AP2501/AP2511
2.5A SINGLE CHANNEL CURRENT-LIMITED POWER SWITCH
Description
The AP2501 and AP2511 are single channel current-limited
integrated high-side power switches optimized for Universal Serial
Bus (USB) and other hot-swap applications. The family of devices
complies with USB standards and is available with both polarities of
Enable input.
The devices have fast short-circuit response time for improved
overall system robustness, and have integrated output discharge
function to ensure completely controlled discharging of the output
voltage capacitor. They provide a complete protection solution for
applications subject to heavy capacitive loads and the prospect of
short circuit, and offer reverse current blocking, over-current, over-
temperature and short-circuit protection, as well as controlled rise
time and under-voltage lockout functionality. A 7ms deglitch
capability on the open-drain Flag output prevents false over-current
reporting and does not require any external components.
All devices are available in SO-8, MSOP-8, MSOP-8EP,
U-DFN3030-8 (Type E) and U-DFN2020-6 packages.
