LM2901B-Q1、LM2901x-Q1 汽车类四路比较器

1 特性

3 说明

• 符合汽车应用要求

• 具有符合AEC-Q100 标准的下列特性：

LM2901B-Q1 器件是业界通用 LM2901x-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。

– 器件温度等级1：-40°C 至125°C 环境工作温度

范围

– 器件HBM ESD 分类等级：

• “AV”版本为1C 级

• 所有其他版本为2 级

所有器件都包含四个独立的电压比较器，这些比较器可

在宽电压范围内运行。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。

– 器件CDM ESD 分类等级C3

• 改进了“B”器件的2kV HBM ESD

• 单电源或双电源

• 独立于电源电压的

低电源电流：

“V”版本的工作电压高达 32V，“B”版本的工作电

压高达 36V。所有这些器件均符合 -40°C 至 +125°C

的AEC-Q100 1 级温度范围。

每个比较器200uA（典型值）（“B”版本）

• 低输入偏置电流：3.5nA（典型值）（“B”器件）

(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply

functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If

used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully

functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.

(2) All voltage values, except differential voltages, are with respect to network ground.

(3) Differential voltages are at IN+ with respect to IN−.

(4) Short circuits from outputs to V_CCcan cause excessive heating and eventual destruction.

temperature is P_D= (T_J(max)− T_A) / R_θJA. Operating at the absolute maximum T_Jof 150°C can affect reliability.

(1) The voltage at either input should not be allowed to go negative by more than 0.3 V otherwise output may be incorrect and excessive

input current can flow. The upper end of the common-mode voltage range is limited by V_CC–2V. However only one input needs to be

in the valid common mode range, the other input can go up the maximum V_CClevel and the comparator provides a proper output state.

Either or both inputs can go to maximum V_CClevel without damage.

(2) This parameter is ensured by design and/or characterization and is not tested in production.

(1) All characteristics are measured with zero common-mode input voltage, unless otherwise specified.

(2) Full range (MIN to MAX) is −40°C to 125°C. All characteristics are measured with zero common-mode input voltage, unless otherwise

specified.

(3) V_CCMAX = 30 V for non-V devices and 32 V for V-suffix devices.

(4) The voltage at either the input or common mode should not be allowed to negative by more that 0.3 V. The upper end of the common-

mode voltage range is V_CC+–1.5 V; however, one input can exceed V_CC, and the comparator will provide a proper output state as

long as the other input remains in the common-mode range. Either or both inputs can go to 30 V without damage.

7 Detailed Description

7.1 Overview

The LM2901-Q1 family is a quad 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 .

The open-drain output allows the user to configure the output's logic low voltage (V_OL) 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

7.3 Feature Description

LM2901-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 LM2901-Q1 to accurately function from ground to V_CC–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 6-19, 图 6-20 and 图 6-21 for V_OLvalues with

respect to the output current.

The special pinout of this device separates input pins from the output pins to reduce parasitic coupling between

input and output.

7.4 Device Functional Modes

7.4.1 Voltage Comparison

The LM2901-Q1 family of devices operates solely as a voltage comparator, comparing the differential voltage

between the positive and negative pins and outputs a logic low or high impedance (logic high with pullup) based

on the input differential polarity.

8.1 Application Information

LM2901-Q1 family 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 LM2901-Q1 optimal

for level shifting to a higher or lower voltage.

8.2.2 Detailed Design Procedure

8.2.2.1 Input Voltage Range

When choosing the input voltage range, the input common mode voltage range (V_ICR) must be taken in to

account. If temperature operation is above or below 25°C the V_ICRcan range from 0 V to V_CC–2.0 V. This limits

the input voltage range to as high as V_CC– 2.0 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. The "B" version output will go high.

8.2.2.2 Minimum Overdrive Voltage

The overdrive voltage is the differential voltage produced between the positive and negative inputs of the

comparator over the offset voltage (V_IO). To make an accurate comparison the overdrive voltage (V_OD) must be

higher than the input offset voltage (V_IO). The overdrive voltage can also determine the response time of the

comparator, with the response time decreasing as the overdrive increases. 图 8-2 and 图 8-3 show positive and

negative response times with respect to overdrive voltage.

8.2.2.3 Output and Drive Current

Output current is determined by the load/pull-up resistance and logic/pull-up voltage. The output current will

produce an output low voltage (V_OL) which is proportional to the output current. Use 图 6-19, 图 6-20, and 图

6-21 to determine V_OLbased on the output current.

The output current can also effect the transient response. More will be explained in the next section.

8.2.2.4 Response Time

The transient response can be determined by the load capacitance (C_L), load or pullup resistance (R_PULLUP), and

equivalent collector-emitter resistance (R_CE).

Use 方程式1 and 方程式2 to calculate the approximate values of the rise time (t_r) and fall time (t_f).

t_P≈R_PULLUP× C_L

t_N≈R_CE× C_L

(1)

(2)

To find the value of R_CE, use the slope of 图6-35 in the linear region at the desired temperature, or divide V_OLby

I_O.

9 Power Supply Recommendations

For fast response and comparison applications with noisy or AC inputs, TI recommends using a bypass

capacitor on the supply pin to reject any variation on the supply voltage. This variation can take away from some

of the input common mode range of the comparator 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).

11.4 静电放电警告

静电放电(ESD) 会损坏这个集成电路。德州仪器(TI) 建议通过适当的预防措施处理所有集成电路。如果不遵守正确的处理

和安装程序，可能会损坏集成电路。

ESD 的损坏小至导致微小的性能降级，大至整个器件故障。精密的集成电路可能更容易受到损坏，这是因为非常细微的参

数更改都可能会导致器件与其发布的规格不相符。
