Sunnyvale, Calif.—Supertex' PS12 is a power supply sequencer with four outputs, each capable of handling both power-up and power-down, for high-density, cost-sensitive telecom applications.
"The PS12 gives telecommunications and networking system manufacturers a space-saving, cost-effective solution for sequencing multiple supply rails," said Ahmed Masood, vice president of marketing. "With its power supply sequencing with multiple adjustable timers, the PS12 offers superior accuracy and reliability."
The PS12 includes an input voltage monitor, a power-on reset generator, four open-drain outputs, and seven timers. It controls up to four loads through outputs that can connect to the enable inputs of power supply modules either directly or through level-shifting or isolating drivers. The PS12 also features individually programmable delays of 5 ms to 200 ms, and an input voltage range of up to 90 volts.
