Power Switches Pack USB Protection

The company’s family of six high-side power switches include complete port protection for a wide range of self-powered and bus-powered USB and other hot-swap applications.  Designed to tolerate heavy capacitive loads and short circuits, the AP21x2A dual-channel devices are available with maximum load-current ratings of 0.5A, 1A, and 1.5A, and both polarities of an enable input. Other features include a transient response time of 2 µs, tolerance current limiting at ratings of 0.8A, 1.4A, or 2A, over-temperature and short-circuit protection, controlled rise-time and under-voltage lockout functionality, an automatic output discharge function to provide controlled discharge of disabled output capacitor voltage, and a 7-ms deglitch time on the power switch’s fault report flag. Pricing starts from $0.327 each/1,000. For further information, call Glen Wynn at Diodes Inc., Westlake Village, CA. (972) 385-6292.
