A4984 DMOS Microstepping Driver with Translator And Overcurrent Protection Features and Benefits Description Low R outputs The A4984 is a complete microstepping motor driver with DS(ON) Automatic current decay mode detection/selection built-in translator for easy operation. It is designed to operate Mixed and Slow current decay modes bipolar stepper motors in full-, half-, quarter-, and eighth-step Synchronous rectification for low power dissipation modes. Step modes are selectable by MSx logic inputs. It has Internal UVLO an output drive capacity of up to 35 V and 2 A. The A4984 Crossover-current protection includes a fixed off-time current regulator which has the ability 3.3 and 5 V compatible logic supply to operate in Slow or Mixed decay modes. Thin profile QFN and TSSOP packages The ET package meets customer requirements for no smoke Thermal shutdown circuitry no fire (NSNF) designs by adding no-connect pins between Short-to-ground protection critical output, sense, and supply pins. So, in the case of a Shorted load protection pin-to-adjacent-pin short, the device does not cause smoke Low current Sleep mode, < 10 A or fire. Additionally, the device does not cause smoke or fire No smoke no fire (NSNF) compliance (ET package) when any pin is shorted to ground or left open. Packages: The translator is the key to the easy implementation of the A4984. Simply inputting one pulse on the STEP input drives 24-contact QFN the motor one microstep. There are no phase sequence tables, with exposed thermal pad high frequency control lines, or complex interfaces to program. 4 mm 4 mm 0.75 mm The A4984 interface is an ideal fit for applications where a (ES package) complex microprocessor is unavailable or is overburdened. During stepping operation, the chopping control in the A4984 32-contact QFN with exposed thermal pad automatically selects the current decay mode, Slow or Mixed. 5 mm 5 mm 0.90 mm (ET package) Continued on the next page 24-pin TSSOP with exposed thermal pad (LP Package) Typical Application Diagram V 0.1 F 0.1 F DD 0.22 F VREG ROSC CP1 CP2 VCP VBB1 0.22 F VDD 100 F VBB2 5 k Microcontroller or SLEEP OUT1A Controller Logic A4984 OUT1B STEP SENSE1 MS1 MS2 DIR OUT2A ENABLE OUT2B RESET SENSE2 VREF GND GND 4984-DS, Rev. 5DMOS Microstepping Driver with Translator A4984 And Overcurrent Protection Description (continued) In Mixed decay mode, the device is set initially to a fast decay for undervoltage lockout (UVLO), and crossover-current protection. a proportion of the fixed off-time, then to a slow decay for the Special power-on sequencing is not required. remainder of the off-time.
