Abstract

In accordance with an embodiment, a method for electrostatic discharge (ESD) protection includes: dividing a voltage between a plurality of circuit nodes using a voltage divider circuit to form a divided voltage; compensating a temperature dependency of the divided voltage to form a temperature compensated divided voltage; monitoring the voltage between the plurality of circuit nodes using a transient detection circuit to form a transient detection signal; and activating a clamp circuit coupled between the plurality of circuit nodes based on the temperature compensated divided voltage and based on the transient detection signal.
