EV-VNH5050A VNH5050A Evaluation Board

EV-VNH5050A provides you an easy way to connect ST’s 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 packageH-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.

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, over-temperature indication, short-circuit to VCCprotection 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 CSDIS pin high to allow sharing of the external sense resistor with other similar devices.
