Anachip AP1212
The AP1212 series are dual integrated high-side power switch with independent enable and flag functions, optimized for self-powered and bus-powered Universal Serial Bus (USB) applications. The AP1212 series support the following USB requirements: each switch channel supplies up to 500mA as required by USB downstream devices; the switch’s low on-resistance meets USB voltage drop requirements; fault current is limited to typically 1000mA, well below the UL 25VA safety requirements; and a flag output is available to indicate fault conditions to the local USB controller.| Part No. | AP1212 |

GENERAL DESCRIPTION
Soft start eliminates the momentary voltage drop on the upstream port that may occur when the switch is enabled in bus-powered applications. Additional features include thermal shutdown to prevent catastrophic switch failure from high-current loads, under voltage lockout (UVLO) to ensure that the device remains off...
