... The MAX4864L/MAX4865L/MAX4866L have a +2.85V UVLO threshold, and the MAX4867 has a +2.5V UVLO threshold. The MAX4865/MAX4866 have a 4.15V UVLO threshold. In addition, a ±15kV ESD protection is provided to the input when bypassed with a 1µF capacitor to ground. All devices are offered in a small 6-pin SOT23 and a 6-pin, 2mm x 2mm µ ...

... IO MOSFETs. In most situations, MOSFETs with RDS(ON) specified for a VGS of 4.5V work well. Also the V should be +30V for the MOSFET to withstand the full +28V IN range of the MAX4864L/MAX4865L/ MAX4866L/MAX4867. Table 1 shows a selection of MOSFETs which are appropriate for use with the MAX4864L/MAX4865L/MAX4866L/MAX4867. For most applications, bypass ADAPTER to GND with a 1µ ...
