2 Microstepping operation for High Precision, Quietness and Safety Contents Features of SNYO's Motor Driver Hybrid ICs (HICs) to Microstepping motor is widely used as a method that can realize highprecision positioning and quiet operation to minimize the impact on the ambient environment. SNYO motor driver hybrid ICs (HICs) can motor revolutions using only an externally input clock signal frequency. In addition, these HICs also incorporate a current detecting resistor, which helps to simplify the mechanical design. Models that incorporate various protective functions such as overcurrent, overheating and motor pin open have also been added to the lineup to enhance motor safety. We hope that you will consider SNYO motor driver HICs to further reduce the size and increase the safety of your electronic equipment.

3 Features of Motor Driver Hybrid ICs Features SNYO Motor Driver Hybrid ICs (HICs) are created using SNYO's unique insulated metal substrate technology (IMST TM ), which adopts the aluminum, a metal, as the base substrate material. This section provides a short introduction to the superlative features of IMST TM. Full complement of built-in protection functions Models that incorporate various protective functions such as overcurrent, overheating and motor pin open have also been added to the lineup to enhance motor safety. Features Superlative Heat Dissipation Heat is one of the points that determines the reliability of electronic equipment. The IMST TM substrate efficiently radiates heat that would otherwise concentrate in the device. This is the optimal mounting technology for the power electronics area. Copper Foil Melting Current Comparison Copper foil melting current () IMST TM substrate Film thickness μm μm PC Copper foile Copper foil width (mm) Copper foile width IMST TM substrate or printed board Film thickness 0μm μm μm IMST TM can handle about four times current that a printed board can.

Temperature sensor pplied power Chip resistor : Chip resistor CR IMST TM substrate or printed board ( mm) : Chip resistor CR (.. 0.mm) Reduced Design Periods No matter how far digital technology s, the current block will always remain analog. y adopting hybrid ICs which integrate both power s and the analog s that require both experience and know-how on the part of the designer, shortened design period and design simplification can be achieved. Reduced Number of Components The use of IMST TM hybrid ICs can reduce the total number of parts required in the end product and contribute to achieving end product miniaturization, a reduced number of steps in the assembly process, simplification of materials management, improved serviceability, and cost reductions. Low-profile, Thin-form and Hollow s wide variety of package line-up: low-profile type [H=.mm], slim type [t=.mm], and hollow type, for the board of the set on which the hybrid ICs are mounted. Comparison of (Concept Diagram) are Chip Mounting are semiconductor chips are mounted directly on the IMST TM substrate and devices are connected by ultrasonically bonded aluminum wire. This allows the number of solder connections to be reduced, thus increasing device and system uilt-in Current Detection Resistor With IMST TM boards, the ry required for detecting the currents of power devices, resistors, comparators and other such components can be mounted on the same boards. This results in high current accuracy and stable characteristics. Easy Rotational Control In the case of stepping motor drivers with built-in phase signal distribution ICs, the motor speed can be led simply by inputting clock signals so that it is easy to verify operation.
