During power-on, RESET is asserted when the
supply voltage (VDD) becomes higher than 1.1 V.
Thereafter, the supervisory circuit monitors VDD and
keeps RESET active as long as VDD remains below
the threshold voltage VIT. An internal timer delays the
return of the output to the inactive state (low) to
ensure proper system reset. The delay time (td(typ) =
200 ms) starts after VDD has risen above the
threshold voltage, VIT. When the supply voltage drops
below the VIT threshold voltage, the output becomes
active (high) again. No external components are
required. All the devices in this family have a fixed
sense-threshold voltage (VIT) set by an internal
voltage divider.
The product spectrum is designed for supply voltages
of 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are
available in a 3-pin SOT-23 package. The TLV810
devices are characterized for operation over a
temperature range of –40°C to +125°C.

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.

APPLICATION INFORMATION
VDD TRANSIENT REJECTION
The TLV810 has built-in rejection of fast transients on the VDD pin. The rejection of transients depends on both
the duration and the amplitude of the transient. The amplitude of the transient is measured from the bottom of the
transient to the negative threshold voltage of the TLV810, as shown in Figure 7.
VDD
VITTransient
Amplitude
tw
Duration
Figure 7. Voltage Transient Measurement
The TLV810 does not respond to transients that are fast duration/low amplitude or long duration/small amplitude.
Figure 5 shows the relationship between the transient amplitude and the duration needed to trigger a reset. Any
combination of duration and amplitude above the curve generates a reset signal.
RESET DURING POWER UP/DOWN
The TLV810 output is valid when VDD is greater than 1.1 V. When VDD is less than 1.1 V, the output is undefined.
Figure 8 shows a typical waveform for the power-up sequence.

BIDIRECTIONAL RESET PINS
Some microcontrollers have bidirectional reset pins that act as both inputs and outputs. In a situation where both
the TLV810 and the microcontroller are attempting to drive the RESET line, a series resistor should be placed
between the output of the TLV810 and the RESET pin of the microcontroller to protect against excessive current
flow. Figure 9 shows the connection of the TLV810 to a microcontroller using a series resistor to drive a
bidirectional RESET line.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
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.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
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)
