Data Sheet  
AS1904, AS1905, AS1906  
Ultra Low-Power µP Supervisory Circuit  
1 General Description  
The AS1904/5/6 family is an ultra low-power supervisory  
circuit device.  
2 Key Features  
 
Low 150nA (typical) Supply Current  
 
Precision Monitoring of 2.5-, 3-, and 3.3V-Power  
Supplies  
The device can be used to monitor the supply voltage of  
digital systems and microprocessors and initiate a reset  
when the voltage goes below a predefined threshold.  
The duration of the reset is 5/20/100/500ms (typ.) after  
the supply voltage has risen above the threshold.  
 
 
 
Supply Voltage Range 1.0 to 3.6V  
Reset Threshold Available from 2.2 to 3.1V  
Available in three Versions  
The device exhibits excellent reliability and can reduce  
application costs by eliminating all external components.  
- AS1904 Push-Pull RESETN  
- AS1905 Push-Pull RESET  
The device is available with different output drivers:  
- AS1906 Open Drain RESETN  
4 Time-Out Periods Ranging from 5 to 500ms  
 
 
 
The AS1904 has a push-pull driver with an active low  
reset.  
 
 
Detection Voltage Accuracy: 1.5%  
The AS1905 uses the same output stage as the  
AS1904, but has an active high reset.  
 
 
 
 
Temperature Range: -40 to +85°C  
SOT23-3 Package  
The AS1906 has an open drain output with active low  
reset.  
Pin Compatible to MAX6326/6327/6328  
All devices operate down to a voltage of 1V.  
Superior Upgrade to austriamicrosystems  
AS1901/2/3 Device Family  
The reset thresholds are factory-trimmable between  
2.2V and 3.08V in steps of approximately 100mV.  
Each device of the AS1904/5/6 family is offered with four  
time-out periods of 5/20/100/500ms.  
3 Applications  
The extremely low current consumption of only 150nA  
(typ) at 3.3V makes the device ideal for use in portable  
applications.  
 
 
 
 
Computers  
Intelligent Instruments  
Controllers  
All devices are available in a 3-pin SOT23 package.
