Toshiba Introduces Stepping Motor Driver IC “TB67S10xA” Series – Jul 12, 2013– Tokyo, Japan  (Techreleased) – Toshiba Corporation today announced the launch of the “TB67S10xA” series of stepping motor driver ICs that realize high voltage, high current and low heat-generation. Sample shipment will start on July 17.

Toshiba TB67S10xA Series

High speed, high power motor drives are required in applications that include printers and other office automation equipment, ATMs, banknote counters, amusement machines, and home appliances. These applications are shrinking in size through space-saving and design improvement, making heat management increasingly important.

The “TB67S10xA” series, fabricated with the latest high voltage analog process, offers 50V maximum rating and low on resistance^[1] during motor driver output (0.5Ω or less, total of upper and lower side) to reduce heat. Newly developed motor driving technology (ADMD^[2]) improves switching speed, contributing to lower heat generation and higher drive efficiency.

Key features of the new product series

Low heat-generation

Low on resistance (0.5Ω or less, total of upper and lower side) and ADMD technology reduce heat generation

Low vibration and low noise

The high-end product in the series, “TB67S109A”, uses high-resolution 1/32 step (max.) motor driving technology that reduces vibration and noise.

Small package with good heat dissipation

A small, effective heat-dissipating package simplifies heat management of applications and also contributes to downsizing and cost reduction. The series offers two package line-ups: the HTSSOP package is pin-compatible with equivalent products, and QFN package reduces mounting area.

Built-in abnormality detection functions

The product series integrates a thermal shutdown circuit, overcurrent shutdown circuit, and undervoltage lockout circuit, and realizes high reliability.
