EV-VNH5180A VNH5180A evaluation board Data brief Description EV-VNH5180A provides you an easy way to connect ST’s surface mounted VIPower® H-Bridge drivers into your existing prototype circuitry. This evaluation board comes preassembled with VNH5180A-E H-Bridge. The VNH5180A-E is a system in package H-Bridge manufactured in the ST proprietary VIPower M0- 5 technology and housed in the PowerSSO-36 package. The VNH5180A-E is designed to drive 12 V automotive bidirectional load such as a PMDC motor. The VNH5180A-E provides protection, diagnostics and easy 3 V and 5 V CMOS-compatible interface with any microcontroller. Features Parameter Symbol Value Unit Max supply voltage Vcc 41 V Operating voltage range Vcc 5.5 to 18 V Max on-state resistance (per leg) RON 50 mΩ High-side current limitation (typ) IUMH 42 A Is 3 µA Off-state supply current • Simple single IC application board dedicated for VNH5180-E • Provides thermal heat-sinking for ease of use in prototyping The device integrates advanced protection functions such as load current limitation, inrush and active overload management by power limitation, overtemperature shut-off with autorestart and overvoltage active clamp. A dedicated analog current sense pin is associated with every output channel in order to provide Enhanced diagnostic functions including fast detection of overload and short-circuit to ground through power limitation indication, overtemperature indication, short-circuit to VCC protection and diagnosis as well as on-state and off-state open-load detection.The current sensing and diagnostic feedback of the whole device can be disabled by pulling the CS_DIS pin high to allow sharing of the external sense resistor with other similar devices. • Provides electrical connectivity for easy prototyping Table 1.

To make the H-Bridge the SOURCE_HSa pins must be electrically connected to the DRAIN_LSa pins. The same applies for the SOURCE_HSb and DRAIN_LSb pins. ST has produced a user manual for safe designs using ST’s VIPower devices. This is UM1556 (see Section Appendix A: Reference documents). UM1556 is a VIPower Hardware design guide that provides all of the necessary information to successfully design your circuit using our VIPower drivers. All designs have different needs and requirements. Whatever design you decide to use you will still need to verify that it meets your application needs. ST implies no guarantee or warranty (see Section Appendix A: Reference documents). DocID025032 Rev 3 5/12 11 Thermal data 2 EV-VNH5180A Thermal data Table 2.
