MITSUBISHI <Dig./Ana. INTERFACE> AC-DC TOTAL SYSTEM RESET IC
DESCRIPTION
M5297P is a system reset IC designed for Power Supply PIN CONFIGURATION (TOP VIEW) System at office Automation, Factory Automation equip- ment, which watches both AC Power Supply and DC Power Vee LJ 14] ZacDL. Supply at the same time. Von [Zl fig) ZReL This IC watches the AC Power Supply, in shutting off the oO fi) Leo AC Power Supply, that is to say before dropping of the Vore [4 Hil cs System Power Supply (DC Power Supply), which detects the Vors [5] Fd c. abnormal state of the System. or a a * After the AC Power Supply shut off, in normal state of ac & the System Power Supply (DC Power Supply), this IC sends Ce [8] GNo the System Reset Output to the CPU and MPU. Continuieusly when the trouble of the System Power Supply (DC Power Outline 14P4 Supply) happen, users have alrkady been able to complete the all emergency measurment.
