설명
유통업체에서 제공한 Texas Instruments LM809M3X-4.38/NOPB에 대한 설명입니다.
3-pin voltage supervisor (reset IC) with active-low, push-pull reset for supply monitoring 3-SOT-23
Processor Supervisor 4.45V 3V/5V/3.3V 3-Pin SOT-23 T/R
The LM809/810 microprocessor supervisory circuits can be used to monitor the power supplies in microprocessor and digital systems. They provide a reset to the microprocessor during power-up, power-down and brown-out conditions. The function of the LM809/810 is to monitor the VCC supply voltage, and assert a reset signal whenever this voltage declines below the factory-programmed reset threshold. The reset signal remains asserted for 240ms after VCC rises above the threshold. The LM809 has an active-low RESET output, while the LM810 has an active-high RESET output. Seven standard reset voltage options are available, suitable for monitoring 5V, 3.3V, and 3V supply voltages. With a low supply current of only 15uA, the LM809/810 are ideal for use in portable equipment. The LM809/LM810 are available in the 3-pin SOT23 package and in the 6-Lead LLP package.
