The LM3880MFE-1AC from Texas Instruments is a simple power supply sequencer that provides an easy method for controlling the power-up and power-down sequences of multiple independent voltage rails. By staggering the startup sequence, this IC helps to avoid latch conditions or large in-rush currents, thereby enhancing system reliability.
This device features three sequenced outputs and offers standard fixed time delay options including 2, 10, 16, 30, 60, and 120 ms. It operates with a low quiescent current of 0.025 mA and has an input voltage range of 2.7 V to 5.5 V. The LM3880MFE-1AC is available in a compact 6-pin SOT-23 package, measuring 2.9 mm x 1.6 mm, making it suitable for space-constrained applications.
The sequencer contains a precision enable pin and three open-drain output flags. These flags can be pulled up to distinct voltage supplies, allowing interface with ICs requiring different enable signals. The output flags follow a reverse sequence during power down to prevent latch conditions. It is possible to cascade up to three LM3880 devices to sequence as many as nine voltage rails.
