8 Detailed Description
8.1 Overview
The TPS3808 microprocessor supervisory product family is designed to assert a RESET signal when either the
SENSE pin voltage drops below VIT or the manual reset (MR) is driven low. The RESET output remains asserted
for a user-adjustable time after both the manual reset (MR) and SENSE voltages return above their respective
thresholds.

8.3 Feature Description
A broad range of voltage threshold and reset delay time adjustments are available for the TPS3808 device,
allowing these devices to be used in a wide array of applications. Reset threshold voltages can be factory-set
from 0.82 V to 3.3 V or from 4.4 V to 5 V, while the TPS3808G01 can be set to any voltage above 0.405 V using
an external resistor divider. Two preset delay times are also user-selectable: connecting the CT pin to VDD results
in a 300-ms reset delay, whereas leaving the CT pin open yields a 20-ms reset delay. In addition, connecting a
capacitor between CT and GND allows the designer to select any reset delay period from 1.25 ms to 10 s.
8.3.1 SENSE Input
The SENSE input provides a pin at which any system voltage can be monitored. If the voltage on this pin drops
below VIT, then RESET is asserted. The comparator has a built-in hysteresis to ensure smooth RESET
assertions and de-assertions. It is good analog design practice to put a 1-nF to 10-nF bypass capacitor on the
SENSE input to reduce sensitivity to transients and layout parasitics.
The TPS3808 device is relatively immune to short negative transients on the SENSE pin. Sensitivity to transients
is dependent on threshold overdrive, as shown in (Figure 5).
The TPS3808G01 can be used to monitor any voltage rail down to 0.405 V using the circuit shown in Figure 9.
