概述

Description

LM5069MMX-1 is TI’s hot‑swap/high‑side switch controller (LM5069 family) in a compact MMX package. It drives an external power MOSFET to supervise a live rail, providing inrush current control and protection during power-up, hot-plug, or fault events.
Key features
- External MOSFET drive for series pass control
- Adjustable current limit via sense resistor
- Inrush soft-start to limit start-up surge
- Fault protection: overcurrent/short-circuit, over/under voltage (OVP/UVLO), thermal shutdown
- Fault/status signaling (status/ fault pins)
Typical use
- Put the MOSFET in the power path, sense current with Rsense, feed the sense to ISENSE/FB pins, and enable/disable via EN/SHDN. The device modulates the gate to limit current and protect the rail during insertion or fault conditions.
Applications
- Hot-swappable power rails in servers, storage devices, telecom gear, and other systems requiring controlled power-up and protection.
Note
- See the TI LM5069MMX-1 datasheet for exact pinout, electrical specs, and packaging.

Features

LM5069MMX-1 is a high‑voltage, integrated LED driver with an on‑chip switch (buck/boost) designed for constant‑current LED strings. Key features:
- Integrated high‑side switching regulator for buck/boost LED drive
- Wide input voltage range suitable for automotive/industrial use
- Programmable constant-current LED regulation via sense resistor
- Dimming options: PWM and DC/analog dimming inputs
- Fixed switching frequency with internal soft‑start
- Minimal external components required
- Protections: undervoltage, overvoltage, overcurrent, thermal shutdown, and LED open/short protections
- High efficiency and low quiescent current
- Package: MMX‑1, compact 8‑pin device
- Broad operating temperature range for harsh environments
Note: For exact electrical limits (voltage range, maximum current, switching frequency, etc.), consult the TI datasheet.

Package

LM5069MMX-1 comes in a 16-pin VQFN package (3.0 × 3.0 mm) with an exposed pad.

Pinout

- Pin count: 8 pins (MMX package).
- Function: High-voltage hot‑swap controller. Drives an external N‑channel MOSFET to limit inrush current and provide overcurrent/ fault protection for hot‑plug power rails. Includes enable input and fault output; uses a sense resistor to monitor current (operates up to ~60 V).

Manufacturer

Manufacturer: Texas Instruments (TI).
TI is an American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits for a wide range of industries.

Application

LM5069MMX-1 is a high-efficiency DC-DC regulator/controller. Common applications include automotive and industrial DC-DC power supplies, point‑of‑load regulators, telecom/datacom front ends, battery-powered equipment, LED lighting drivers, and solar/off‑grid systems. It supports compact, robust power conversion with protections (overcurrent, thermal, UVLO) suitable for harsh environments.
