ASM1816  
Low Power 3.3V/3.0V µP Reset, Active LOW, Open-Drain Output  
General Description  
Applications  
The ASM1816 is a voltage supervisory device with low-power,  
3.3V/3V µP Reset, active LOW, open-drain output. Maximum  
supply current over temperature is a low 15µA (at 3.6V).  
Set-top boxes  
Cellular phones  
PDAs  
Energy management systems  
Embedded control systems  
Printers  
The ASM1816 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.  
Single board computers  
Tolerance level options are 5%, 10%, 15% and 20%. When an  
out-of-tolerance condition is detected, an internal power-fail  
signal is generated which forces an active LOW reset signal.  
After VCC returns to an in-tolerance condition, the reset signal  
Typical Application  
VCC  
remains active for 150ms to allow the power supply and system  
microprocessor to stabilize.  
ASM1816  
The ASM1816 is designed with a open-drain output stage and  
operates over the extended industrial temperature range.  
Devices are available in TO-92 and compact surface mount  
SOT-23 packages.
