Temperature detection of power switch using modulation of driver output impedance

This disclosure is directed to circuits and techniques for detecting or responding to temperature of a power switch. A driver circuit for the power switch may be configured to deliver a modulation signal to a control node of the power switch to control on/off switching of the power switch, wherein the driver circuit is further configured to modulate an output impedance of the driver circuit at the control node, perform one or more voltage measurements while modulating the output impedance of the driver circuit, and control the power switch based at least in part on the one or more voltage measurements.

Semiconductor package with predictive safety guard

The disclosure describes techniques for detecting failures or performance degradation of a device including an integrated circuit (IC) components in the field by including additional contacts, i.e. terminals, along with functional contacts of the circuit used for connecting the circuit to a system in which the circuit is a part. These additional contacts may be internal external to the package surface and may be used to measure dynamic changing electrical characteristics over time e.g. voltage, current, capacity, temperature and impedance. These electrical characteristics may be representative of one or more failure modes and may be treated as indicator for device state-of-health (SOH).
