Points to remember on handling of ICs
(1) Heat Radiation Design
In using an IC with large current flow such as power amp, regulator or driver, please design the device so that heat is appropriately
radiated, not to exceed the specified junction temperature (T
normal use. An inadequate IC heat radiation design can lead to decrease in IC life, deterioration of IC characteristics or IC breakdown.
In addition, please design the device taking into considerate the effect of IC heat radiation with peripheral components.
(2) Back-EMF
When a motor rotates in the reverse direction, stops or slows down abruptly, a current flow back to the motor’s power supply due to
the effect of back-EMF. If the current sink capability of the power supply is small, the device’s motor power supply and output pins
might be exposed to conditions beyond maximum ratings. To avoid this problem, take the effect of back-EMF into consideration in
system design.
