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 CS_DIS pin high to allow sharing of the external sense resistor with other similar devices.
