The SP691A/693A/800L/800M offers complete µP monitoring and watchdog functions. The SP691A/693A/800L/800M is ideal for a low-cost battery management solution and is well suited for portable, battery-powered applications with its supply current of 35µA. The 6ns chip-enable propagation delay, the 25mA current output in battery-backup mode, and the 250mA current output in standard operation also makes the SP691A/693A/800L/800M suitable for larger scale, high-performance equipment. ■ Precision 4.65V/4.40V Voltage Monitoring ■ 200ms Or Adjustable Reset Time ■ 100ms, 1.6s Or Adjustable Watchdog Time ■ 60µA Maximum Operating Supply Current ■ 2.0µA Maximum Battery Backup Current ■ 0.1µA Maximum Battery Standby Current ■ Power Switching 250mA Output in Vcc Mode (0.6Ω) 25mA Output in Battery Mode (5Ω) ■ On-Board Gating of Chip-Enable Signals Memory Write-Cycle Completion 6ns CE Gate Propagation Delay ■ Voltage Monitor for Power-Fail or Low Battery ■ Backup-Battery Monitor ■ RESET Valid to Vcc=1V ■ 1% Accuracy Guaranteed (SP800L/800M) ■ Pin Compatible Upgrade to MAX691A/693A/ 800L/800M r e b m u N t r a P d l o h s e r h T T E S E R y c a r u c c A T E S E R y c a r u c c A I F P h c t i w S y r e t t a B - p u k c a B A 1 9 6 P S V 5 6 . 4 + V m 5 2 1 + % 4 S E Y A 3 9 6 P S V 0 4 . 4 + V m 5 2 1 + % 4 S E Y L 0 0 8 P S V 5 6 . 4 + V m 0 5 + % 1 S E Y M 0 0 8 P S V 0 4 . 4 + V m 0 5 + % 1 S E Y DESCRIPTION FEATURES VBATT VOUT Vcc GND BATT ON PFO PFI OSCIN RESET WDO CEIN CEOUT WDI LOWLINE 16 DIP/SO TOP VIEW 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 Corporation RESET OSCSEL Now Available in Lead Free Packaging ® |
