TI Introduces Quad Power Management Supervisor Family with Programmable Delay and Watchdog Timer

(Product News, 24 Nov 2009)

Texas Instruments Inc. has introduced a new family of quad supply voltage supervisors (SVSs) with programmable delay and watchdog timer, which minimize board space in today’s multi-rail power supply designs. The TPS386000, TPS386020, TPS386040, and TPS386060 supervisors can monitor four power rails that are greater than 0.4 V with a threshold accuracy of 0.25 percent. This accuracy combined with an integrated watchdog timer provides system reliability for processor-based applications. The TPS386000 family of devices offer an independent programmable delay input for each supervisor channel, which can be set from 1.25 ms to 10 seconds for power supply sequencing.

The TPS386000 devices operate with a very low quiescent current of 12uA, which can help minimize system power consumption. They are designed for applications such as telecom infrastructure, networking, server/storage, industrial and analog sequencing applications.
