SBVS050F–MAY 2004–REVISED OCTOBER 2006  
Low Quiescent Current, Programmable-Delay  
Supervisory Circuit  
FEATURES  
DESCRIPTION  
•
Power-On Reset Generator with Adjustable  
Delay Time: 1.25ms to 10s  
The  
TPS3808xxx  
family  
of  
microprocessor  
supervisory circuits monitor system voltages from  
0.4V to 5.0V, asserting an open drain RESET signal  
when the SENSE voltage drops below a preset  
threshold or when the manual reset (MR) pin drops  
to a logic low. The RESET output remains low for the  
user adjustable delay time after the SENSE voltage  
and manual reset (MR) return above their thresholds.  
•
•
•
Very Low Quiescent Current: 2.4µA typ  
High Threshold Accuracy: 0.5% typ  
Fixed Threshold Voltages for Standard  
Voltage Rails from 0.9V to 5V and Adjustable  
Voltage Down to 0.4V Are Available  
•
•
•
•
Manual Reset (MR) Input  
The TPS3808 uses a precision reference to achieve  
0.5% threshold accuracy for VIT ≤ 3.3V. The reset  
delay time can be set to 20ms by disconnecting the  
CT pin, 300ms by connecting the CT pin to VDD using  
a resistor, or can be user-adjusted between 1.25ms  
and 10s by connecting the CT pin to an external  
capacitor. The TPS3808 has a very low typical  
quiescent current of 2.4µA so it is well-suited to  
battery-powered applications. It is available in a  
small SOT23 and an ultra-small 2mm × 2mm QFN  
PowerPAD™ package and is fully specified over a  
temperature range of –40°C to +125°C (TJ).
