ASM161, ASM162  
mP Supervisory Circuit  
Description  
The ASM161 and ASM162 are cost effective, low power  
supervisory circuits that monitor power supplies in microprocessor,  
microcontroller and digital systems. If the power supply drops below  
the reset threshold level, a reset is asserted and remains asserted for at  
http://onsemi.com  
least 800 ms after V  
has risen above the reset threshold. An  
CC  
improved manual reset architecture gives the system designer  
additional flexibility.  
The debounced manual reset input is negative edge triggered. The  
reset pulse period generated by a MR transition is a minimum of  
800 ms and a maximum of 2 sec duration. In addition, The MR input  
signal is blocked for an additional 49 mS minimum after the reset pulse  
ends. During the MR disable period, the microcontroller is guaranteed  
a time period free of additional manual reset signals. During this  
period DRAM contents can be refreshed or other critical system tasks  
undertaken. Low power consumption makes the ASM161/162 ideal  
for use in portable and battery operated equipments. With 3 V  
supplies, power consumption is 8 mW typically and 30 mW maximum.  
The ASM161 has an opendrain, activeLOW RESET output and  
requires an external pullup resistor. The ASM162 has an active  
HIGH RESET output.  
The ASM161/162 are offered in compact 4pin SOT143 packages.  
No external components are required to trim threshold voltage for  
monitoring different supply voltages. With six different factory set,  
reset, threshold ranges from 2.63 V to 4.63 V, the ASM161/162 are  
suitable for monitoring 5 V, 3.6 V and 3.0 V supplies. The  
ASM161/162 are available in temperature ranges 0°C to 70°C and  
40°C to +85°C.
