DESCRIPTION
Power-On Reset Generator with Adjustable
Delay Time: 1.25ms to 10s
Very Low Quiescent Current: 2.4µA typ
High Threshold Accuracy: 0.5% typ
Fixed Threshold Voltages for Standard
Voltage Rails from 0.9V to 5V and Adjustable
Voltage Down to 0.4V Are Available
Manual Reset (MR) Input
Open-Drain RESET Output
Temperature Range: –40°C to +125°C
Small SOT23 and 2mm × 2mm QFN Packages
The
TPS3808xxx
family
of
microprocessor
supervisory circuits monitor system voltages from
0.4V to 5.0V, 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 their thresholds.
The TPS3808 uses a precision reference to achieve
0.5% threshold accuracy for VIT ≤ 3.3V. The reset
delay time can be set to 20ms by disconnecting the
CT pin, 300ms by connecting the CT pin to VDD using
a resistor, or can be user-adjusted between 1.25ms
and 10s by connecting the CT pin to an external
capacitor. The TPS3808 has a very low typical
quiescent current of 2.4µA so it is well-suited to
battery-powered applications. It is available in a small
SOT23 and an ultra-small 2mm × 2mm QFN
PowerPAD™ package and is fully specified over a
temperature range of –40°C to +125°C (TJ).

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated
circuits be handled with appropriate precautions. Failure to observe proper handling and installation
procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision
integrated circuits may be more susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.

RESET
1
RESET is an open drain output that is driven to a low impedance state when RESET is asserted (either the
SENSE input is lower than the threshold voltage (VIT) or the MR pin is set to a logic low). RESET will remain
low (asserted) for the reset period after both SENSE is above VIT and MR is set to a logic high. A pull-up
resistor from 10kΩ to 1MΩ should be used on this pin, and allows the reset pin to attain voltages higher than
VDD.

MR

Driving the manual reset pin (MR) low asserts RESET. MR is internally tied to VDD by a 90kΩ pull-up
resistor.

4
Reset period programming pin. Connecting this pin to VDD through a 40kΩ to 200kΩ resistor or leaving it
open results in fixed delay times (see Electrical Characteristics). Connecting this pin to a ground referenced
capacitor ≥ 100pF gives a user-programmable delay time. See Selecting The Reset Delay Time in the
Device Operation section for more information.

This pin is connected to the voltage to be monitored. If the voltage at this terminal drops below the threshold
voltage VIT, then RESET is asserted.

DEVICE OPERATION
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 thresholds. A broad range of voltage
threshold and reset delay time adjustments are
available, allowing these devices to be used in a wide
array of applications. Reset threshold voltages can be
factory-set from 0.82V to 3.3V or from 4.4V to 5.0V,
while the TPS3808G01 can be set to any voltage
above 0.405V using an external resistor divider. Two
preset delay times are also user-selectable:
connecting the CT pin to VDD results in a 300ms reset
delay, while leaving the CT pin open yields a 20ms
reset delay. In addition, connecting a capacitor
between CT and GND allows the designer to select
any reset delay period from 1.25ms to 10s.
supply line can be used to allow the reset signal for
the microprocessor to have a voltage higher than VDD
(up to 6.5V). The pull-up resistor should be no
smaller than 10kΩ as a result of the finite impedance
of the RESET line.
SENSE INPUT
The SENSE input provides a terminal 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 1nF to 10nF
bypass capacitor on the SENSE input to reduce
sensitivity to transients and layout parasitics.
The TPS3808G01 can be used to monitor any
voltage rail down to 0.405V using the circuit shown in
Figure 11.
VIN
RESET OUTPUT
A typical application of the TPS3808G25 used with
the OMAP1510 processor is shown in Figure 10. The
open drain RESET output is typically connected to
the RESET input of a microprocessor. A pull-up
resistor must be used to hold this line high when
RESET is not asserted. The RESET output is
undefined for voltage below 0.8V, but this is normally
not a problem since most microprocessors do not
function below this voltage. RESET remains high
(unasserted) as long as SENSE is above its threshold
(VIT) and the manual reset (MR) is logic high. If either
SENSE falls below VIT or MR is driven low, RESET is
asserted, driving the RESET pin to a low impedance.

Figure 10. Typical Application of the TPS3808
with an OMAP Processor
Once MR is again logic high and SENSE is above VIT
+ VHYS (the threshold hysteresis), a delay circuit is
enabled which holds RESET low for a specified reset
delay period. Once the reset delay has expired, the
RESET pin goes to a high impedance state. The
pull-up resistor from the open drain RESET to the
8
The manual reset (MR) input allows a processor or
other logic circuits to initiate a reset. A logic low
(0.3VDD) on MR causes RESET to assert. After MR
returns to a logic high and SENSE is above its reset
threshold, RESET is de-asserted after the user
defined reset delay expires. Note that MR is internally
tied to VDD using a 90kΩ resistor so this pin can be
left unconnected if MR will not be used.
See Figure 12 for how MR can be used to monitor
multiple system voltages. Note that if the logic signal
driving MR does not go fully to VDD, there will be
some additional current draw into VDD as a result of
the internal pull-up resistor on MR. To minimize
current draw, a logic-level FET can be used as
illustrated in Figure 13.

The capacitor CT should be ≥ 100pF nominal value in
order for the TPS3808xxx to recognize that the

equation:

The reset delay time is determined by the time it
takes an on-chip precision 220nA current source to
charge the external capacitor to 1.23V. When a
RESET is asserted the capacitor is discharged. When
the RESET conditions are cleared, the internal
current source is enabled and begins to charge the
external capacitor. When the voltage on this capacitor
reaches 1.23V, RESET is de-asserted. Note that a
low leakage type capacitor such as a ceramic should
be used, and that stray capacitance around this pin
may cause errors in the reset delay time.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.
