Suiting 24V utility metering, sensor interfacing, and other industrial motion-control and battery-powered data-acquisition equipment, the AS7620 hysteretic 32V step-down regulator provides early-power-fail warning and power-good signals to microcontrollers. The 500-mA buck regulator provides an integrated dual-power monitor, a fixed 3.3V output or an adjustable output-voltage of 1.2V to the input voltage. The regulator provides soft-start, current limiting, and thermal shutdown, drawing a 1-mA current during shutdown. Claiming 93% efficiency, the device integrates a 100% duty cycle, extending operation in low-dropout conditions. A pin-selectable peak-current limit reduces component size by adjusting inductor selection. Operating over a –40 to +85°C industrial-temperature range, the regulator also provides 37-µA operation when deli...Read More

Aiming at Profibus, DeviceNet, CAN, and RS485 industrial-communication standards, the FOD0710, FOD0720, and FOD0721 high-speed logic-gate optocouplers meet the qualifications for the UL1577 standard. The 25-Mbps-bandwidth devices features 13-mA supply currents, 4.5 to 5.5V supply voltages, and 20-kV/µsec minimum common-mode noise-rejection ratings. The vendor claims that the devices’ lead-free, coplanar packaging reduces package capacitance by more than 30%. The FOD0710, FOD0720, and FOD0721 optocouplers cost $2.21, $2.44, and $2.67 (1000), respectively.

Allowing remote monitoring of temperature and humidity to any location with Internet access, the Data Center System suits food-service rooms, warehouses, and long-term storage, as well as computer, server, and equipment rooms. Providing nonstop operation, the system sends an alert e-mail to the designated recipients when readings fall outside the customer’s predetermined limits. Users can view or download temperature and humidity data from any computer with Internet access. The DLP-UT1 sensor measures temperatures over a single channel and operates over 0 to 70°C. The DLP-UTH8 data-collection hub features eight channels, allowing connection to temperature-only or temperature-and-humidity modules using standard intranet cables. You can place the sensors as far as 250 ft away from the hub. The Data Center System service costs $29.95 for six months; the DLP-UT1 sensor and...Read More
