TB6613FTG

TB6613FTG TOSHIBA BiCD Integrated Circuit Silicon Monolithic TB6613FTG DC and Stepping Motor Driver 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 ...
