3 Description
The TPS3808E 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 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 is
available in the SOT-23-6 , and is fully specified over
a temperature range of –40°C to 125°C (TJ).
