SHIELD01 H-Bridge Arduino Shield

NVE Corporation's 40 V/50 A Arduino shield is ideal for motor speed and direction controls, DC-to-AC inverters, and robotics

Image of NVE Corporation's SHIELD01 H-Bridge Arduino ShieldNVE Corporation's SHIELD01 H-bridge Arduino shield features four power MOSFETs, four ultrahigh CMTI isolated MOSFET drivers, and two ultraminiature isolated DC-to-DC converters.

The two low-side IL610CMTI-1E isolators level-shift the Arduino outputs to six volts to drive the low-side MOSFETs. The high-side isolators drive the high-side MOSFETs, as the MOSFET source voltages float with the load. The two ILDC13-15E DC-to-DC converters generate floating 6 volt supplies referenced to the MOSFET source pins to power the high-side isolator/gate drivers.

The isolators have extremely high common-mode transient immunity (CMTI), so they do not glitch even when MOSFET source-pin voltages change rapidly as the MOSFETs switch. The resistors in series with the isolator input coils set the input current to approximately 12 mA. The resistor values maximize CMTI.
