Typical value with all loads connected. Simple single IC application board dedicated for VNQ5027AK-E Provides thermal heat-sinking for ease of use in prototyping Provides electrical connectivity for easy prototyping Description EV-VNQ5027AK provides you an easy way to connect STs surface mounted VIPower drivers into your existing prototype circuitry. This evaluation board comes pre-assembled with VNQ5027AK-E high-side driver. The VNQ5027AK-E is a monolitic device made using STMicroelectronics VIPower technology. It is intended for driving resistive or inductive loads with one side connected to ground. Active V pin CC voltage clamp protects the device against low energy spikes. This device integrates an analog current sense which delivers a current proportional to the load current (according to a known ratio) when Table 1. Device summary CS DIS is driven low or left open. When CS DIS Order code Reference is driven high, the CURRENT SENSE pin is in a high impedance condition. Output current EV-VNQ5027AK VNQ5027AK evaluation board limitation protects the device in overload condition.

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.
