(2) When the output off time is set long
If the output off time is set to a very long length of time, the average current decreases, with the result that the torque at
motor start-up drops. Depending on the type of motor, it may be impossible to shift from the current limiter operation
state to the normal rotation state.
8.
Calculation of the IC’s internal power dissipation
Pd=(VCC × ICC)+(VM × IM) – (power dissipated by the motor coil)
9.
Measuring the increase in the IC’s temperature
Because the temperature of the IC chip cannot be measured directly, the temperature is normally measured using one of the
following methods.
9-1. Measurement using a thermocouple
In order to measure the temperature by using a thermocouple, mount the thermocouple on the fin. Although this method of
measurement is simple, if the rate of heat generation has not stabilized, the measurement error is great.
9-2. Measurement using the characteristics of a diode within the IC
It is recommended that the parasitic diode between FG1 and GND be used to measure the temperature of the IC.
Set FG1 high (the ‘‘off’’ state), measure the parasitic diode voltage VF, and calculate the temperature based on the
temperature characteristics of the voltage VF.
(Sanyo’s data: IF =–1mA, VF temperature characteristics: approximately –2 mV/ °C)
