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 Veo [1] 14] Eacpu Supply at the same time. Vor 21 fia) REL This IC watches the AC Power Supply, in shutting off the a z [deeo AC Power Supply, that is to say before dropping of the Vout] 8 filles System Power Supply (OC Power Supply), which detects the y 3 ge abnormal state of the System. me * After the AC Power Supply shut off, in normal state of ac [6 [9] cs 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.
