FEATURES
DESCRIPTION
Qualified for Automotive Applications
Power-On Reset Generator With Adjustable
The TPS3808 microprocessor supervisory circuits
monitor system voltages from 0.4 V to 5 V, asserting
Delay Time: 1.25 ms to 10 s
an open-drain RESET signal when the SENSE
Very Low Quiescent Current: 2.4 mA Typ
voltage drops below a preset threshold or when the
High Threshold Accuracy: 0.5% Typ
manual reset (MR) pin drops to a logic low. The
Fixed Threshold Voltages for Standard Voltage
RESET output remains low for the user-adjustable
delay time after the SENSE voltage and MR return
Rails From 1.2 V to 5 V and Adjustable Voltage
above their thresholds.
Down to 0.4 V Are Available
Manual Reset (MR) Input
The TPS3808 uses a precision reference to achieve
0.5% threshold accuracy for VIT ≤ 3.3 V. The reset
Open-Drain RESET Output
delay time can be set to 20 ms by disconnecting the
Temperature Range: –40°C to 125°C
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 mA, so it is well suited to
DSP or Microcontroller Applications
battery-powered applications. It is available in a small
Notebook/Desktop Computers
SOT-23 package and is fully specified over a
