design your circuit using our VIPower drivers. All designs have different needs and requirements. Whatever design you decide to use, it will still need to be verified in order to meet your application specifications.
