摘要：
A device for controlling the voltage across an NMOS pull-up transistor including a source node which may be exposed to a variable voltage. The device further includes a gate node which may be exposed to a variable voltage. A control portion regulates the voltage applied to the gate node, wherein a differential in voltage between the source node and the gate node is limited to a desired level.
