7 Detailed Description
7.1 Overview
The TL331-Q1 is a single comparator with the ability to operate up to 36 V on the supply pin. This standard
device has proven ubiquity and versatility across a wide range of applications. This is due to its very wide supply
voltages range (2 V to 36 V), low Iq, and fast response.
The open-collector output allows the user to configure the output's logic low voltage (VOL) and can be utilized to
enable the comparator to be used in AND functionality.
The TL331B-Q1 and TL391B-Q1 are performance upgrades to industry standard TL331-Q1 using the latest
semiconductor process technologies that allows for lower offset voltages, lower input bias and supply currents
and faster response times. The TL331B can drop-in replace the "I" or "Q" versions of TL331-Q1. The TL391B-
Q1 is an alternate pinout of the TL331B-Q1 for replacing competitive devices.

7.3 Feature Description
The TL331-Q1 consists of a PNP Darlington pair input, allowing the device to operate with very high gain and
fast response with minimal input bias current. The input Darlington pair creates a limit on the input common
mode voltage capability, allowing TL331-Q1 to accurately function from ground to VCC –1.5 V differential input.
The output consists of an open collector NPN (pull-down or low side) transistor. The output NPN will sink current
when the negative input voltage is higher than the positive input voltage and the offset voltage. The VOL is
resistive and will scale with the output current. Please see 图 6-3 for VOL values with respect to the output
current.
7.4 Device Functional Modes
7.4.1 Voltage Comparison
The TL331-Q1 operates solely as a voltage comparator, comparing the differential voltage between the positive
and negative pins and outputting a logic low or high impedance (logic high with pull-up) based on the input
differential polarity.

8.1 Application Information
TL331-Q1 will typically be used to compare a single signal to a reference or two signals against each other.
Many users take advantage of the open drain output to drive the comparison logic output to a logic voltage level
to an MCU or logic device. The wide supply range and high voltage capability makes TL331-Q1 optimal for level
shifting to a higher or lower voltage.

8.2.2 Detailed Design Procedure
When using TL331-Q1 in a general comparator application, determine the following:
• Input voltage range
• Minimum overdrive voltage
• Output and drive current
• Response time
8.2.2.1 Input Voltage Range
When choosing the input voltage range, the input common mode voltage range (VICR) must be taken in to
account. If temperature operation is above or below 25°C the VICR can range from 0 V to VCC – 1.5 V. This
limits the input voltage range to as high as VCC – 1.5 V and as low as 0 V. Operation outside of this range can
yield incorrect comparisons.

Below is a list of input voltage situation and their outcomes:
1. When both IN- and IN+ are both within the common mode range:
a. If IN- is higher than IN+ and the offset voltage, the output is low and the output transistor is sinking
current
b. If IN- is lower than IN+ and the offset voltage, the output is high impedance and the output transistor is
not conducting
2. When IN- is higher than common mode and IN+ is within common mode, the output is low and the output
transistor is sinking current
3. When IN+ is higher than common mode and IN- is within common mode, the output is high impedance and
the output transistor is not conducting
4. When IN- and IN+ are both higher than common mode, the output is low and the output transistor is sinking
current
8.2.2.2 TL331B-Q1 and TL391B-Q1 ESD Protection
The "B" versions add dedicated ESD protections on all the pins for improved ESD performance as well as
improved negative input voltage handling. Please see Application Note SNOAA35 for more information.
8.2.2.3 Minimum Overdrive Voltage
Overdrive Voltage is the differential voltage produced between the positive and negative inputs of the
comparator over the offset voltage (VIO). In order to make an accurate comparison the Overdrive Voltage (VOD
)
should be higher than the input offset voltage (VIO). Overdrive voltage can also determine the response time of
the comparator, with the response time decreasing with increasing overdrive. 图 8-2 and 图 8-3 show positive
and negative response times with respect to overdrive voltage.
8.2.2.4 Output and Drive Current
Output current is determined by the load/pull-up resistance and logic/pull-up voltage. The output current will
produce a output low voltage (VOL) from the comparator. In which VOL is proportional to the output current. Use
图6-3 to determine VOL based on the output current.
The output current can also effect the transient response. More is explained in the next section.
8.2.2.5 Response Time
Response time is a function of input over drive. See 节 8.2.3 for typical response times. The rise and fall times
can be determined by the load capacitance (CL), load/pullup resistance (RPULLUP), and equivalent collector-
emitter resistance (RCE).
• The rise time (τR) is approximately τR ~ RPULLUP × CL
• The fall time (τF) is approximately τF ~ RCE × CL
– RCE can be determined by taking the slope of 图6-3 in its linear region at the desired temperature, or by
dividing the VOL by Iout

9 Power Supply Recommendations
For fast response and comparison applications with noisy or AC inputs, it is recommended to use a bypass
capacitor on the supply pin to reject any variation on the supply voltage. This variation can eat into the
comparator's input common mode range and create an inaccurate comparison.
10 Layout
10.1 Layout Guidelines
For accurate comparator applications without hysteresis it is important maintain a stable power supply with
minimized noise and glitches, which can affect the high level input common mode voltage range. In order to
achieve this, it is best to add a bypass capacitor between the supply voltage and ground. This should be
implemented on the positive power supply and negative supply (if available). If a negative supply is not being

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
