Working Principles

TSC426CPA+ operates by comparing the input voltage (IN) with the internally set threshold voltage (TH). When the input voltage falls below the threshold, the RESET pin is activated, pulling it low. Conversely, when the input voltage rises above the threshold, the RESET pin is released, allowing it to float or be pulled high externally.
