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.
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.)
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.)
