10. Measuring the IC’s temperature rise

• Thermocouple measurement

When using a thermocouple for temperature measurement, attach the thermocouple to a heat sink fin. This

temperature measurement technique is straightforward. However, a large measurement error occurs when the heat

generation is not in a steady state.

• Measurement using IC internal diode characteristics

We recommend using the parasitic diode that exists between LD and ground in this IC. Remove the external

resistor when measuring. (Sanyo data indicates that ILD = –1 mA, about –1.9 mV/°C, when the LD pin is high.)

11. Servo constants

The servo constant calculation varies significantly with the motor used, and requires specialized know-how. Thus

this should be handled by the motor manufacturer. Sanyo can provide the required IC characteristics data for servo

constant calculation, and the motor manufacture should provide the frequency characteristics simulation data for the

specified filter characteristics.
