ASM690A/692A  
ASM802L/802M  
ASM805L  
April 2008  
rev 1.7  
µP Power Supply Supervisor With Battery Backup Switch  
General Description  
• Short circuit protection and thermal limiting  
The ASM690A / ASM692A / ASM802L / ASM802M /  
ASM805L offers complete single chip solutions for power  
supply monitoring and control battery functions in  
microprocessor systems. Each device implements four  
functions: Reset control, watchdog monitoring, battery-  
backup switching and powerfailure monitoring. In addition  
to microprocessor reset under power-up and power-down  
conditions, these devices provide battery-backup  
switching to maintain control in power loss and brown-out  
situations. Additional monitoring capabilities can provide  
an early warning of unregulated power supply loss before  
the voltage regulator drops out. The important features of  
these four functions are:  
• Small 8-pin SO and 8-pin PDIP packages  
• No external components  
• Specified over full temperature range  
Applications  
• Embedded control systems  
• Portable/Battery operated systems  
• Intelligent instruments  
• Wireless instruments  
• Wireless communication systems  
• PDAs and hand-held equipments  
• µP / µC power supply monitoring  
• Safety system  
• 1.6 second watchdog timer to keep microprocessor  
responsive  
Typical Operating Circuit  
• 4.40V or 4.65V VCC threshold for microprocessor reset  
at power-up and power-down  
•
SPDT (Single-pole, Double-throw) PMOS switch  
connects backup power to RAM if VCC fails  
• 1.25V threshold detector for power loss or general  
purpose voltage monitoring  
These features are pin-compatible with the industry  
standard power-supply supervisors. Short-circuit and  
thermal protection have also been added. The ASM690A  
/ ASM802L / ASM805L generate a reset pulse when the  
supply voltage drops below 4.65V and the ASM692A /  
ASM802M generate a reset below 4.40V. The ASM802L /  
ASM802M have power-fail accuracy to ± 2%. The  
ASM805L is the same as the ASM690A except that  
RESET is provided instead of RESET.

Features  
• Two precision supply-voltage monitor options  
4.65V (ASM690A / ASM802L / ASM805L)  
4.40V (ASM692A / ASM802M )  
• Battery-backup power switch on-chip  
• Watchdog timer: 1.6 second timeout  
• Power failure / low battery detection
