Compact on-resistance MOSFET enhances battery pack operation
Toshiba Electronics has further expanded its comprehensive portfolio of power saving N-channel MOSFETs with the introduction of the SSM6N951L. Leveraging the company’s advanced power semiconductor process expertise and IP, this 12V-rated common-drain device exhibits numerous operational performance parameters.
The SSM6N951L is specifically intended for inclusion in the battery protection circuitry incorporated into the Li-Ion battery packs. Its ultra-low on-resistance (4.6mΩ maximum at a VGS of 3.8V) and minimal gate-source leakage current (1μA maximum at a VGS of 8V) mean that this power discrete device presents much lower thermal characteristics than those of the competition.
This is of real value during the battery packs’ charge/discharge cycles, allowing higher density solutions to be developed that support quicker charge rates, as well as having much greater reliability and a longer operational lifespan too.
These new MOSFETs are shipped in low-profile TCSP6A-172101 format packages (with dimensions of 2.14x1.67x0.11mm). As a result, they are optimised for implementation in modern space-limited battery powered equipment.
