Two-rail supervisor with adjustable threshold and timeout
The MAX6751KA26-T is a multi-voltage supervisor from Analog Devices that monitors two supply rails simultaneously. One threshold is fixed at 2.625 V, the second is adjustable via external resistors, giving the designer flexibility to set the undervoltage trip point for a secondary rail. The reset timeout period is adjustable/selectable, which allows tailoring the power-on reset delay to match the downstream processor or FPGA's startup timing.
Housed in a SOT-23-8 package (supplier package SOT-23-8), it occupies minimal board area and is a surface-mount fit for compact power-management sections.
Note that this part is listed as RoHS non-compliant. For designs requiring RoHS compliance, verify the bill-of-materials exemption or consider a RoHS-compliant variant from the same family.
