Diodes unveils bi-directional MOSFETs, cutting power loss

Keywords:Diodes? MOSFET? lithium batteries?

Diodes Inc. has introduced a bi-directional MOSFET that promises to deliver superior protection for charging 1- and 2-cell lithium batteries. The DMN2023UCB4 has a low on-state resistance that reduced power loss while its thin chip-scale packaging allows designers to use the space saved to boost battery capacity.

Geared to reduce on-state resistance for lower power loss, the DMN2023UCB4 delivers an RSS(on) of less than 26m. In addition, its dual N-channel common-drain configuration particularly suits the charging circuits required for 1- and 2-cell lithium batteries, which commonly use a low-side battery switch. For applications requiring a high-side connection Diodes also offers the DMP2100UCB9, which provides a dual P-channel common-source MOSFET design.


The above features coupled with a chip-scale package footprint of just 1.8mm x 1.8mm and a thickness of 2kV.

Target end-markets for the devices include smartphones, tablets, cameras, portable media players, and similar consumer products where size, weight and battery life are all key performance factors.

The DMN2023UCB4 and DMP2100UCB9 are available for 10,000-piece quantities each.
