5093 MMS ECM, Analog

Modular Micro Mezzanine System™ Electrical Conversion Module (ECM) Analog to Digital Converter - 2-channel power H bridge, 1 amp drive (RoHS Compliant Lead-free)


ECM P/N 5093 provides 2 independent full bridge circuits. The two full bridge circuits can be used together to drive one small two phase stepper motor. Each full bridge circuit can drive one small dc motor or other bipolar load. Note all inductive loads should employ transient protection. Each full bridge can be used as two high side switching half bridges with a single high side voltage. In this application one side of the load should be tied to GND. The positive high side voltage is supplied by the user on the input pins up to +30V. The board switches up to 4 loads to GND. In this application the high side voltages are connected to the loads and are independent of each other, but must be less than +30V. The half and full bridges can be wired in parallel to get greater current capacity. Negative voltages cannot be used as the high side voltage, as they will short out to GND via the body diode of the MOSFET. On resistance of the MOSFET is 0.010 ohms maximum. Voltages of +3V, +5V, +12V and -12V fused at 0.75 Amps are provided on the I/O pins. A serial identification circuit prevents use with incorrect FPGA IP.
