GENERAL DESCRIPTION  
The ADM690A/ADM692A/ADM802L/M/ADM805L/M  
family of supervisory circuits offers complete single chip  
solutions for power supply monitoring and battery control  
functions in microprocessor systems. These functions include  
µP reset, backup battery switchover, watchdog timer, and power  
failure warning.  
The ADM805L/M provides an active high reset output, RESET  
instead of RESET.  
The family of products is fabricated using an advanced epitaxial  
CMOS process combining low power consumption and high  
reliability. RESET assertion is guaranteed with VCC as low as 1 V.  
They provide a pin-compatible upgrade for the MAX690A/  
MAX692A/MAX802L/MAX802M/MAX805L  
The ADM690A/ADM692A/ADM802L/M/ADM805L/M are  
available in 8-pin packages and provide:  
All parts are available in 8-pin DIP and SOIC packages. The  
ADM690A is also available in a new space-saving microSOIC  
package.  
1. Power-on reset output during power-up, power-down and  
brownout conditions. The RESET output remains opera-  
tional with VCC as low as 1 V.  
2. Battery backup switching for CMOS RAM, CMOS  
microprocessor or other low power devices.  
3. A reset pulse if the optional watchdog timer has not been  
toggled within 1.6 seconds.  
4. A 1.25 V threshold detector for power fail warning, low battery  
detection, or to monitor a power supply other than +5 V.  
On the ADM690A/ADM802L/ADM805L the reset voltage  
threshold is 4.65 V. On the ADM692A/ADM802M/  
ADM805M, the reset voltage threshold is 4.40 V.  
The ADM802L/ADM802M guarantee power fail accuracies to  
±2%.
