example 1

[0073] Example 1. A method comprising storing, by a logic circuit, an early warning threshold level of a parameter of a power switch to a memory. The method also includes receiving, by the logic circuit, a signal from the controller and setting, by the logic circuit, an early warning threshold level in response to receiving the signal from the controller. The method also includes determining, by the logic circuit, that the magnitude of the parameter of the power switch does not meet the warning threshold level. The method includes outputting, by the logic circuit, an alert to a controller in response to determining that the magnitude of the parameter does not meet an alert threshold level.

example 2

[0074] Example 2. The method of example 1, further comprising storing the shutdown level to non-volatile memory.

example 3

[0075] Example 3. The method of example 1 or example 2, further comprising determining that the parameter does not meet the shutdown level.

Abstract

Embodiments of the disclosure relate to a parameter threshold level based on a signal from a controller. In some examples, an apparatus includes a memory configured to store an early warning threshold level for a parameter of a power switch. The apparatus also includes logic circuitry configured to receive the signal from the controller and set an early warning threshold level in response to receiving the signal from the controller. The logic circuit is further configured to determine that the magnitude of the parameter of the power switch does not meet an early warning threshold level. The logic circuit is further configured to output an alert to the controller in response to determining that the magnitude of the parameter does not meet the early warning threshold level.

Description

technical field [0001] The present disclosure relates to power electronic devices. Background technique [0002] The power switch manages the current flow from the source to the load. When the power switch is activated by the microcontroller, power flows from the source to the load. If the current, voltage or temperature of the power switch exceeds safe thresholds, the power switch may be damaged. To prevent damage, logic on the power switching device or logic on the gate driver device can monitor these parameters and deactivate its output(s) when one or more parameters exceed respective safety thresholds. The microcontroller will receive the shutdown flag from the power switch, but the microcontroller cannot analyze the reason behind the shutdown flag to learn or even predict the next failure. SUMMARY OF THE INVENTION [0003] This disclosure describes techniques for setting an early warning threshold level for a parameter of a power switch based on a signal sent from ...
