8. IC internal power dissipation calculation
Pd = (VCC × ICC) + (VM × IM) – (the power dissipated in the motor coils)
9. Techniques for measuring IC temperature increases
Since it is not possible to measure the IC chip temperature directly, use one of the following techniques.
• Thermocouple measurement
When measuring the IC temperature using a thermocouple, attach the thermocouple to the heat sink. While this
technique is simple, it suffers from large measurement errors when the thermal generation within the IC is not stable.
• Measurement using IC internal diode characteristics
We recommend using the parasitic diode between FG1 and ground to measure the operating temperature of this IC. To
measure the temperature, set FG1 to the high (off) state, measure the VF voltage of the parasitic diode, and calculate
the temperature from the temperature characteristics of the VF voltage.
According to Sanyo data: IF = –1 mA, and the VF temperature characteristics are about –2 mV/°C.
