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 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/1- 2-phase/W 1- 2-phase excitation PWM current control Power supply voltage: 40 V (max) Output current: 1.5 A (max) Low ON-resistance: 1.5 Ω (upper and lower transistors/typ.) Power-saving function Overcurrent protection: ILIM = 2.5 A (typ.) Thermal shutdown Package: TB6562ANG; SDIP24-P-300-1.78 TB6562AFG; SSOP30-P-375-1.00 TB6562ANG 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 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 > Vreg VCC OUT2A VCC OUT1A OUT2B VCC OUT1B GND 5V Thermal shutdown OSC Waveform squaring circuit Control logic Decoder GND Phase A X1A X2A Phase B X1B X2B Vref A RSA Vref B RSB GND < TB6562AFG > Vreg VCC OUT2A VCC OUT1A OUT2B VCC OUT1B...
