4 / 26 page L6228 4/26 PIN DESCRIPTION PACKAGE Name Type Function SO24/ PowerDIP24 PowerSO36 PIN # PIN # 1 10 CLOCK Logic Input Step Clock input. The state machine makes one step on each rising edge. 2 11 CW/CCW Logic Input Selects the direction of the rotation. HIGH logic level sets clockwise direction, whereas LOW logic level sets counterclockwise direction. If not used, it has to be connected to GND or +5V. 3 12 SENSEA Power Supply Bridge A Source Pin. This pin must be connected to Power Ground through a sensing power resistor. 413 RCA RC Pin RC Network Pin. A parallel RC network connected between this pin and ground sets the Current Controller OFF-Time of the Bridge A. 5 15 OUT1A Power Output Bridge A Output 1. 6, 7, 18, 19 1, 18, 19, 36 GND GND Ground terminals. In PowerDIP24 and SO24 packages, these pins are also used for heat dissipation toward the PCB. On PowerSO36 package the slug is connected to these pins. 8 22 OUT1B Power Output Bridge B Output 1. 924 RCB RC Pin RC Network Pin. A parallel RC network connected between this pin and ground sets the Current Controller OFF-Time of the Bridge B. 10 25 SENSEB Power Supply Bridge B Source Pin. This pin must be connected to Power Ground through a sensing power resistor. 11 26 VREFB Analog Input Bridge B Current Controller Reference Voltage. Do not leave this pin open or connected to GND. 12 27 HALF/FULL Logic Input Step Mode Selector. HIGH logic level sets HALF STEP Mode, LOW logic level sets FULL STEP Mode. If not used, it has to be connected to GND or +5V. 13 28 CONTROL Logic Input Decay Mode Selector. HIGH logic level sets SLOW DECAY Mode. LOW logic level sets FAST DECAY Mode. If not used, it has to be connected to GND or +5V. 14 29 EN Logic Input (6) Chip Enable. LOW logic level switches OFF all Power MOSFETs of both Bridge A and Bridge B. This pin is also connected to the collector of the Overcurrent and Thermal Protection to implement over current protection. If not used, it has to be connected to +5V through a resistor. 15 30 VBOOT Supply Voltage Bootstrap Voltage needed for driving the upper Power MOSFETs of both Bridge A and Bridge B. 16 32 OUT2B Power Output Bridge B Output 2. 17 33 VSB Power Supply Bridge B Power Supply Voltage. It must be connected to the Supply Voltage together with pin VSA 20 4 VSA Power Supply Bridge A Power Supply Voltage. It must be connected to the Supply Voltage together with pin VSB |
