FEATURES  
DESCRIPTION  
Qualified for Automotive Applications  
The TPS3808 microprocessor supervisory circuits  
monitor system voltages from 0.4 V to 5 V, 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 MR return  
above their thresholds.  
Power-On Reset Generator With Adjustable  
Delay Time: 1.25 ms to 10 s  
Very Low Quiescent Current: 2.4 μA Typ  
High Threshold Accuracy: 0.5% Typ  
Fixed Threshold Voltages for Standard Voltage  
Rails From 1.2 V to 5 V and Adjustable Voltage  
Down to 0.4 V Are Available  
The TPS3808 uses a precision reference to achieve  
0.5% threshold accuracy for VIT 3.3 V. The reset  
delay time can be set to 20 ms by disconnecting the  
CT pin, 300 ms by connecting the CT pin to VDD using  
a resistor, or can be user adjusted between 1.25 ms  
and 10 s by connecting the CT pin to an external  
capacitor. The TPS3808 has a very low typical  
quiescent current of 2.4 μA, so it is well suited to  
battery-powered applications. It is available in a small  
SOT-23 package and is fully specified over a  
temperature range of –40°C to 125°C (TJ).
