TB6600FG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB6600FG PWM Chopper-Type bipolar Stepping Motor Driver IC The TB6600FG is a PWM chopper-type single-chip bipolar sinusoidal TB6600FG micro-step stepping motor driver. Forward and reverse rotation control is available with 2-phase, 1-2-phase, W1-2-phase, 2W1-2-phase, and 4W1-2-phase excitation modes. 2-phase bipolar-type stepping motor can be driven by only clock signal with low vibration and high efficiency. Features Single-chip bipolar sinusoidal micro-step stepping motor driver Ron (upper + lower) = 0.4 (typ.) Weight: Forward and reverse rotation control available HQFP64-P-1010-0.50 : 0.26g( typ.) Selectable phase drive (1/1, 1/2, 1/4, 1/8, and 1/16 step) Output withstand voltage: Vcc = 50 V Output current: I = 4.5 A (absolute maximum ratings, peak) OUT I = 4.0 A (operating range, maximal value) OUT Packages:HQFP64-P-1010-0.50 Built-in input pull-down resistance: 100 k (typ.), (only TQ terminal: 70 k(typ.)) Output monitor pins (ALERT): Maximum of I = 1 mA ALERT Output monitor pins (MO): Maximum of I = 1 mA MO Equipped with reset and enable pins Stand by function Single power supply Built-in thermal shutdown (TSD) circuit Built-in under voltage lock out (UVLO) circuit Built-in over-current detection (ISD) circuit() Regarding ISD (over-current detection) Current that flows through output power MOSFETs are monitored individually. If the current exceeds the over-current detection value in at least one of the eight output power MOSFETs, over-current is detected and then L level is outputted as an ALERT signal. In this case, all output power MOSFETs are turned off. However, always add a fuse in the power supply line because IC can be broken due to the current being over absolute maximum ratings. 1 2014-03-03 TB6600FG Pin Functions Pin No. I/O Symbol Functional Description Remark 43 Output ALERT TSD / ISD monitor pin Pull-up by external resistance 45 SGND Signal ground 47 Input TQ Torque (output current) setting input pin 49 Input Select a return type for TSD.
