19-0366; Rev 5; 2/07 3.0V/3.3V Adjustable Microprocessor Supervisory Circuits MAX793/MAX794/MAX795 _______________General Description ____________________________Features The MAX793/MAX794/MAX795 microprocessor (µP) MAX793/MAX794/MAX795 supervisory circuits monitor and control the activities of Precision Supply-Voltage Monitor: +3.0V/+3.3V µPs by providing backup-battery switchover, Fixed Reset Trip Voltage (MAX793/MAX795) among other features such as low-line indication, µP Adjustable Reset Trip Voltage (MAX794) reset, write protection for CMOS RAM, and a watchdog Guaranteed Reset Assertion to VCC = 1V (see the Selector Guide below). The backup-battery volt- Backup-Battery Power Switching--Battery age can exceed VCC, permitting the use of 3.6V lithium Voltage Can Exceed VCC batteries in systems using 3.0V to 3.3V for VCC. On-Board Gating of Chip-Enable Signals--7ns The MAX793/MAX795 offer a choice of reset threshold Max Propagation Delay voltage range (denoted by suffix letter): 3.00V to 3.15V MAX793/MAX794 Only (T), 2.85V to 3.00V (S), and 2.55V to 2.70V (R). The Battery Freshness Seal MAX794 s reset threshold is set externally with a resistordivider. The MAX793/MAX794 are available in 16-pin Battery OK Output (MAX793) DIP and narrow SO packages, and the MAX795 comes Uncommitted Voltage Monitor for Power-Fail or in 8-pin DIP and SO packages. Low-Battery Warning Independent Watchdog Timer (1.6s timeout) Manual Reset Input _____________________Selector Guide Ordering Information FEATURE MAX793 MAX794 MAX795 PIN- PKG PART* TEMP RANGE Active-Low Reset PACKAGE CODE Active-High Reset MAX793_CPE
