uP7566
Description
Features
The u P7566 is a current limited high-side switch designed for applications where heavy capacitive loads and shortcircuits are likely to be met. This device operates with inputs from 2.7V to 5.5V for both 3V and 5V systems. Its low quiescent current and shutdown current(<1u A) conserve battery power in portable.
The power switch is controlled by a logic enable input and driven by an internal charge pump circuit. When the output load exceeds the current-limit threshold or a short is present, the u P7566 asserts over current protection and limits the output current to a safe level by driving the power switch into saturation mode.
The u P7566 features glitch-blank fault flag that is asserted by over current and over temperature. The 8ms glitchblanking time allows momentary faults to be ignored, thus preventing false alarms to the host system.
Other features include soft-start to limit inrush current during plug-in, thermal shutdown to prevent catastrophic switch...
