What this supervisor IC does on the board
The MAX6751KA29-T is a supervisor/reset circuit IC from Maxim Integrated — the kind of part that holds a microcontroller or DSP in reset until the supply rail is stable, then releases it cleanly. It monitors the voltage and asserts a reset output if the rail drops below the threshold, preventing brownout corruption. This is a single-function, no-frills supervisor: no watchdog, no manual reset, just the core reset function for systems that need a reliable power-on sequence.
Lifecycle and compliance — what it means for your BOM
The catch: this part is RoHS non-compliant. If your assembly line is set up for lead-free solder and your BOM requires RoHS compliance across the board, this part will not pass inspection. That makes it a fit for legacy or military/aerospace builds where tin-lead solder is still specified, or for repair stock where the original board was built before RoHS took effect.
Sourcing this part against an RFQ
Because the MAX6751KA29-T is active and RoHS non-compliant, it occupies a narrow sourcing slot — not every distributor stocks it, and the ones that do may carry limited quantities. We source it to order against an RFQ through independent distribution, confirming availability and current pricing at quote time. If your BOM calls for this exact order code and your compliance team has signed off on the non-RoHS status, send an RFQ and we will quote the line.
