Texas Instruments Launches Power Management Controller

Texas Instruments Incorporated (TI) has introduced its single-chip, dual-slot hot swap manager for Advanced Mezzanine Cards (AdvancedMC) used in wireless, telecom and computing systems, including custom, AdvancedTCA (ATCA) and MicroTCA systems. The device significantly improves the flexibility and performance of hot swap power management design in applications ranging from 3G/Beyond 3G wireless base stations and network equipment to high-end data communications. The I2C-programmable TPS2359 hot swap controller performs all necessary power interface functions for two AdvancedMCs, while requiring the fewest possible external components. The TPS2359’s integrated ORing control capability simplifies power design for MicroTCA power modules or other implementations that manage redundant power in the AdvancedMC slot. The TPS2359 and TPS2358 are available today in volume from TI and its authorized distributors. The TPS2359 comes in a space-saving 36-pin, PQFN package with a suggested resale price of $5.00 in 1,000-piece quantities. The TPS2358 is available in a 48-pin QFN with a suggested resale price of $4.00 in 1,000-piece quantities. Evaluation modules of the TPS2358/9, design application notes and new Power Management Guide are available for download at
