TLV7081
ZHCSIE1A –MAY 2018–REVISED JUNE 2018

7 Detailed Description
7.1 Overview
The TLV7081 is a single-channel, nano-power comparator that does not need a dedicated power supply
connection, and can operate down to 1.7 V. The comparator is available in an ultra-small, WCSP package
measuring 0.7 mm × 0.7 mm, making the TLV7081 applicable for space-critical designs like smartphones and
other portable or battery-powered applications.
The TLV7081 features a wide input-voltage range that is independent of supply voltage. Having an input range
that is independent of supply voltage allows the TLV7081 to be directly connected to sources that are active
even if the TLV7081 is not powered.
The TLV7081 has an open-drain output stage that can be pulled beyond V+, making it appropriate for level
translators and bipolar to single-ended converters.

7.3 Feature Description
The TLV7081 is a single-channel, nano-power comparator that operates down to 1.7 V. The inverting input is
internally tied to V+ which helps to streamline applications which use supply as the reference. The non-inverting
input IN extends to 5.6 V which is independent of the power supply V+ (1.7 V - 5.5 V) and it's available in an
ultra-small, WCSP package measuring 0.7 mm × 0.7 mm.
7.4 Device Functional Modes
The TLV7081 has a power-on-reset (POR) circuit. While the power supply (VS) is greater than VPOR (typically 1V)
and less than the minimum operating supply voltage, either upon ramp-up or ramp-down, the POR circuitry is
activated.
The POR circuit keeps the output high impedance (logical high) while activated.
When the supply voltage is greater than, or equal to, the minimum supply voltage, the comparator output reflects
the state of the input IN.

TLV7081

ZHCSIE1A –MAY 2018–REVISED JUNE 2018
Device Functional Modes (continued)
7.4.1 Inputs
The TLV7081 input extends from V- to 5.6 V which is independent of supply. The input IN can be any voltage
within these limits and no phase inversion of the comparator output occurs.
The input of TLV7081 is fault tolerant. It maintains the same high input impedance when V+ is unpowered or
ramping up. The input can be safely driven up to the specified maximum voltage (5.6 V) with V+ = 0 V or any
value up to the maximum specified.
The input bias current is typically 3 pA for input IN voltages between 0 and 5.6 V. The comparator inputs are
protected from undervoltage by internal diodes connected to V-. As the input voltage goes under V-, the
protection diodes become forward biased and begin to conduct causing the input bias current to increase
exponentially. Input bias current typically doubles for every 10°C temperature increase.
7.4.2 Internal Hysteresis
The device hysteresis transfer curve is shown in Figure 20. This curve is a function of three components: VTH
,
VOS, and VHYST
:
•
•
VTH is the actual set voltage or threshold trip voltage.
VOS is the internal offset voltage between IN and V+. This voltage is added to VTH to form the actual trip point
at which the comparator must respond to change output states.
•
VHYST is the internal hysteresis (or trip window) that is designed to reduce comparator sensitivity to noise
(10 mV typical).
VTH + VOS - (VHYST / 2)
VTH + VOS
VTH + VOS + (VHYST / 2)
Figure 20. Hysteresis Transfer Curve
7.4.3 Output
The TLV7081 features an open-drain output stage enabling the output logic levels to be pulled up to an external
source up to 5.5 V independently of the supply voltage.

8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The TLV7081 is a 4-pin, nano-power comparator with open-drain output that is well suited for monitoring battery
voltages. The TLV7081's benefits include a small package footprint and a unique input stage that allows the
comparator input to be driven by a voltage source even when the operating voltage for the comparator is turned-
off (zero volts).
8.2 Typical Applications
8.2.1 Nano-Power Battery Monitor

8.2.1.1 Design Requirements
For this design, follow these design requirements:
•
•
•
The supply voltage connected to pin (V+) serves as the reference voltage for the comparator and can be any
voltage between 1.7 V and 5.5 V.
The voltage applied to the input pin (IN) can be any voltage in the range of 0 V to 5.6 V. This voltage range is
uniquely independent of the supply voltage applied to pin (V+).
The comparator output pin (OUT) requires a pull-up resistor that sets the output-high logic level (VOH) for the
comparator. VPULL-UP should be connected to the supply voltage of the microcontroller which is monitoring the
comparator output and serves as the level-shifting block for the logic levels in the application.

Typical Applications (continued)
8.2.1.2 Detailed Design Procedure
Instead of being powered directly from the battery, the TLV7081 is powered directly from a voltage reference that
exists in the system. The input to the comparator (IN) is allowed to operate above and below the reference
voltage due to the unique analog front end of the TLV7081. When the battery voltage is above the reference
threshold, the output of the comparator is high and when the battery drops below the threshold of the reference,
the output of the comparator goes low (see Figure 22 for details). For simplicity, the integrated hysteresis of the
comparator is not shown in the timing diagram. Integrated hysteresis is helpful in avoiding glitches at the
comparator output when operating in noisy environments or when the input voltage changes thresholds very
slowly. An open-drain output configuration allows the output logic level of the comparator to be level-shifted to
match the logic level of the receiving device.
8.2.1.3 Application Curve
When the voltage applied to the input pin (IN) falls below the reference threshold (REF), the output pin (OUT) is
pulled low to ground (V-). Moreover, when the input voltage rises above REF, the output of the comparator goes
into a high impedance state and the OUT pin is pulled high by the pull-up resistor and VPULL-UP supply voltage.

8.2.2 Battery Monitoring in Portable Electronics
A recommended circuit diagram for monitoring a battery voltage in a personal electronic device is shown in
Figure 23. In this diagram, the GPIO pin of an application specific integrated circuit (ASIC) serves as the supply
voltage and the voltage reference for the TLV7081. Using a GPIO pin to power the TLV7081 is possible because
of the low quiescent current of the TLV7081. In systems where power consumption needs to be further reduced,
the GPIO pin can be used to power-cycle the TLV7081.

9 Layout
9.1 Layout Guidelines
A power supply bypass capacitor of 100 nF is recommended when supply output impedance is high, supply
traces are long, or when excessive noise is expected on the supply lines. Bypass capacitors are also
recommended when the comparator output drives a long trace or is required to drive a capacitive load. Due to
the fast rising and falling edge rates and high-output sink and source capability of the TLV7081 output stages,
higher than normal quiescent current can be drawn from the power supply. Under this circumstance, the system
would benefit from a bypass capacitor across the supply pins.

10.5 Electrostatic Discharge Caution
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.
