General Description  
Features  
The AAT351x PowerManager products are mem-  
bers of AnalogicTech's Total Power Management

microprocessor reset circuits provides the ultimate  
in versatility, allowing system designers full cus-  
tomization of the µP monitor and reset function  
without any additional components. The AAT351x  
family offers several combinations of threshold  
voltage, watchdog timeout period, reset active peri-  
od, and output drive configurations, which are all  
factory-programmed options. All devices are avail-  
able in 32 reset threshold voltages from 2.6V up to  
5V, with three watchdog timeout periods from  
6.3ms to 1600ms and three reset timeouts from  
1ms up to 140ms. Available output configurations  
are active low push-pull, active low open drain,  
active low bi-directional, and active high push-pull.  
Tight Voltage Tolerance: ±1.5%  
Low Quiescent Current: 5µA  
Guaranteed Reset Valid Down to 1V  
32 Voltage Options from 2.6V to 5.0V  
Three Reset Active Period Options:  
— 1ms, 20ms, 140ms  
Three Watchdog Timeout Period Options:  
— 6.3ms, 102ms, 1600ms  
Four Output Options:  
— Open Drain  
— Inverting  
— Non-Inverting  
— Bi-Directional  
Low Temperature Coefficient: 100ppm/°C  
5-Pin SOT23 Package
