Use of the IC in excess of absolute maximum ratings, such as the applied voltage or operating temperature range (Topr),
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 using the IC at
times where the absolute maximum ratings may be exceeded.
Ensure a minimum GND pin potential in all operating conditions. Make sure that no pins are at a voltage below the GND
at any time, regardless of whether it is a transient signal or not.
Perform thermal design, in which there are adequate margins, by taking into account the permissible dissipation (Pd) in
actual states of use.
Numbers and data in entries are representative design values and are not guaranteed values of the items.
Although ROHM is confident that the example application circuit reflects the best possible recommendations, be sure to
verify circuit characteristics for your particular application. Modification of constants for other externally connected
circuits may cause variations in both static and transient characteristics for external components as well as this Rohm IC.
Allow for sufficient margins when determining circuit constants.
