Power Switches Handle Higher Currents For USB Apps

For higher current applications and optimized for use in self- and bus-powered USB and other 3V to 5V hot-swap applications, the single-channel AP2101 and AP2111 power switches provide a continuous output current up to 2A. Available in both SO-8 and MSOP-8L-EP packages, the devices offer a choice of active-low and active-high enable respectively. Other shared features include a transient response time of 5µs, reverse current blocking, over-current, over-temperature, and short-circuit protection, controlled rise time, under-voltage lockout, 2.45A current-limiting tolerance, and a 7-ms deglitch capability on the open drain flag output. Price for the AP2101 and AP2111 single-channel power switches starts at $0.225 each/1,000. DIODES INC., Westlake Village, CA. (805) 446-4800.
