Power: N-Channel MOSFET Drivers Handle 4.5- To 50-V Systems

Three of the driver ICs in the SiP series fit dc—dc switching power supplies, while a fourth includes a brake for brushless motor control applications. The SiP41103, SiP41104, and SiP41105 work with supply voltages from 4.5 V up to 50 V and supply drive currents up to 1 A. They switch at rates from 250 kHz to 1 MHz and exhibit a driver impedance less than 1 Ω. The SiP42101, which includes a brake function, operates at 50 kHz. All four are available now. The SiP42101 and SiP41103 have an MLP33-10 package. Pricing in 1000-piece lots is $1.96 for the SiP41101 and $1.83 for the SiP41103, SiP41104, SiP41105, and SiP42101. Lead times are eight to 10 weeks for larger orders.
