TB6564AHQ(THB6064AH)
TOSHIBA BiCD Integrated Circuit Silicon Monolithic
TB6564AHQ (THB6064AH)
PWM Chopper-Type bipolar
Stepping Motor Driver IC
The TB6564AHQ(THB6064AH) is a PWM chopper-type
sinusoidal micro-step bipolar stepping motor driver IC.
It supports 8 kind of excitation modes and forward/reverse mode
and is capable of low-vibration, high-performance drive of
2-phase bipolar type stepping motors using only a clock signal.
TB6564AHQ(THB6064AH)
Features
• Single-chip bipolar sinusoidal micro-step stepping motor
driver

• Uses high withstand voltage BiCD process:
Ron (upper lower) = 0.4 Ω (typ.)
HZIP25-P-1.27: 9.86 g (typ.)
• Forward and reverse rotation control available
• Selectable phase drive (1/2,1/8,1/10, 1/16, 1/20, 1/32, 1/40, 1/64 step)
• Output withstand voltage: VDSS = 50 V
• Output current: IOUT = 4.5 A (absolute maximum ratings, peak, within 100ms)
IOUT = 4.0 A (operating range, maximal value)
• Packages: HZIP25-P-1.27
• Output monitor pins (DOWN / ALERT)
• Equipped with reset and enable pins
• Built-in thermal shutdown(TSD) and over-current detection(ISD) circuit
The TB6564AHQ(THB6064AH) is a Sn-Ag plated product including Pb.
The following conditions apply to solderability:
*Solderability
1. Use of Sn-37Pb solder bath
*solder bath temperature = 230°C
*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 = 245°C
*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.

13.Thermal Shut-Down circuit
The IC incorporates a thermal shutdown circuit. When the junction temperature (Tj) reaches 170°C (typ.),
the output power MOSFETs are turned off.
The output power MOSFETs are turned on automatically.
The IC has 40°C of temperature hysteresis.

14. ISD (Over current detection)
Current that flow through output power MOSFETs are monitored individually. If over-current is detected in at
least one of all output power MOSFETs, all output power MOSFETs are turned off then this status is kept until
ENABLE signal is input. Target value in design is 6A and dispersion of ±1.5A should be considered.
