Features, Applications

Low Power Microprocessor Supervisory with Battery Switch-Over

s Precision Voltage Monitor: 4.40V s Reset Time Delay 200ms s Watchdog Timer - 1.6 sec timeout s Minimum component count s 60μA Maximum Operating Supply Current s 0.6μA Maximum Battery Backup Current s 0.1μA Maximum Battery Standby Current s Power Switching 250mA Output in VCC Mode (0.6) 25mA Output in Battery Mode (5) s Voltage Monitor for Power Fail or Low Battery Warning s Available in 8 pin SO and DIP packages s RESET asserted down to VCC 1V s Pin Compatible Upgrades to MAX690A/692A/802L/802M/805L DESCRIPTION The SP690A/692A/802L/802M/805L/805M are a family of microprocessor (μP) supervisory circuits that integrate a myriad of components involved in discrete solutions to monitor powersupply 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 SP690A/692A/802L/802M/805L/805M include a watchdog timer, a μP reset and backup-battery switchover, and power-failure warning, a complete μP monitoring and watchdog solution. The series is ideal for applications in automotive systems, computers, controllers, and intelligent instruments. All designs where it is critical to monitor the power supply to the μP and it's related digital components will find the series be an ideal solution.

PARAMETERS Reset Threshold Hysteresis Reset Pulse Width, tRS RESET Output Voltage, NOTE 5

Watchdog Timeout, tWD WDI Pulse Width, tWP WDI Input Threshold, VCC = 5V, NOTE 4 WDI Input Current

NOTE 1: The input voltage limits on PFI (pin 4) and WDI (pin 6) may be exceeded if the current into these pins is limited to less than 10 mA. NOTE 2: Either VCC or VBATT can 0V if the other is greater than 2.0V. NOTE 3: equals the battery-charging current, equals the battery-discharging current. NOTE 4: WDI is guaranteed in an intermediate, non-logic level state if WDI is floating and VCC is in the operating voltage range. WDI is internally biased 35% of VCC with an input impedance of 50K. NOTE SP692A, SP802L, and SP802M only. NOTE 6: SP805L and SP805M only.
