Description
Pin Assignments
OBSOLETE – PART DISCONTINUED
The AP2141A is integrated high-side power switch optimized for
Universal Serial Bus (USB) and other hot-swap applications. The
family of devices complies with USB 2.0 and is available with both
polarities of Enable input. They offer current and thermal limiting and
short circuit protection as well as controlled rise time and undervoltage lockout functionality. A 7ms deglitch capability on the opendrain Flag output prevents false over-current reporting and does not
require any external components.
