Toshiba Launches Bipolar 2-channel Stepping Motor Driver with Maximum Rating of 40V and 2.0A

TOKYO--(BUSINESS WIRE)--Toshiba Corporation's (TOKYO:6502) Semiconductor & Storage Products Company today announced the launch of "TC78S122FNG," a bipolar 2-channel stepping motor driver offering a high voltage of 40V and current of 2.0A. Sample shipment starts today, with mass production scheduled to start in July 2016.

High speed, high performance motor drives are required for applications such as printers, surveillance cameras, office automation equipment, banking terminals such as ATMs, banknote identification machines, amusement machines, and home appliances. In parallel, the downsizing of equipment is being accelerated by customer demand for space-saving equipment with excellent design. Measures to reduce heat generated inside equipment and low power consumption of the overall unit are also growing in importance.

Toshiba’s new product has a 2-channel drive function in a two-in-one chip and is capable of running two stepping motors simultaneously. Space can be saved on circuit boards by integrating electronic components as 2-in-1 chips.

Because of the heat generated by the ICs themselves, the previous products could not achieve continuous operation in the driving current range of 2.0A motors that are used in many applications, including office equipment. The new product can simultaneously drive two channels by reducing the output resistance by 50% to cut heat generation*1.

While the regulator circuit for the IC's internal logic in the previous products was in operation at stand-by, the new product can stop the regulator at stand-by, due to incorporation of a sleep function. Consequently, power consumption of the IC is reduced.

Moreover, the new product not only drives stepping motors, it also provides interface for driving brushed DC motors. This provides various combinations of stepping motors and brushed DC motors; for example one channel of stepping motor and two channels of brushed DC motors. By enhancing its product line-up, Toshiba offers a variety of selections to meet various requirements for motor drive applications.

Main Feature of New Product

Low heat generation
Heat generation of the 2-channel simultaneous drive is reduced by low on resistance (0.6Ω or less, upper + lower).
Low vibration and low noise
High-resolution motor driving technology of 1/4 steps (max.) and decay mode switching function for constant-current control are adopted to reduce vibration and noise.
Low power consumption
A built-in sleep function by external pin control reduces the IC current consumption at stand-by.
Small package
Heat treatment of the equipment and the module can be simplified by adopting a small and high heat radiation HTSSOP package. This can contribute to downsizing the IC and reduce the cost. Toshiba also plans to release a QFN package, which is a more compact package.
Build-in error detection circuits
The new product incorporates a thermal shutdown and an overcurrent shutdown circuit. The safety and the reliability of the equipment are increased by the signals they output during equipment design.
Applications
Industrial equipment (surveillance cameras, banking terminals such as ATMs, office- and factory-automation equipment), amusement machines (pachinko and video slot machines), and home appliances (refrigerators and air conditioners)

东芝推出双极2通道步进电机驱动器

东京 - (美国商业资讯) - 东芝公司(东京证券交易所:6502)半导体&存储产品公司今天宣布推出“TC78S122FNG,”双极2通道步进电机驱动器,提供40V的高电压和电流2.0A的。样品供货今天开始批量生产预计于今年七月2016年开始。

高速,需要用于应用如打印机,监控摄像机,办公自动化设备,银行终端,诸如自动柜员机,纸币识别机,娱乐机器,家电高性能马达驱动器。同时,设备的小型化是由客户需求为节省空间的设备,优秀的设计加速。措施,以减少内部的设备和总的单元的低功耗也越来越重要产生的热量。

东芝的新产品有两个功能于一身的芯片双通道驱动功能,并能够同时运行两个步进电机。空间可以通过集成电子元件如2合1片被保存在电路板。

因为由IC本身产生的热量,在以往的产品不能达到在于在许多应用中,包括办公设备用2.0A马达的驱动电流范围连续操作。这种新产品可以通过降低输出电阻同时驱动两个通道由50%削减发热* 1。

虽然在之前的产品IC的内部逻辑稳压电路是工作在待机,新产品能够在待机或者停止进行调压,由于睡眠功能的结合。因此,IC的功率消耗被降低。

此外,新的产品不仅驱动步进马达,它也提供接口用于驱动刷直流电机。这提供了步进电机的各种组合和有刷直流电机;例如步进电机中的一个信道和有刷直流电机的两个通道。通过加强其产品线,东芝提供了多种选择,以满足电机驱动应用的各种需求。

新产品的主要特点

发热低
发热2-频道同时驱动的由低降低电阻(0.6Ω或更小,上部+下部)。
低振动,低噪音
1/4步骤高分辨率电机驱动技术(最大值),衰减模式切换功能的恒流控制被采用,以减少振动和噪音。
低功耗
通过外部引脚控制内置的休眠功能减少了待机的IC电流消耗。
小包装
设备和模块的热处理可以通过采用一个小和高散热HTSSOP封装被简化。这可以向小型化集成电路和降低成本。东芝还计划推出采用QFN封装,这是一个更紧凑的封装。
建错误检测电路
新产品采用了热关断及过流关断电路。的安全性和设备的可靠性设备设计过程中增加了信号他们输出。
应用
工业设备(监控摄像头,银行终端,如ATM机,按职位和工厂自动化设备),娱乐设备(弹珠和视频老虎机),和家电(冰箱和空调)
