The LM3880MF-1AB 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 device helps to avoid latch conditions or large in-rush currents that can impact system reliability.
This sequencer features three sequenced outputs and offers standard time delay options including 2, 10, 16, 30, 60, and 120 ms. It operates with a low quiescent current of 25 µA and supports an input voltage range from 2.7V to 5.5V. The device is available in a compact 6-pin SOT-23 package with a footprint of 2.9 mm x 2.8 mm.
The LM3880MF-1AB includes a precision enable pin and three open-drain output flags. These flags can be pulled up to different voltage supplies, allowing interface with ICs requiring various enable signals. The output flags sequentially release after individual time delays during power-up and follow a reverse sequence during power-down to prevent latch-up conditions. It is possible to cascade up to three devices to sequence as many as nine voltage rails.
The LM3880MF-1AB has 3 sequenced outputs.
The available time delay options are 2, 10, 16, 30, 60, and 120 ms.
The typical quiescent current (Iq) is 0.025 mA.
The operating temperature range is -40 to 125°C.
The input voltage range is 2.7V to 5.5V.
The LM3880MF-1AB is available in a SOT-23 package.
