1 / 16 page SP703/704DS/07 SP703/704 Low Power Microprocessor Supervisory © Copyright 2000 Sipex Corporation 1 SP703/SP704 Low Power Microprocessor Supervisory with Battery Switch-Over The SP703/704 devices are microprocessor ( µP) supervisory circuits that integrate a myriad of components involved in discrete solutions to monitor power-supply and battery-control functions in µP and digital systems. The series will significantly improve system reliability and operational efficiency when compared to discrete solutions. The features of the SP703/704 devices include a manual reset input, a µP reset and backup-battery switchover, and power- failure warning. The series is ideal for applications in computers, controllers, intelligent instruments and automotive systems. All designs where it is critical to monitor the power supply to the µP and its related digital components will find the series to be an ideal solution. s Precision Voltage Monitor: SP703 at 4.65V SP704 at 4.40V s Reset Time Delay - 200ms s Debounced TTL/CMOS - Compatible Manual - Reset Input s Minimum component count s 60 µA Maximum Operating Supply Current s 0.6 µA Maximum Battery Backup Current s 0.1 µA Maximum Battery Standby Current s Power Switching 250mA Output in V CC Mode (0.6Ω) 25mA Output in Battery Mode (5 Ω) s Voltage Monitor for Power Fail or Low Battery Warning s Available in 8 pin SO and DIP packages s RESET asserted down to V CC = 1V s Pin Compatible Upgrades to MAX703/MAX704 DESCRIPTION PINOUT VOUT VCC GND PFI VBATT RESET MR PFO 1 2 3 4 5 6 7 8 INTERNAL BLOCK DIAGRAM 1.25V 1.25V BATTERY SWITCHOVER CIRCUITRY PFI MR VCC VBATT RESET GENERATOR VOUT RESET PFO ® |
