Abstract
An electrostatic discharge (ESD) protection device to manage leakage current can, in response to a power good (PGOOD) signal, draw the gate terminal of an ESD clamp device to a voltage below ground. The device also drives an inverted copy of the PGOOD signal to a gated inverter, which can inhibit the gated inverter output from drawing the ESD clamp device gate terminal to ground. The ESD protection device also includes the ESD clamp device to, in response to the gate terminal of the ESD clamp device being drawn to a bias voltage less than ground, allow a leakage current to flow through the ESD clamp device that is less than a leakage current allowed to flow in response to the ESD clamp device gate terminal being drawn to ground.
