Texas Instruments LM3544MX-L/NOPB
- Part Number:
- LM3544MX-L/NOPB
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3263072-LM3544MX-L/NOPB
- Description:
- IC USB QUAD PORT SWITCH 16-SOIC
- Datasheet:
- LM3544MX-L/NOPB
Description
The LM3544 is a quad high-side power switch designed for use in USB (Universal Serial Bus) hubs. It features independent port enables, flag signals for error conditions, controlled start-up for hot-plug events, and short-circuit protection. The LM3544 accepts input voltages between 2.7V and 5.5V, and its low on-state resistance ensures compliance with USB voltage drop requirements.
Features
Compatible with USB1.1 and USB 2.0
90mΩ (typ.) high-side MOSFET switch
500mA continuous current per port
7ms fault flag delay filters hot-plug events
Industry standard pin order
Short circuit protection with power-saving current foldback
Thermal shutdown protection
Undervoltage lockout
Recognized by UL and Nemko CB
Input voltage range: 2.7V to 5.5V
5μA maximum standby supply current
16-pin SOIC package
Ambient temperature range: -40°C to 85°C
Applications
USB Root, Self-Powered, and Bus-Powered Hubs
USB Devices such as Monitors and Printers
General Purpose High Side Switch Applications
