Power Supply Monitor Complies With SSI Standard For Servers

A new multichannel voltage and current monitor with an integrated thermal management controller and on-chip EEPROM complies with the SSI standard for servers. The ADM1040 embeds all power supply monitoring and control capabilities previously found in discrete designs into a single chip, thereby cutting system costs. It also reduces board area significantly. Its capabilities include monitoring analog voltages, load currents, temperature and automatic cooling fan speeds, as well as various digital status signals. An on-chip d/a converter provides an analog ouput for fan speed control. Optimized for 24 x 7 systems, the IC is priced under $2.50 each/1,000.
