The 4.55V threshold is set for a nominal 5V system — it trips before the supply falls out of regulation, giving the downstream logic a clean reset before brownout conditions corrupt data. With a minimum reset timeout of 140ms, the output holds the system in reset long enough for the power supply and oscillator to stabilize after power-up or a glitch. ## Push-pull output saves a resistor on the BOM The push-pull, totem-pole output can both source and sink current, so no external pull-up resistor is needed — one fewer component to qualify and place. The active-low reset output is compatible with most microcontroller and DSP reset inputs that expect a low signal during power-up or fault. ## Industrial temperature range in an SOIC-8 footprint Housed in an 8-SOIC package (0.154\" width, 3.90mm body), it is a drop-in fit for existing 5V reset socket designs with a standard surface-mount footprint.","metaTitle":"TPS3705-50D Simple Reset/Power-On Reset IC, 4.55V Threshold","metaDescription":"Texas Instruments TPS3705-50D simple reset IC with 4.55V threshold, active-low push-pull output, 140ms timeout, SOIC-8, -40°C to 85°C.
