The TLV1701-Q1 (Single), TLV1702-Q1 (Dual) and
1
•
•
Qualified for Automotive Applications
TLV1704-Q1 (Quad) devices offers a wide supply
range, rail-to-rail inputs, low quiescent current, and
low propagation delay. All these features come in
industry-standard, extremely-small packages, making
these devices the best general-purpose comparators
available.
AEC Q100-Qualified With the Following Results
–
–
–
–
Device Temperature Grade 1: –40°C to
+125°C Ambient Operating Temperature
Device HBM ESD Classification Level 2
(TLV1701-Q1)
The open collector output offers the advantage of
allowing the output to be pulled to any voltage rail up
to 36 V above the negative power supply, regardless
of the TLV170x-Q1 supply voltage.
Device HBM ESD Classification Level 1C
(TLV1702-Q1,TLV1704-Q1)
Device CDM ESD Classification Level C6
•
•
•
•
•
•
Supply Range: 2.2 V to 36 V or ±1.1 V to ±18 V
Low Quiescent Current: 55 µA per Comparator
Input Common-Mode Range Includes Both Rails
Low Propagation Delay: 560 ns
The device is a microPower comparator. Low input
offset voltage, low input bias currents, low supply
current, and open-collector configuration make the
TLV170x-Q1 device flexible enough to handle almost
any application, from simple voltage detection to
driving a single relay.
Low Input Offset Voltage: 300 µV
Open Collector Outputs:
The device is specified for operation across the
expanded industrial temperature range of –40°C to
+125°C.

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Input pins are diode-clamped to the power-supply rails. Input signals that can swing more than 0.5 V beyond the supply rails must be
current limited to 10 mA or less.

8 Detailed Description
8.1 Overview
The TLV170x-Q1 comparator features rail-to-rail input and output on supply voltages as high as 36 V. The rail-to-
rail input stage enables detection of signals close to the supply and ground. The open-collector configuration
allows the device to be used in wired-OR configurations, such as a window comparator. A low supply current of
55 μA per channel with small, space-saving packages, makes these comparators versatile for use in a wide
range of applications, from portable to industrial.

8.3 Feature Description
8.3.1 Comparator Inputs
The TLV170x-Q1 device is a rail-to-rail input comparator, with an input common-mode range that includes the
supply rails. The TLV170x-Q1 device is designed to prevent phase inversion when the input pins exceed the
supply voltage. Figure 18 shows the TLV170x-Q1 device response when input voltages exceed the supply,
resulting in no phase inversion.

9 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.
9.1 Application Information
The TLV170x-Q1 device can be used in a wide variety of applications, such as zero crossing detectors, window
comparators, over and undervoltage detectors, and high-side voltage sense circuits.
9.2 Typical Application
Comparators are used to differentiate between two different signal levels. For example, a comparator
differentiates between an overtemperature and normal-temperature condition. However, noise or signal variation
at the comparison threshold causes multiple transitions. This application example sets upper and lower
hysteresis thresholds to eliminate the multiple transitions caused by noise.

Typical Application (continued)
9.2.2 Detailed Design Procedure
Make a small change to the comparator circuit to add hysteresis. Hysteresis uses two different threshold voltages
to avoid the multiple transitions introduced in the previous circuit. The input signal must exceed the upper
threshold (VH) to transition low, or below the lower threshold (VL) to transition high.
Figure 20 illustrates hysteresis on a comparator. Resistor Rh sets the hysteresis level. An open-collector output
stage requires a pullup resistor (Rp). The pullup resistor creates a voltage divider at the comparator output that
introduces an error when the output is at logic high. This error can be minimized if Rh > 100 Rp.
When the output is at a logic high (5 V), Rh is in parallel with Rx (ignoring Rp). This configuration drives more
current into Ry, and raises the threshold voltage (VH) to 2.7 V. The input signal must drive above VH = 2.7 V to
cause the output to transition to logic low (0 V).
When the output is at logic low (0 V), Rh is in parallel with Ry. This configuration reduces the current into Ry, and
reduces the threshold voltage to 2.3 V. The input signal must drive below VL = 2.3 V to cause the output to
transition to logic high (5 V).
For more details on this design and other alternative devices that can be used in place of the TLV1702, refer to
Precision Design TIPD144, Comparator with Hysteresis Reference Design.
9.2.3 Application Curve
Figure 21 shows the upper and lower thresholds for hysteresis. The upper threshold is 2.76 V and the lower
threshold is 2.34 V, both of which are close to the design target.
Figure 21. TLV1701 Upper and Lower Threshold With Hysteresis
10 Power Supply Recommendations
The TLV170x-Q1 device is specified for operation from 2.2 V to 36 V (±1.1 to ±18 V); many specifications apply
from –40°C to +125°C. Parameters that can exhibit significant variance with regard to operating voltage or
temperature are presented in the Typical Characteristics section.
CAUTION
Supply voltages larger than 40 V can permanently damage the device; see the
Absolute Maximum Ratings.
Place 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high-
impedance power supplies. For more detailed information on bypass capacitor placement; see the Layout
Guidelines section.

11 Layout
11.1 Layout Guidelines
Comparators are very sensitive to input noise. For best results, maintain the following layout guidelines:
•
•
•
Use a printed-circuit board (PCB) with a good, unbroken low-inductance ground plane. Proper grounding (use
of ground plane) helps maintain specified performance of the TLV170x-Q1 device.
To minimize supply noise, place a decoupling capacitor (0.1-μF ceramic, surface-mount capacitor) as close
as possible to VS as shown in Figure 22.
On the inputs and the output, keep lead lengths as short as possible to avoid unwanted parasitic feedback
around the comparator. Keep inputs away from the output.
•
•
Solder the device directly to the PCB rather than using a socket.
For slow-moving input signals, take care to prevent parasitic feedback. A small capacitor (1000 pF or less)
placed between the inputs can help eliminate oscillations in the transition region. This capacitor causes some
degradation to propagation delay when the impedance is low. Run the topside ground plane between the
output and inputs.
•
Run the ground pin ground trace under the device up to the bypass capacitor, shielding the inputs from the
outputs.
