Electrostatic discharge clamp with disable
Abstract:
In a particular embodiment, a circuit includes a power supply, a ground, and a clamping transistor circuit coupled to the power supply and to the ground. The circuit further includes a disable clamp circuit. The disable clamp circuit is coupled to the power supply and is responsive to a second power supply input to selectively disable the clamping transistor circuit by modifying a charging current applied to a capacitor of the clamping transistor circuit. In a particular embodiment, modifying the charging current includes enabling a second charging path. Enabling the second charging path enables charging the capacitor at a higher charging rate than a charging rate associated with charging the capacitor via a first charging path.
