Description The LM2901/2903 series comparators consist of four and two independent precision voltage comparators with very low input offset voltage specification. They are designed to operate from a single power supply over a wide range of voltages; however operation from split power supplies is also possible. They offer low power supply current independent of the magnitude of the power supply voltage.The LM2901/2903 series comparators are designed to directly interface with TTL and CMOS. When operating from both plus and minus power supplies, the LM2901/2903 series comparators will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.The dual devices are available in SO-8, TSSOP-8, and MSOP-8, and the quad devices available in SO-14 and TSSOP-14 with industry standard pinouts. Both use green mold compound as standard.Features•Wide Power Supply Range: ▪ Single Supply: 2V to 36V ▪ Dual Supplies: ±1.0V to ±18V•Very Low Supply Current Drain—Independent of Supply Voltage ▪ LM2903: 0.6mA ▪ LM2901: 0.9mA• Low Input Bias Current: 25nA • Low Input Offset Current: ±5nA •Typical Offset Voltage: ▪ Non-A Device: 2mV ▪ A Device: 1mV• Common-Mode Input Voltage Range Includes Ground• Differential Input Voltage Range Equal to the Power Supply Voltage•Low Output Saturation Voltage: ▪ LM2903: 200mV at 4mA ▪ LM2901: 100mV at 4mA• Output Voltage Compatible with TTL, MOS and CMOS• Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) •Halogen and Antimony Free. “Green” Device (Note 3)Pin Assignments(Top View)SO-8/TSSOP-8/MSOP-81OUT V CC2IN-2IN+1IN-1IN+GND2OUTLM2903/ LM2903A(Top View)SO-14/TSSOP-141OUT 3OUT GND4IN+3IN-3IN+4IN-2OUTV CC2IN-2IN+1IN-1IN+4OUTLM2901/ LM2901ANotes: 1.

Like most comparators, the series can easily oscillate if the output lead is inadvertently allowed to capacitive couple to the inputs via stray capacitance. This shows up only during the output voltage transition intervals as the comparators change states. Standard PC board layout is helpful as it reduces stray input-output coupling. Reducing the input resistors to <10kΩreduces the feedback signal levels. Finally, adding even a small amount (1.0mV to 10mV) of positive feedback (hysteresis) causes such a rapid transition that oscillations, due to stray feedback, are not possible. Simply socketing the IC and attaching resistors to the pins will cause input-output oscillations during the small transition intervals unless hysteresis is used. If the input signal is a pulse waveform, with relatively fast rise and fall times, hysteresis is not required. All input pins of any unused comparators should be tied to the negative supply.The bias network of the LM2901/2903 series comparators establishes a quiescent current independent of the magnitude of the power supply voltage over the range of from 2.0V DC to 30V DC.The differential input voltage may be larger than V CC without damaging the device. Protection should be provided to prevent the input voltages from going negative more than -0.3V DC (@ +25°C). An input clamp diode can be used as shown in the applications section.The output of the LM2901/2903 series comparators is the uncommitted collector of a grounded-emitter NPN output transistor. Many collectors can be tied together to provide an output ORing function. An output pull-up resistor can be connected to any available power supply voltage within the permitted supply voltage range and there is no restriction on this voltage due to the magnitude of the voltage applied to the V CC terminal of LM2901/2903 series comparator package. The output can also be used as a simple SPST switch to ground (when a pull-up resistor is not used).The amount of current the output device can sink is limited by the drive available (which is independent of V CC) and the β of this device. When the maximum current limit is reached (approximately 16mA), the output transistor will come out of saturation and the output voltage will rise very rapidly. The output saturation voltage is limited by the approximately 60ΩR SAT of the output transistor. The low offset voltage of the output transistor (1.0mV) allows the output to clamp essentially to ground level for small load currents.Typical Application Circuit (V CC = 5.0V DC )Typical Application Circuit(V CC = 5.0V DC) (continued)Typical Application Circuit (V CC = 5.0V DC ) (continued)Ordering Information (Note 15)LM290X X XXX - 13ChannelGrade3 : Dual PackingPackageS : SO-813 : Tape & Reel1 : Quad A : Low V IOBlank : Normal S14 : SO-14T14 : TSSOP-14M8: MSOP-8TH: TSSOP-8Part Number Package CodePackaging 13” Tape and ReelQuantity Part Number SuffixLM2901T14-13 T14 TSSOP-14 2500/Tape & Reel -13 LM2901AT14-13 T14 TSSOP-14 2500/Tape & Reel -13 LM2901S14-13 S14 SO-14 2500/Tape & Reel -13 LM2901AS14-13 S14 SO-14 2500/Tape & Reel -13 LM2903S-13 S SO-8 2500/Tape & Reel -13 LM2903AS-13 S SO-8 2500/Tape & Reel -13 LM2903AM8-13 M8 MSOP-8 2500/Tape & Reel -13 LM2903M8-13 M8 MSOP-8 2500/Tape & Reel -13 LM2903ATH-13 TH TSSOP-8 2500/Tape & Reel -13 LM2903TH-13THTSSOP-82500/Tape & Reel-13Note: 15.

