Device Overview
1-8C141-E057-01EN
(5) Power on/off sequence
The voltage detector circuits (the MHE Series and MHF Series) monitor +5 V.
The circuits do not allow a write signal if either voltage is abnormal. These
prevent data from being destroyed and eliminates the need to be concerned with
the power on/off sequence.
