FUJITSU MICROELECTRONICS DATA SHEET DS04-27406-5Ea ASSP For Power Supply Applications BIPOLAR Power Voltage Monitoring IC with Watchdog Timer MB3793-30A • DESCRIPTION The MB3793 is an integrated circuit to monitor power voltage it incorporates a watchdog timer. A reset signal is output when the power is cut or falls abruptly. When the power recovers normally after resetting, a power-on reset signal is output to microprocessor units MPUs . An internal watchdog timer with two inputs for system operation diagnosis can provide a fall-safe function for various application systems. There is also a mask option that can detect voltages of V to V in 0.1-V steps. • FEATURES • Precise detection of power voltage fall ± • Detection voltage with hysteresis • Low power dispersion ICC = 31 µA reference • Internal dual-input watchdog timer • Watchdog-timer halt function by inhibition pin • Independently-set watchdog and reset times • Three types of packages SOP-8pin 2 types, SSOP-8pin 1 type • APPLICATION • Arcade Amusement etc. Copyright 2003-2008 FUJITSU MICROELECTRONICS LIMITED All rights reserved MB3793-30A • PIN ASSIGNMENTS TOP VIEW RESET 8 CK1 7 CK2 6 INH FPT-8P-M01 FPT-8P-M02 FPT-8P-M03 • PIN DESCRIPTION Pin no. 1 2 Symbol RESET CTP GND Descriptions Outputs reset pin Watchdog timer monitor time setting pin Power-on reset hold time setting pin Ground pin Pin no.
