That timeout window is sized for typical MCU oscillator start-up and power-rail settling — long enough to avoid a spurious release, short enough to keep the system responsive. ## Push-pull output — no external pull-up needed The output is active-low, push-pull (totem pole), so it drives the reset line high and low without requiring an external pull-up resistor. This simplifies the BOM and saves a resistor slot on the board. The output type is a direct match for the majority of processor reset inputs that expect a driven low level during power-up or brownout. ## Industrial temperature range — covers the usual suspects It is not specified for extended automotive under-hood or downhole environments where the junction temperature would push beyond 85°C.","metaTitle":"TPS3705-33DRG4 Voltage Supervisor, 2.93V Threshold","metaDescription":"Texas Instruments TPS3705-33DRG4 simple reset/power-on reset IC.
