Low Power, 5V µP Reset  
- Active LOW, Push-Pull Output  
General Description  
Key Features  
The ASM1810 is a voltage supervisor with low-power, 5V µP  
active LOW Reset, Push-Pull output. Maximum supply current  
over temperature is a low 20µA.  
Low Supply Current  
•20 µA maximum (5.5 V)  
Automatically restarts a microprocessor after power failure  
150ms reset delay after VCC returns to an in-tolerance con-  
The ASM1810 generates an active LOW reset signal whenever  
the monitored supply is out of tolerance. A precision reference  
and comparator circuit monitor power supply (VCC) level.  
dition  
Active LOW power-up reset  
Precision temperature-compensated voltage reference and  
comparator  
Tolerance level options are 5%, 10% and 15%. When an out-of-  
tolerance condition is detected, an internal power-fail signal is  
generated which forces an active LOW reset signal. After VCC  
Eliminates external components  
Low cost TO-92 and compact surface mount SOT-23 pack-  
age  
returns to an in-tolerance condition, the reset signal remains  
active for 150ms to allow the power supply and system  
microprocessor to stabilize.  
Push-Pull output for minimum current drain  
Operating temperature -40°C to +85°C  
Applications  
The ASM1810 is designed with a push-pull output stage and  
operates over the extended industrial temperature range.  
Devices are available in low cost TO-92 and compact surface  
mount SOT-23 packages.  
Set-top boxes  
Cellular phones  
PDAs  
Energy management systems  
Embedded control systems  
Printers  
Other low power products in this family include the ASM1811/  
12/15/16/17, ASM1233D and ASM1233M.
