Texas Instruments announced the ADC34DSO75 at the Open Compute Project Global Summit on 12 October, saying the chip could monitor power rails in AI data centres remotely and around the clock. The analog-to-digital converter samples electrical signals at 3 gigasamples per second. TI says that speed, combined with processing on the chip, lets it detect and capture brief faults on low-voltage, high-current power rails at nanosecond resolution.
Investigating an unexpected outage could begin with a remotely captured power-rail fault rather than an on-site oscilloscope, if the monitoring works as TI describes. The company says brief glitches can otherwise escape existing monitoring and cause unplanned downtime.
TI also introduced the LMI800PS, an 800V isolated hot-swap controller that it says puts functions previously requiring five integrated circuits into one package and reduces board area by more than 60%. Its LMK6B oscillator delivers 9.6fs jitter at 625MHz, according to the company, which says precise timing matters as data transmission rates approach 3.2Tbps. TI Power Electronics Engineer David Reusch will present on 800V data-centre power design at the summit on 15 October.
