Diodes Incorporated's DMN2023UCB4 and DMP2100UCB9 are bi-directional MOSFETs that provide a superior protection switch for charging 1- and 2-cell lithium batteries. Their low-on-state resistance reduces power loss while their thin chip-scale packaging allows designers to use the space saved to increase battery capacity.

Designed to minimize the conduction losses whilst able to block current flow in both directions, these 20 V dual MOSFETs can be used as the battery switch for the low-side or high-side operation.
