STMicroelectronics has launched the industry's first integrated power-management solution for media-oriented systems transport (MOST) networks. Optimized for in-car multimedia and infotainment applications, the MOST network was originally developed for the automotive industry, but also has a wide range of applications in many other industries.
The new L5961 power management IC, which has been designed in cooperation with fabless semiconductor manufacturer SMSC to work with that company's MOST network processors, includes both the power supply and MOST-compliant power-management control logic, together with enhanced diagnostic and full system monitoring (power supply, network status, wake-up events, temperature).
A chipset combining the L5961 power-management IC and SMSC network processor can serve as a building block in any MOST network node, and provides significantly more independence from the individual applications that are connected to the network, in terms of turn-on/off timing and device failure, for example. Additionally, the combined chipset, once validated, can be placed in any MOST application without having to be redesigned and revalidated each time, according to ST.
Other features of the L5961 include an integrated 5 or 3.3 V, 650 mA DC-DC converter, which supplies the network processor and can also supply power to an external low-voltage application, two voltage regulators to supply power to the fiber-optic transmitter and fiber-optic receiver, a diagnostic transceiver for the network physical layer, and the integration of three battery detectors for voltage monitoring. In addition, the device features multiple power modes, including an ultrazero power mode that offers a typical quiescent current of only 5 μA, a considerably lower value than that achieved with discrete components.
Encased in a PowerSSO36 package, or in the PowerSO36 option for applications requiring a higher thermal dissipation, engineering samples of the L5961 are available now to lead customers. Full qualification of the L5961, ready for volume production, is planned for the third quarter. The L5961 is priced at $3 in quantities of 1000.
