(1) Heat Radiation Design
(2) Back-EMF
Points to remember on handling of ICs
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
condition. These ICs generate heat even during 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.
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.
