TEXAS INSTRUMENTS LM3881MME/NOPB 电源定序器, 3监视器, 2.7V-5.5V输入, VSSOP-8
The is a simple Power Sequencer with programmable time delay. The power sequencer offers the easiest method to control power-up and power-down of multiple power supplies switching or linear regulators. By staggering the start-up sequence, it is possible to avoid latch conditions or large inrush currents that can affect the reliability of the system. The simple sequencer contains a precision enable pin and three open-drain output flags. When the LM3881 is enabled, the three output flags will sequentially release, after individual time delays, thus permitting the connected power supplies to start-up. The output flags will follow a reverse sequence during power-down to avoid latch conditions. Time delays are defined using an external capacitor and the output flag states can be inverted by the user.
