TB6562ANG/AFG TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB6562ANG/AFG Dual Full-Bridge Driver IC for Stepping Motors The TB6562ANG/AFG is a 2-phase bipolar stepping motor driver TB6562ANG that contains DMOS transistors in the output stage. The driver achieves high efficiency through the use of low ON-resistance DMOS transistors and PWM current control circuitry. Features 2-phase/12-phase/W 12-phase excitation PWM current control Power supply voltage: 40 V (max) Output current: 1.5 A (max) TB6562AFG Low ON-resistance: 1.5 (upper and lower transistors/typ.) Power-saving function Overcurrent protection: I = 2.5 A (typ.) LIM Thermal shutdown Package: TB6562ANG SDIP24-P-300-1.78 TB6562AFG SSOP30-P-375-1.00 SSOP30-P- 375-1.00 Weight: SDIP24-P-300-1.78: 1.62 g (typ.) SSOP30-P-375-1.00: 0.63 g (typ.) This product has a MOS structure and is sensitive to electrostatic discharge. When handling the product, ensure that the environment is protected against electrostatic discharge by using an earth strap, a conductive mat and an ionizer. Ensure also that the ambient temperature and relative humidity are maintained at reasonable levels. Special care should be taken with the following pins, which are vulnerable to surge current. Pins with low surge withstand capability: TB6562ANG: pins 10, 15 TB6562AFG: pins 13, 18 1 2012-09-28 TB6562ANG/AFG Block Diagram Some functional blocks, circuits, or constants may be omitted or simplified in the block diagram for explanatory purposes. < TB6562ANG > V V V GND SB OSC V OUT2A OUT1A OUT2B OUT1B GND reg CC CC CC 24 2 3 22 23 11 7 8 14 18 17 13 OSC 5 V Waveform squaring circuit Thermal shutdown Control logic Decoder 1 4 5 6 21 20 19 9 10 16 15 12 GND Phase A X1A X2A Phase B X1B X2B VARSA VB RSB GND ref ref < TB6562AFG > V V V GND SB OSC V OUT2A OUT1A OUT2B OUT1B GND reg CC CC CC 30 2 3 28 29 14 10 11 17 21 20 16, 22, 23, 24 OSC 5 V Waveform squaring circuit Thermal shutdown Control logic Decoder 1 4 5 6 27 26 25 12 13 19 18 7, 8, 9, 15 GND Phase A X1A X2A Phase B X1B X2B VARSA VB RSB GND ref ref 2 2012-09-28
