TB6591FLG
DC Motor Driver
The TB6591FLG is a DC motor driver IC using LDMOS output
transistors with low ON-resistance.
The TB6591FLG incorporates one constant-current
PWM-controlled, chopper-type bridge driver, and three
voltage-regulated stepping motor drivers (six bridge drivers) that
support 2-phase and 1-2-phase excitation modes. The TB6591FLG
enables camera motor control for zoom lenses, auto focus and
shutter control.
Features
Supply voltage for motor: VM ≤ 6 V (max)
Supply voltage for control block: VCC = 2.7 to 6 V
Output current: IOUT ≤ 0.8 A (max)
Push-pull outputs consisting of P-channel and N-channel LDMOS transistors
Low ON-resistance: RON = 1.5 (upper and lower sum at VM = 5 V, VCC = 5 V typ.)
Constant-current driver for PWM chopper control: fosc ≤ 100 kHz
Voltage-regulated driver for direct PWM control: fpwm ≤ 10 kHz (duty cycle = 10% to 90%)
Standby (power-save) mode
Thermal shutdown (TSD)
Small package: QON48
*: 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: 0.1 g (typ.)
The TB6591FLG is RoHS-compatible
