SAM2系列产品是将输出开关元件、预驱动器、带限流电阻的自举二极管以及温度检测用热敏电阻集成在一个封装的三相无刷电机用驱动器。由于驱动IC的小型化以及采用功率芯片的高密度安装技术，保持内置器件同以往产品不变的前提下，产品封装尺寸减少了20%以上。
并且，实现了高温度检测精度和低噪声。该产品不仅仅可实现基板面积的小型化、高可靠性，还可以使高压电路的设计简易化。
SAM2 Series: Small-sized, High-voltage, 3-phase Motor Drivers
The SAM2 series, our latest 3-phase brushless motor drivers, supports voltages up to 1200 V and currents up to 50 A. All the devices required for controlling a 3-phase motor are integrated in its package.
Through the driver IC downsizing and high-density power chip mounting technologies, we succeeded in reducing the package size by ≥20% (compared to our old type ICs) with the same conventional devices included inside.
Moreover, the SAM2 series offers the industry-leading* temperature-sensing accuracy and low-noise characteristics. Your application will have a smaller PCB space, higher reliability, and more ease of designing high-voltage circuits.
So, this series is ideal for high-voltage, high-current applications such as an air-conditioning system intended for automotive and industrial use alike.

All-in-One and Compact
Schematic View: DBC Structure
Package Size Reduced by ≥20%
The SAM2 series employs the DBC (Direct Bonding Copper) structure in which components like a chip can be placed directly on a substrate.
With this new structure, we achieved to put together not only a power chip but also a temperature-sensing thermistor compactly inside.
We also successfully reduced the package size by ≥20% compared to our old type ICs, while not changing the devices to be included inside but changing the MIC size in the driver part.
Although the package is downsized, this series still ensures reliability because of its sufficient insulation distances, including clearance and creepage.
For automotive use, we emphasized the ‘design for safety’ and placed the VCC, OCP, and GND pins not to be adjacent.
For industrial use, we considered the ‘design for replaceability’ and came up with the pin configuration compatible with products from other manufacturers.
In addition, the SAM2 series comes in two different lengths of external pins to meet diverse scenarios and needs that your application may face.
Industry’s Highest* Temperature-sensing Accuracy
In the SAM2 series, the temperature-sensing thermistor is placed on the same DBC substrate as the power chip, not on the lead frame.
This helps your application have the industry’s highest temperature-sensing accuracy and the followability to a rapid temperature change.
Its high sensitivity to an abnormal temperature in the driving elements also allows your application to have a wider range of actual operating temperatures and better motor system quality.
Industry’s Lowest* Noise Characteristics
We developed and built our own freewheeling diodes, whose soft recovery characteristics are outstanding, into this series.
And this approach turned out to be very effective for suppressing noise at turn-on and for reducing emission noise as well or better than competitors.
You can also design your application with fewer filter circuits.
