Description: T
his is essentially a ramped up version of our Ardumoto motor driver
shield. For this SparkFun Monster Moto Shield we’ve replaced the L298 H-bridge with
a pair of VNH2SP30 full-bridge motor drivers. We’ve also beefed up the support
circuitry so this board is capable of driving a pair of high-current motors! The VIN and
motor out are pitched for our 5mm screw terminals (not included), making it easy to
connect larger gauge wires.
Note: When using this board in extreme high-demand applications it may be
necessary to improve thermal performance with a heat-sink or fan and to solder the
wires directly to the board instead of using a screw terminal (in addition to the myriad
other complications present in a high-current system) However, when using the board
at currents up to 6A the chips will barely become noticeably warm.
Features:
• Voltage max: 16V
• Maximum current rating: 30 A
• Practical Continuous Current: 14 A
• Current sensing available to Arduino analog pin
• MOSFET on-resistance: 19 mΩ (per leg)
• Maximum PWM frequency: 20 kHz
• Thermal Shutdown
• Undervoltage and Overvoltage shutdown
