TLV803: Output Glitch with the TLV803SDBZR

Wayne,

That "glitch" is called "Power-up reset voltage" and is common for all supervisor devices across all TI and all competitors as well. That "glitch" is shown in Figure 1 as a grey undefined region when VDD is below its min operating voltage. The spec if also defined in the EC table 7.5. For this device, the output will go as high as 0.3V when VDD is less than 1.1V. For TLV809, the power-on reset voltage is as low at 2V. There is unfortunately no way to avoid that unless you use external circuitry.
