Power MOSFET design, providing
infinitely variable drive and plug brake control
silent high-frequency operation
high efficiency (for reduced motor and battery losses)
Overvoltage and undervoltage protection
Thermal protection/compensation circuitry that provides undertemperature cutback, constant current limit over operating range, and linear rollback in overtemperature-thus preventing sudden power loss regardless of thermal conditions
Diagnostic and test information for the controller-and other system components-readily available through both an on-board LED and the optional handheld programmer
Meets or exceeds EEC fault detect requirements, with circuitry and software to detect faults in the throttle circuit, MOSFET drive circuits, MOSFET output, contactor drivers, and contactors
Programmable input sequencing options include several combinations of neutral start and static return to off (SRO)
Arcless contactor switching with microprocessor-controlled contactor sequencing
Smooth, controlled plug braking-with either variable (throttledependent) or fixed plug current limit
Neutral braking option provides automatic plug braking in neutral
MultiMode™ input selects between two different operating modes, thus allowing optimization of vehicle characteristics for different driving conditions
Emergency reverse (belly button switch) provides full function with a single input
Anti-rollback (ramp start) provides full power for starting on ramps
Simple contactor and switch wiring, with coil drivers monitored for shorts and open circuits-thus ensuring fail-safe operation
Flexible throttle circuitry accommodates a variety of throttle types: 5kΩ–0, 0–5kΩ, 0–5V, 0–10V, inductive, Hall, etc.
Programmable "ramp shape" (static throttle map) provides flexibility in selecting throttle response feel
Sealed package, providing environmental protection
Power connections made by tin-plated solid copper busses, with a polarized Molex connector for control signals
Rugged anodized aluminum extruded housing meets IP65 environmental sealing standards for use in harsh environments.
