LM3880MFX-1AD/NOPB | TI Three-Rail Power Sequencer Controller | 2.7-5.5V Input | Low Quiescent Current

Product Overview

     The LM3880MFX-1AD/NOPB from Texas Instruments is a simple power-sequencer designed to manage power-up and power-down sequencing of multiple independent voltage rails. Operating from 2.7 V to 5.5 V input range and a low quiescent current of about 25 µA, the device comes in a compact 6-pin SOT-23 package (approx. 2.9 mm × 1.6 mm). When the enable (EN) pin is asserted, the three open-drain outputs (FLAG1, FLAG2, FLAG3) are released sequentially after programmed delays, allowing connected power supplies to start in a controlled order. During power-down the flags go in reverse to avoid latch-up. Up to three parts can be cascaded to manage up to nine voltage rails.

Key Features

• Three-rail voltage sequencing (3 FLAG outputs)
• Input voltage: 2.7 V to 5.5 V
• Ultra low quiescent current: ~25 µA
• Compact 6-pin SOT-23 package (~2.9 mm × 1.6 mm)
• Easily cascade up to three devices to control up to nine voltage rails
• Controlled power-up and power-down sequencing helps prevent latch-up and surge currents
• Operating temperature range: -40 °C to +125 °C

Applications

• Multi-rail power systems (FPGA, microprocessors, ASICs)
• High-performance camera modules / vision sensor power-up sequencing
• Telecommunications, network equipment power modules
• Portable electronics power management designs
• Automotive electronics & industrial control systems requiring precise power-up/power-down control
