1.4 Device Information

The AMC-AMP-50A-EVM is designed to provide ease-of-use and high accuracy in large current applications. The current-sensing device, AMC3302, is an isolated amplifier intended for shunt-based current sensing with reinforced isolation and an integrated DC/DC converter. Overcurrent detection is configurable using the AMC23C15, a reinforced, adjustable threshold isolated comparator. Both isolated current-sensing products sense across the BVN-M-R001 shunt resistor. The EVM features an additional unpopulated shunt resistor footprint in parallel to extend the current sensing range flexibility. See Section 3 for details. Included in the EVM kit are high-current lug connectors used for supplying primary current to be sensed to the EVM.
