... MOSFETs in the output stage and a built-in phase signal distribution IC. The incorporation of a phase distribution IC allows the STK672-110-E to control the speed of the motor based on the frequency of an external input clock signal. It supports two types of excitation for motor control: 2-phase excitation and 1-2 phase excitation. It also provides a function for switching the motor direction ...

... The following circuit (for a lowered current of over 0.2A) is recommended if the application needs to temporarily lower the motor current. Here, a value of close to 100kΩ must be used for resistor RO1 to make the transistor output saturation voltage as low as possible. 5V RO1 Vref RO3 RO2 STK672-110-E STK672-110-E 10μF 10 Two-phase stepping motor + ...

... Thermal design [Operating range in which a heat sink is not used] The STK672-110-E package has a structure that uses no screws, and is recommended for use without a heat sink. This section discusses the safe operating range when no heat sink is used. In the maximum ratings specifications, Tc max is specified to be 105°C, and when mounted in an actual end product system, the Tc max value must never be exceeded during operation. Tc can be expressed by formula (A) below, and thus the range for Δ ...
