Microchip Technology, Inc. Power Distribution Switches, Load Drivers UCS2114-1-V/LX

The UCS2114-1-V/LX is a dual USB port power switch capable of delivering up to 3.0A continuous current per port, with a maximum of 3.4A. It operates within a source voltage range of 2.9V to 5.5V and features an on-resistance of 18 mOc per switch. The device includes independent enable pins for each port, dual fault alert outputs, and supports constant current or trip mode current limiting. It is equipped with undervoltage and overvoltage lockout, back-drive protection, and auto-recovery fault handling. For communication, the UCS2114 supports SMBus 2.0/I¬=C protocols, allowing for programmable current limits and current monitoring without the need for external sense resistors. The device can be configured for per-port charge rationing and includes a BC1.2 discharge function. It operates over a wide temperature range of -40¬8C to +105¬8C and has passed automotive AEC-Q100 reliability testing. The UCS2114 is packaged in a compact 3x3 mm 20-pin VQFN format, making it suitable for space-constrained applications.
