TB6560AHQ/AFG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB6560AHQ, TB6560AFG PWM Chopper-Type Bipolar Driver IC for Stepping Motor Control The TB6560AHQ/AFG is a PWM chopper-type stepping motor TB6560AHQ driver IC designed for sinusoidal-input microstep control of bipolar stepping motors. The TB6560AHQ/AFG can be used in applications that require 2-phase, 1-2-phase, 2W1-2-phase and 4W1-2-phase excitation modes. The TB6560AHQ/AFG is capable of low-vibration, high-performance forward and reverse driving of a two-phase bipolar stepping motor using only a clock signal. Features TB6560AFG Single-chip motor driver for sinusoidal microstep control of stepping motors High output withstand voltage due to the use of BiCD process: Ron (upper and lower sum) = TB6560AHQ: 0.6 (typ.) TB6560AFG: 0.7 (typ.) Forward and reverse rotation Selectable phase excitation modes (2, 1-2, 2W1-2 and 4W1-2) High output withstand voltage: V = 40 V DSS Weight High output current: I = TB6560AHQ: 3.5 A (peak) OUT HZIP25-P-1.27: 9.86 g (typ.) TB6560AFG: 2.5 A (peak) HQFP64-P-1010-0.50: 0.26 g (typ.) Packages: HZIP25-P-1.27 HQFP64-P-1010-0.50 Internal pull-down resistors on inputs: 100 k (typ.) Output monitor pin: M current (I (max) = 1 mA) O MO Reset and enable pins Thermal shutdown (TSD) *Solderability 1. Use of Sn-37Pb solder bath *solder bath temperature = 230C *dipping time = 5 seconds *number of times = once *use of R-type flux 2. Use of Sn-3.0Ag-0.5Cu solder bath *solder bath temperature = 245C *dipping time = 5 seconds *the number of times = once *use of R-type flux *: These ICs are highly sensitive to electrostatic discharge. When handling them, ensure that the environment is protected against electrostatic discharge. Ensure also that the ambient temperature and relative humidity are maintained at reasonable level. 1 2011-01-18 TB6560AHQ/AFG Block Diagram V Protect M VM DD O A 20/30, 31 19/28 17/23 18/25, 26 OUT AP M1 23/36 16/19, 20 PWM Bridge control driver A M2 22/35 circuit 13/10, 11 OUT AM CW/CCW 21/33 N Thermal shutdown FA 14/13, 14 CLK 3/45 circuit Input circuit RESET 5/48 8/55, 56 VM B ENABLE 4/47 OUT BP DCY1 25/39 12/6, 7 PWM Bridge control driver B DCY2 24/38 circuit 9/61, 62 OUT BM OSC 7/53 OSC N FB 11/2, 4 Maximum current setting circuit 2/43 1/42 6/50, 51 15/16 10/64 TQ1 TQ2 SGND PGNDA PGNDB TB6560AHQ/TB6560AFG 2 2011-01-18
