Abstract
Disclosed are a method, system and apparatus for an improved fail safe I/O driver with pad feedback slew rate control are disclosed. In one embodiment, a pad driver circuit includes a pad node, an NMOS component, a feedback capacitor between the pad node and a gate of the NMOS component to control slew rate across a range of capacitor loads, a switch circuit between the pad node and the feedback capacitor, and a signal generator to generate a signal to control the switch circuit. The switch circuit to maintain a main driver circuit and a pre-driver circuit of the pad driver circuit in a fail safe state when an integrated circuit that includes the pad driver circuit is in the fail safe state. The pad driver circuit may include a PMOS component.
