EV-VNH5050A VNH5050A evaluation board Data brief Description EV-VNH5050A provides you an easy way to connect STs surface mounted VIPower HBridge drivers into your existing prototype circuitry. This evaluation board comes preassembled with VNH5050A-E H-Bridge. The VNH5050A-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 VNH5050A-E is designed to drive 12 V automotive bidirectional load such as a PMDC motor. The VNH5050A-E provides protection, diagnostics and easy 3 V and 5 V CMOS compatible interface with any microcontroller. Features The device integrates advanced protection functions such as load current limitation, inrush and active overload management by power Parameter Symbol Value Unit limitation, overtemperature shut-off with autorestart and overvoltage active clamp. A Max supply voltage V 41 V cc dedicated analog current sense pin is associated Operating voltage range V 5.5 to 18 V cc with every output channel in order to provide Max on-state resistance Enhanced diagnostic functions including fast R 50 m ON (per leg) detection of overload and short-circuit to ground through power limitation indication, over- High-side current I 42 A UMH temperature indication, short-circuit to V limitation (typ) CC protection and diagnosis as well as on-state and Off-state supply current I 3A s off-state open-load detection. The current sensing and diagnostic feedback of Simple single IC application board dedicated the whole device can be disabled by pulling the for VNH5050-E CS DIS pin high to allow sharing of the external Provides thermal heat-sinking for ease of use sense resistor with other similar devices. in prototyping Provides electrical connectivity for easy prototyping Table 1.
