El Segundo, Calif. - International Rectifier has put a 12-volt complementary n- and p-channel pair of HEXFET power MOSFETs into a single SO-8 package. The IRF7338 targets double-data-rate DRAM memory.
When driven by an op amp, the IRF7338 can provide alternate source and sink paths for the termination voltage. In USB applications, it can instantaneously switch the USB port between the 5-V standby and 5-V core rails. In PCI applications, it can switch between the 3.3-V standby and the core rails. The p-channel section can switch currents of up to 3 amps; the n-channel side switches up to 6.3 A.
The IRF7338TR sells for 24 cents each in lots of 10,000.
