GATE DRIVER SYSTEM FOR DETECTING A SHORT CIRCUIT CONDITION

DRIVE March 21, 2024
Source
A driver system includes a first half-bridge that generates a first load current at a first output node, a second half-bridge that generates a second load current at a second output node, a first voltage charging device coupled to the first output node, and a second voltage charging device coupled to the second output node. A method of detecting a short circuit condition in the driver system includes detecting a first charging time at which a first charging voltage of the first voltage charging device is charged to a first threshold voltage; detecting a second charging time at which a second charging voltage of the second voltage charging device is charged to a second threshold voltage; and detecting the short circuit condition on a condition that a time difference between the first charging time and the second charging time is less than a time difference threshold.
