Voltage-level trans­la­tor

Stmi­cro­elec­tron­ics has in­tro­duced a voltage- level trans­la­tor com­pli­ant with Se­cure Dig­i­tal ( SD) 13.0 stan­dard. The ST6G3244 cou­ples high-speed op­er­a­tion with very low power dis­si­pa­tion, sup­ported with the power-down mode. Data in­tegrity is se­cured through prop­a­ga­tion de­lays, elec­tro­mag­netic­in­ter­fer­ence fil­ters and sig­nal con­di­tion­ing.

The trans­la­tor in­cor­po­rates 15kv air-gap elec­tro­static dis­charge pro­tec­tion on the card side. The se­lecta­ble­sup­ply (1.8V or 2.9V), 6-bit bidi­rec­tional Cmos-level trans­la­tor for SD, mini-sd and mi­cro-sd mem­ory card is of­fered in BGA25 pack­age.

Low-loss SIC power de­vices

Re­ne­sas Elec­tron­ics Cor­po­ra­tion has launched three sil­i­con-car­bide (SIC) power de­vices with voltage tol­er­ance of 600V.

The RJQ6020DPM de­vice for crit­i­cal- con­duc­tion- mode power fac­tor cor­rec­tion (PFC) ap­pli­ca­tions com­bines in a sin­gle pack­age an Sic-schot­tky bar­rier diode (SBD) and two high- voltage power MOSFETS. The re­verse re­cov­ery time of SIC-SBD is 15 nanosec­onds. The RJQ6021DPM de­vice for con­tin­u­ous-con­duc­tion-mode PFC ap­pli­ca­tions com­bines in a sin­gle pack­age an SIC-SBD and two in­su­lated-gate bipo­lar tran­sis­tors. The RJQ6022DPM de­vice for in­verter half-bridge cir­cuits com­bines in a sin­gle pack­age two SICSBDS and two IGBTS.
