AN4210 Application note PowerSSO-12 devices evaluation board Introduction The EV board concept is intended to provide customers with an easy way to connect ST's surface mounted VIPower® drivers into their existing prototype circuitry. The EV boards come pre-assembled with one of ST's VIPower high-side drivers. Figure 1. PowerSSO-12 evaluation board These boards provide mounting solutions and some heat sinking capability for prototype development. There are still external components required to make these devices work in any application. Figure 2. PowerSSO-12 package This document provides application schematics for the following evaluation boards: Table 1.

The schematics provided in this document are recommended for their proper functionality. 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. ST implies no guarantee or warranty (see Appendix A: Reference documents). Note: When more than one pin is used for an output, all output pins must be tied together for proper operation. ST has produced two user manuals: the UM1556 (for 12 V devices) and the UM1557 (for 24 V devices) (see Appendix A: Reference documents). Those user manuals are VIPower hardware design guides that provide the necessary information to successfully design your circuit using our VIPower drivers. 1.1 Digital feedback designs These devices have a logic level fault pin that is pulled low when a fault is detected and the status disable (STAT_DIS) pin is held low. The feedback is an open Drain configuration and requires a pull-up resistor for proper operation. For this package type (PowerSSO-12) there are single, and dual output devices. Figure 3.

The maximum voltage rating for this device is elevated from the standard 41 V to 58 V. 24 V products are equipped with a latch-off feature keeping the device switched-off once power limitation or thermal shutdown is triggered. This latch can be activated by holding the FR_STBY pin high. Resetting the device to retry the load requires pulling the FR_STBY pin low. Leaving the FR_STBY pin low disables the latch off feature and lets the part automatically retry shorted loads. More details can be found in the user manual UM1557 (see Appendix A: Reference documents). Figure 12.
