High-accurate charge/discharge control in new ICs

A new member of ROHM's IC series, providing high-accurate charge/discharge control, monitoring and protection functions for Li-ion secondary battery packs, has been anounced today. The ML5218 is a Li-ion battery monitoring IC for packs of 5 up-to 16 cells detecting over-charge or over-discharge and over-current of each cell. This makes the device adaptable to systems using safer lithium iron phosphate batteries of multiple cells connected in series.

Compact metal power inductors feature profile of just 1.0mm

Compact metal power inductors feature profile of just 1.0mm
The new VLS-HBX series of compact metal power inductors has been announced by TDK. Featuring a high current capability and profile of just 1.0mm, the two new types have footprints of 2.0 mm x 1.6 mm and 2.5 mm x 2.0 mm respectively. Due to the use of a magnetic metal core material with a high saturation flux density, the power inductors offer rated currents of up to 6.0 A DC, depending on type.
