P = P2 = 0.19 W
At start time:
P = P1 + P3 + P4 + P5 = 6.51 W
(for an output on duty of 100%)
16.Techniques for measuring the IC temperature increase
Measurement with a thermocouple
When using a thermocouple to measure the IC temperature, the thermocouple should be attached to a fin. While
this measurement technique is simple, it is subject to large measurement errors if the IC is not in a stable heat
generation state.
Measurement using the characteristics of an IC internal diode
We recommend using the parasitic diode between INT.IN and GND internal to the IC. (According to our data, I
D
= 1 mA with about
1.8 mV/°C) Remove the external resistor when making the measurements.
17.Servo constants
When calculating the servo constants, they will be heavily dependent on the motor actually used. Since experience is
generally required, these constants should be determined by the motor manufacturer. We can provide the IC
characteristics data required for the servo constants calculations as well as frequency characteristics simulation data
for the filter constants set by the motor manufacturer.
If the resistor connected between DOUT and INT.IN (R10) is too small, C8 and C9 are too large, and R10 is too
large, speed errors will be likely to occur due to the speed discriminator cutoff current and the integrator input
current. Therefore, a 10 to 100 k
resistor should be used. If the resistor connected between POUT and INT.IN (R8)
is too small, the PLL system influence will become too large and the in-phase pull-in to locking will get worse.
Therefore, do not make this value too small. (We recommend 1 M
when R10 is 75 k
.) First set the constants just
for the speed discriminator system (R9, R10, C8 and C9) and then set the R8 value for the PLL system.
