Description
The A4982 is a complete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and sixteenth-step modes, with an output drive capacity of up to 35 V and ±2 A.
The A4982 includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes. The ET package meets customer requirements for no smoke no fire (NSNF) designs by adding no-connect pins between critical output, sense, and supply pins. So, in the case of a pin-to-adjacent-pin short, the device does not cause smoke or fire.
Additionally, the device does not cause smoke or fire when any pin is shorted to ground or left open. The translator is the key to the easy implementation of the A4982. Simply inputting one pulse on the STEP input drives the motor one microstep.
There are no phase sequence tables, high frequency control lines, or complex interfaces to program. The A4982 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.
During stepping operation, the chopping control in the A4982 automatically selects the current decay mode, Slow or Mixed.
