Points to remember on handling of ICs
(1) Heat Radiation Design
In using an IC with large current flow such as a power amp, regulator or driver, please design the
device so that heat is appropriately radiated, so as not to exceed the specified junction temperature
(TJ) at any time and condition. These ICs generate heat even during normal use. An inadequate IC
heat radiation design can lead to a decrease in IC life, deterioration of IC characteristics or IC
breakdown. In addition, please design the device taking into consideration the effect of IC heat
radiation on peripheral components.
(2) Back-EMF
When a motor rotates in the reverse direction, stops or slows down abruptly, a current flows 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.
