TB6607FLG
DC and Stepping Motor Driver IC
The TB6607FLG is a DC motor driver IC using LDMOS output
transistors with low ON-resistance.
The TB6607FLG incorporates two PWM-controlled,
constant-current H-bridge drivers and three
direct-PWM-controlled H-bridge drivers. The TB6607FLG is best
suited to control various lens actuators in digital still cameras.
The drivers of the TB6607FLG are controlled via a three-wire
serial interface, thus reducing the number of lines required for
interfacing with the control IC.
Weight: 0.08 g (typ.)

Produces low-ripple current with high-speed PWM control at several hundred kHz
Three H-bridge drivers for direct PWM control
Two 6-bit DACs provide reference values for constant-current limiters
Independent Standby (power-save) mode
Thermal shutdown (TSD): Disables the output bias generator when the internal junction temperature exceeds
170°C.
Undervoltage lockout (UVLO): Resets and disables the internal circuitry when VCC falls below 2.2 V (typ.)
Small QON-36 package (0.5-mm lead pitch)
Compatible with Pb-free reflow soldering
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.
The TB6607FLG is a Pb-free product.
