Abstract

See full text

A high-voltage gate driver circuit configured to drive a high-side power switch and a low-side power switch includes an active dv/dt triggered ESD protection circuit coupled between a protected node and a power rail node. The active dv/dt triggered ESD protection circuit includes a dv/dt circuit controlling an ESD protection transistor connected between the protected node and the power rail node. The ESD protection transistor is turned on when an ESD event occurs at the protected node to conduct ESD current from the protected node to the power rail node. The dv/dt circuit is charged up after a time constant to disable the ESD protection transistor.
