– 有助于进行功能安全系统设计的文档
LM2903B-Q1 器件是业界通用 LM2903-Q1 比较器系
列的下一代版本。该下一代系列为成本敏感型应用提供
了卓越的价值，其特性包括更低的失调电压、更高的电
源电压能力、更低的电源电流、更低的输入偏置电流、
更低的传播延迟以及更高的 2kV ESD 性能，并提供了
直接替代的便利性。
所有器件都包含两个独立的电压比较器，这些比较器可
在广泛的电压范围内运行。如果两个电源的电压差处于
2V 至 36V 范围内且 VCC 比输入共模电压至少高
1.5V，那么也可以使用双电源。输出可以连接到其他
集电极开路输出。
LM2903-Q1 和 LM2903B-Q1 符合 -40°C 至 +125°C
的 AEC-Q100 1 级 温 度 范 围 。 LM2903E-Q1 符 合
-40°C 至 +150°C 的 0 级工作温度范围。

The voltage at any input should not be allowed to go negative by more than 0.3 V. The upper end of the input voltage range is VCC −
1.5 V for one input, and the other input can exceed the VCC level; the comparator provides a proper output state. Either or both inputs
can go to 36 V without damage.

Full range (MIN or MAX) for LM2903-Q1 is −40°C to 125°C and −40°C to 150°C for the LM2903E-Q1 . All characteristics are
measured with zero common-mode input voltage, unless otherwise specified.
VCC MAX = 30 V for non-V devices and 32 V for V-suffix devices.
The voltage at either input or common-mode should not be allowed to go negative by more than 0.3 V. The upper end of the commonmode voltage range is VCC+ − 1.5 V for the inverting input (−), and the non-inverting input (+) can exceed the VCC level; the
comparator provides a proper output state. Either or both inputs can go to 30 V (32V for V-suffix devices) without damage.

4 Detailed Description
4.1 Overview
The LM2903-Q1 family is a dual 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 it's very
wide supply voltages range (2 V to 36 V), low Iq and fast response.
This device is AEC-Q100 qualified and can operate over a wide temperature range of – 40°C to 125°C
(LM2903-Q1 and LM2903B-Q1) or –40°C to 150°C (LM2903E-Q1).
The open-drain 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 "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

4.3 Feature Description
LM2903-Q1 family 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 LM2903-Q1 to accurately function from ground to VCC–1.5V differential input.
This is enables much head room for modern day supplies of 3.3 V and 5.0 V.
The output consists of an open drain 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 3-3 in the 节 3.15 section for VOL values with
respect to the output current.
4.4 Device Functional Modes
4.4.1 Voltage Comparison
The LM2903-Q1 family 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.

5.1 Application Information
LM2903-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 LM2903Q1 optimal for level
shifting to a higher or lower voltage.

5.2.2.1 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– 2.0 V. This limits
the input voltage range to as high as VCC– 2.0 V and as low as 0 V. Operation outside of this range can yield
incorrect comparisons.

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. The "B" version output will go high.
5.2.2.2 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 5-2 and 图 5-3 show positive
and negative response times with respect to overdrive voltage.
5.2.2.3 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 3-5 to determine VOL based on the output current.
The output current can also effect the transient response. More will be explained in the next section.
5.2.2.4 Response Time
The transient response can be determined by the load capacitance (CL), load/pull-up resistance (RPULLUP) and
equivalent collector-emitter resistance (RCE).
• The positive response time (τp) is approximately τP ~ RPULLUP × CL
• The negative response time (τN) is approximately τN ~ RCE × CL
– RCE can be determine by taking the slope of 图 3-5 in it's linear region at the desired temperature, or by
dividing the VOL by Iout

5.3 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.
5.4 Layout
5.4.1 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
used, do not put a capacitor between the IC's GND pin and system ground.

6.5 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
