TOSHIBA BiCD Integrated Circuit Silicon Monolithic

TB6600FG

PWM Chopper-Type bipolar

Stepping Motor Driver IC

The TB6600FG is a PWM chopper-type single-chip bipolar sinusoidal

micro-step stepping motor driver.

TB6600FG

Forward and reverse rotation control is available with 2-phase,

1-2-phase, W1-2-phase, 2W1-2-phase, and 4W1-2-phase excitation

modes.

2-phase bipolar-type stepping motor can be driven by only clock signal

with low vibration and high efficiency.

Features

•

Single-chip bipolar sinusoidal micro-step stepping motor driver

Ron (upper + lower) = 0.4 Ω (typ.)

Weight:

Forward and reverse rotation control available

Selectable phase drive (1/1, 1/2, 1/4, 1/8, and 1/16 step)

Output withstand voltage: Vcc = 50 V

HQFP64-P-1010-0.50 : 0.26g( typ.)

Output current: I

= 4.5 A (absolute maximum ratings, peak)

= 4.0 A (operating range, maximal value)

OUT

•

Packages:HQFP64-P-1010-0.50

Built-in input pull-down resistance: 100 kΩ (typ.), (only TQ terminal: 70 kΩ(typ.))

Output monitor pins (ALERT): Maximum of I

= 1 mA

ALERT

= 1 mA

Output monitor pins (MO): Maximum of I

Equipped with reset and enable pins

Stand by function

Single power supply

Built-in thermal shutdown (TSD) circuit

Built-in under voltage lock out (UVLO) circuit

Built-in over-current detection (ISD) circuit(＊)

＊：Regarding ISD (over-current detection)：

Current that flows through output power MOSFETs are monitored individually. If the current exceeds

the over-current detection value in at least one of the eight output power MOSFETs, over-current is

detected and then L level is outputted as an ALERT signal. In this case, all output power MOSFETs

are turned off. However, always add a fuse in the power supply line because IC can be broken due to

the current being over absolute maximum ratings.
