The Power Switch Series NCT352x consists of 5 different parts of high-side power switches. All of these parts are suitable for 3V and 5V systems. They incorporate a 70mΩ or a 80mΩ N-channel MOSFET and provide up to 2.5A or 2.0A output current respectively.
These power switches are designed for high-side load switching applications like protection switches or hot plug devices.
There are two versions of the NCT3527, the NCT3527U and the NCT3527U-A. Difference is the current limit function.
The output current is limited when the output load reaches the current-limit threshold and a guaranteed deglitching time of 3-ms ensures that the transient voltage settles down.
If after this blanking time the load current is greater than the current limit, the NCT3527U enters a latch-off state and the NCT3527U-A enters an auto-retry state.
In latch-off state, the switch is turned off and FLAG# is issued to the host. The switch can be turned on again by cycling the power. In auto-retry state, the switch would be turned off for 24ms then turn-on again.
