Tps3808g01dbvr monitoring and reset chip IC is original and in stock
explain
Tps3808 series microprocessor monitoring circuit can monitor the system voltage from 0.4V to 5V, and set the open drain reset signal to effective when the sense voltage falls below the preset threshold or the manual reset (MR) pin falls to the logic low level. When the sense voltage and the return value of manual reset (MR) exceed the corresponding threshold, the reset output will remain low for the user adjustable delay time.
Tps3808 device uses precision voltage reference, which can achieve 0.5% threshold accuracy when Vit ≤ 3.3V. By disconnecting the CT pin, the reset delay time can be set to 20ms; The reset delay time can be set to 300ms by connecting the CT pin to the VDD with a resistor, or the user can adjust the reset delay time between 1.25ms and 10s by connecting the CT pin to an external capacitor. The tps3808 device has an ultra-low typical quiescent current of 2.4 μ A. Therefore, it is very suitable for battery powered applications. It adopts SOT-23 and 2mm × 2mm WSON package, rated operating temperature range – 40 ° C to 125 ° C (TJ)
