User's Guide User's Manual RAGU V1.0 The RAGU is Evaluation Tool controls the stepping motor driver IC to demonstrate and evaluate its functions: 1. Speed control (by variable clock frequency) 2. Spin direction control (Clockwise or counter-clockwise) 3. Power Save 4. Excitation modes 5. Current decay control 6. Output current control 7. Junction temperature measurement (by TEST pin diode) 8. Efficiency measurement (Icc vs Iout) This system is composed of Software and Hardware parts. The Software runs in a PC with a USB port, and communicates with the hardware. The Hardware is composed of 2 major parts, RAGU main board (RAGU-main1-EVK-001) and RAGU option board (RAGU-op1-EVK-001). RAGU main board generates the signals to control the DUT (Device under test). RAGU option board allows oscilloscope feature and monitors output voltages and currents. (c) 2018 ROHM Co., Ltd. 1/14 No. 61UG032E Rev.001 Nov.2018 RAGU V1.0 User's Manual I.