我与TI易电源的故事
我与TI易电源的故事十年磨一剑，咱们学会用器件解决问题。
“十年磨一剑，霜刃不曾试。
”前人诗以言志，犹如十年寒窗苦读一朝展露锋芒。
而今的电子产品中，谈到历史，是不是也会有一种产品数十年如一日的精心雕琢？答案是确信的，有一个电源治理家族的产品，至今已有23年的历史，它确实是德州仪器的“SIMPLE SWITCHER”电源模块系列，中文名为“易电源”。
SIMPLE SWITCHER此刻是一个庞大的家族，由几个系列的产品组成，从第一代到第五代，和以后LMZ系列电源模块等许多的产品。
而“易电源”那个名字，也是最近几年在中国愈来愈受到欢迎后起的崭新的名字。
事实上，从1989年第一代LM257X到第三代LM267X三个系列在中国市场声名显赫，几乎是从诞生就进入到了中国，至今已经有20连年的历史，到今天仍然有许多的客户在利用。
后续推出的第四、第五代产品，和SIMPLE SWITCHER电源模块LMZ系列，与之前产品相较发生了庞大的转变。
这种转变来自于外界产品形态的转变，不管是工业、医疗仍是通信和消费电子，产品的小型化和低功耗要求日趋强烈，“易电源”家族的新成员在产品性能和尺寸上面都有专门大提升，伴随着特殊的封装和强劲性能优势，SIMPLE SWITCHER“易电源”产品系列成为德州仪器的明星产品，每一年有超过25000个客户订购那个产品。
补偿电路、仿电流模式、可调的软启动和开关同步、低电磁干扰、集成电感MOS管……似乎从SIMPLE SWITCHER中咱们找到了一个形容——“万千溺爱在一身”。
那个“易电源”功能上能够说达到了一个极致。

使能脚分压器、RENT 和 RENB选择 使能输入提供了精确的1.18V带隙上升阈值电压，允许采用直接逻 辑驱动或连接更高电压(如VIN)的使能分压器。使能输入包含 90 mV（典型）迟滞，造成阈值电压下降1.09V。EN引脚建议的最 大输入电压为6.5V。实际应用中，当使能分压器中点电压超过 6.5V时，可增加一个齐纳二极管限制电压。 该电阻分压器允许设计者选择输入电压值（低于该值则禁用电路 ）。这实现了欠压锁定的可编程功能。这通常用于电池供电系统 ，防止系统电池深度放电。在输出有时序控制的系统设计或防止 由于主输入电压上升期间的提前导通，这也非常实用。在高输入 电压的应用场合，使能分压器通常有主电源供电，这样工作范围 会比较窄。在时序上电应用中，相对于LMZ12003输出电压，分压 器由主电源提前上电。这两个电阻应基于以下比率选择： RENT/RENB =(VIN UVLO/1.18V）– 1 (1)
