Points to remember on handling of ICs
Over current Protection Circuit
Over current protection circuits (referred to as current limiter circuits) do not necessarily protect ICs under
all circumstances. If the Over current protection circuits operate against the over current, clear the over
current status immediately.
Depending on the method of use and usage conditions, such as exceeding absolute maximum ratings can
cause the over current protection circuit to not operate properly or IC breakdown before operation. In
addition, depending on the method of use and usage conditions, if over current continues to flow for a long
time after operation, the IC may generate heat resulting in breakdown.
Thermal Shutdown Circuit
Thermal shutdown circuits do not necessarily protect ICs under all circumstances. If the thermal shutdown
circuits operate against the over temperature, clear the heat generation status immediately.
Depending on the method of use and usage conditions, such as exceeding absolute maximum ratings can
cause the thermal shutdown circuit to not operate properly or IC breakdown before operation.
Heat Dissipation 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 dissipated, not to exceed the specified junction temperature (TJ) at any time or
under any condition. These ICs generate heat even during normal use. An inadequate IC heat dissipation
design can lead to 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 dissipation on peripheral
components..
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 your system design.
