ASM1834A/D  
Dual 5V and 3.3V μP Power Supply  
Supervisor with Manual Reset  
General Description  
Key Features  
The ASM1834 supervisors simultaneously monitor both  
3.3V and 5V power sources and generate reset signals  
when either supply is out of tolerance. When an out-of-  
tolerance condition is detected, the output-reset signal of  
the affected supply becomes active and resets the  
system microprocessor/microcontroller. On power-up and  
after the supply voltage returns to an in-tolerance  
condition, the reset signal remains active for pproximately  
350ms. This allows the power supply and system  
microprocessor to stabilize.  
Monitors 5V and 3.3V supplies simultaneously  
5V and 3.3V power-on reset  
350ms reset time  
Debounced pushbutton reset input  
Push-pull CMOS output  
ASM1834, ASM1834D  
Eliminates external pull-up resistors  
Active LOW (ASM1834), HIGH (ASM1834D)  
Open Drain Output  
ASM1834A  
Tolerance levels are independently selectable for both  
supplies. Tolerance options are 5% and 10% percent for  
the 5V supply and 10% and 20% percent for the 3.3V  
supply.  
Active LOW  
Selectable 5V and 3.3V trip point tolerance  
Internal power drawn from highest input voltage, 5V  
or 3.3V  
The ASM1834 and ASM1834D have push-pull reset  
output stages. The ASM1834A reset outputs are open  
drain devices that can both be connected to either 5V or  
3.3V supply. The ASM1834 and ASM1834A have active  
LOW reset outputs. The ASM1834D has active HIGH  
reset outputs.  
Precision temperature-compensated voltage  
reference and comparator  
Low cost surface mount SO, compact MicroSO and  
DIP packages.  
Wide operating temperature: -40°C to +85°C  
All devices can generate reset signals through an  
internally debounced pushbutton reset input that affects  
both reset outputs.  
Applications  
Microprocessors  
PDAs, Hand-held PCs  
Embedded Controllers  
Telecommunication Systems  
Power Supplies  
All devices operate over the extended industrial  
temperature range. Devices are available in 8-pin DIP,  
surface mount 8-pin SO and 8-Pin MicroSO packages.  
Die are also available.
