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.
Features Motor power supply voltage: VM ≤ 6 V (max) Control power supply voltage: VCC = 2.7 to 6 V Output current: IOUT ≤ 0.8 A (max) Complementary P- and N-channel LDMOS output transistors Output ON-resistance: RON (upper and lower sum at) = 1.5 Ω (typ.)
Channels D and E: Constant-current H-bridge drivers Produces low-ripple current with high-speed PWM control at several hundred kHz
Channels A, B and C: Stepping motor drivers Three H-bridge drivers for direct PWM control
Other Features 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.
Weight: 0.08 g (typ.)
The TB6607FLG is a Pb-free product.
