Delivering an RDS(ON) of less than 26mΩ, the DMN2023UCB4 has been designed to minimise on-state resistance for lower power loss. Its dual N-channel common-drain configuration suits the charging circuits required for one- and two-cell lithium batteries, which commonly use a low-side battery switch.
Other features include a gate threshold voltage of less than 1V to fully enhance the channel under low voltage operation, and built-in gate protection against ESD voltages of more than 2kV. Diodes Incorporated also offers the DMP2100UCB9, which provides a dual P-channel common-source MOSFET design, for applications requiring a high-side connection.
Supplied in a 1.8×1.8mm chip-scale package with a thickness of less than 0.4mm, the DMN2023UCB4 and DMP2100UCB9 are priced at $0.25 and $0.35 each, respectively, in 10,000 unit quantities.
