●Cautions on use.
(1) Absolute maximum ratings
Use of the IC in excess of absolute maximum ratings such as the applied voltage or operating temperature range
may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open
mode) when such damage is suffered. A physical safety measure such as a fuse should be implemented when use
of the IC in aspecial mode where the absolute maximum ratings may be exceeded is anticipated.
(2) GND potential
Ensure a minimum GND pin potential in all operating conditions.
(3) Short circuit mode between terminals and wrong mounting
In order to mount the IC on a set PCB, pay thorough attention to the direction and offset of the ICs. Erroneous
mounting can destroy the IC. Furthermore, if a short circuit occurs due to foreign matters entering between
terminals or between the terminal and the power supply or the GND terminal, the IC can destroy.
(4) Actions in strong magnetic field
Use caution when using the IC in the presence of a strong magnetic field as doing so may cause the IC to
malfunction.
(5) Mutual impedance
Use short and wide wiring tracks for the power supply and ground to keep the mutual impedance as small as
possible .Use a capacitor to keep ripple to a minimum.
(6) About warm-up time
Operation depends on a power-supply voltage and an external constant for time until stabilizing. Please confirm
warm-up time enough when you use it.
