Texas Instruments Inc. (TI, Dallas, TX) announced its Personal Computer Memory Card International Association (PCMCIA) and PC card power switch integrated circuit (IC) that supports all power management requirements for the new ExpressCard standard. The TPS2231 extends TI’s broad portfolio of PCMCIA and PC Card power management devices, and efficiently manages the power supplied to a single ExpressCard slot used in notebook and desktop computers, PDAs and digital still cameras.
The IC powers up and detects load failures in the card, removes power if the card fails, protects the surrounding system from damage, and instantly communicates power events to the microcontroller or digital signal processor electronically – all without having to shut down the system.
The TPS2231 ExpressCard power switch is available now in volume production. The device comes in a 24-pin, Power Pad™ TSSOP or 20-pin TSSOP package. Suggested resale pricing is $1 each in quantities of 1,000 units.
