TEXAS INSTRUMENTS LM809M3-4.38/NOPB 微控制器复位电路, 低电平有效复位, 1.2V-5.5V输入, SOT-23-3
The is a 3-pin Microprocessor Supervisory Circuit with active-low RESET output. The supervisory circuit can be used to monitor the power supplies in microprocessor and digital systems. It provides a reset to the microprocessor during power-up, power-down and brownout conditions. The function of the LM809 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.
