Family of dual USB power switches

Diodes has expanded its AP21x1/x2 family with the introduction of the AP21x6 family of dual USB power switches. The switches offer a reduced footprint, improved switch on-resistance and better power dissipation. The family of devices complies with all USB standards and is available with both polarities of enable input. The family provides a cost effective, small form-factor implementation that offers complete protection for USB ports in different systems. The devices are offered in SO8 packaging and are rated for commercial applications. The power switches are also available in thermally enhanced MSOP-8L-EP packages, and are specified for operation over a temperature range of -40 to +85°C. Extended output current options are available at 0.5, 1 and 1.5A in both footprints. This enables these devices to be used to protect multiple USB ports for space conscious and low cost solutions. The switch family offers a faster response time, more accurate current limiting protection and reverse current blocking. The devices meet UL’s rigorous safety standards, file number E233275; and Nemko IEC 60950-1 CB Scheme.
