TB67S559FTG

Toshiba Electronic Devices & Storage Corporation ("Toshiba") has added a new product, “TB67S559FTG“ to its lineup of stepping motor driver IC series that support constant current control, for OA equipment and industrial equipment (robots, financial equipment, etc.) The new driver carries out constant current motor control without current sensing resistors. It is voltage/current ratings upgraded product and is compatible with pin/function of TB67S539FTG.

TB67S559FTG eliminates the need for external current sensing resistors by built-in a current detection part that is used for constant-current motor control.

The H-bridge circuit for motor control has an Nch/Nch configuration, and a built-in charge pump circuit for output stage control. Nch/Nch configuration generally requires an external capacitor for the charge pump, but the new product incorporates the external capacitor for the charge pump, eliminating the need for external components. This contributes to the reduction of external components and the space saving of the mounting area.

The package uses the same small P-VQFN32-0505-0.5 package as TB67S539FTG. In addition, pin/function compatibility makes it easy to replace from TB67S539FTG to TB67S559FTG without having to change the board when low heat and upgraded ratings are required.

It also supports 8.2V to 44V power supply for motor drive and can be used in a wide range of applications that require 12V drive and 36V drive as well as 24V drive applications.

Features

• Easy to replace from TB67S539FTG to TB67S559FTG without having to change the board when low heat and upgraded ratings are required.
• Small package (V-QFN32-0505-0.5)
• Low on-resistance (upper + lower) between the output transistor drain and source and reduced heat: Ron=0.4Ω (typ.)
• No need for current sensing resistors
• No need for an external capacitor for the charge pump circuit internally
• Low power consumption in sleep mode: IM1=1μA (max) (sleep mode)

Applications

• OA equipment, industrial equipment (robotics, financial equipment, etc.), POS terminals, vending machines, cameras, washing machines, sewing machines, projectors, faucets equipment
