TOSHIBA BiCD Integrated Circuit Silicon Monolithic
TB6613FTG
DC and Stepping Motor Driver
TB6613FTG
The TB6613FTG is a DC motor driver IC using LDMOS output
transistors with low ON-resistance.
The TB6613FTG incorporates five PWM constant-current
H-bridge drivers, of which four drivers can be used for micro
stepping motor drives of up to two stepping motors.
The TB6613FTG is best suited to control various lens actuators
in digital still cameras.
The three-wire serial interface provides control over the drivers,
thus reducing the number of lines required for interfacing with
the control IC.
Weight: 0.05 g (typ.)
Features
• Motor power supply voltage: VM ≤ 6 V (max)
• Control power supply voltage: VCC = 3 V to 5.5 V
• Output current: IOUT ≤ 0.8 A (max)
• Complementally P- and N-channel LDMOS output transistors
• Output ON-resistance: RON (upper and lower sum) = 1.5 Ω (@VM = VCC = 5 V typ.)
Channels A, B, C and D
• Four H-bridge drivers capable of PWM constant-current control
Supports up to two two-phase bipolar stepping motors (STMs) or up to four actuators.
• Each channel is individually configurable for either H-Bridge mode or STM μStep mode via the serial
interface.
• In STM μStep mode, the micro stepping resolution is selectable from 6 bits (256 steps per full cycle) or 1 bit (8
steps per full cycle).
Channel E
• One PWM constant-current driver
• The constant-current reference voltage (Vref) is programmable via the internal 6-bit DAC.
Other Features
• Each channel has a DAC for setting constant-current values (Channels A to D = 2 bits in H-Bridge mode and
2 bits × 6 bits in μStep mode; Channel E = 6 bits)
• Dedicated standby (power-save) pin
• Thermal shutdown (TSD)
• Undervoltage lockout (UVLO): Resets and disables the internal circuitry when VCC falls below 2.2 V (typ.).
• Small VQON44 package (0.4-mm lead pitch)
Note: This product has a MOS structure and is sensitive to electrostatic discharge. When handling this 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.
