Description
General part information
TPS3808E-Q1 Series
The TPS3808E-Q1 family of microprocessor supervisory circuits monitors 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 manual reset (MR) return above the respective thresholds.
The TPS3808E-Q1 device uses a precision reference to achieve 0.5% threshold accuracy. 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 TPS3808E device has a very low typical quiescent current of 0.6 µA, and is designed for battery-powered applications. The TPS3808E-Q1 is available in the SOT-23-6 , and is fully specified over a temperature range of –40°C to 125°C (TJ).
