Product parameters
Characteristics of LM809 Accurate monitoring of power supply voltage Available threshold options: 2.63 volts, 2.93 volts, 3.08 volts, 4.38 volts, 4.63 volts. Excellent upgrade to MAX809 and MAX810. Fully specified 140ms minimum power-on reset pulse width, 240ms (typical) Active low reset output (LM809) Active high RESET output (LM810) Ensure that the RESET output is valid for VCC ≥ 1 v. Low supply current, typical 15µA Power transient immunity LM809 description LM809 and LM810 microprocessor monitoring circuits can be used to monitor the power supply in microprocessors and digital systems. They provide a reset for the microprocessor when it is powered on, powered off and powered off. The functions of LM809 and LM810 are to monitor the VCC supply voltage and send out a reset signal when the voltage drops below the reset threshold programmed by the factory. After VCC rises above the threshold, the reset signal remains valid for 240 ms LM809 has an active low RESET output, while LM810 has an active high RESET output. Seven standard reset voltage options are available for monitoring 5V, 3.3V and 3V supply voltages. The power supply current of LM809 and LM810 is only 15 µA, which is very suitable for portable devices. app; application Factory automation Building automation Programmable logic control renewable sources of energy Microprocessor system computer controller intelligent instrument Portable/battery-powered equipment automobile All the evaluation(0)
