Product details

4.6V threshold supervisor for single-rail monitoring

The MAX6806SA46: The active-low, push-pull output drives the reset line directly without an external pull-up resistor — the totem-pole stage sources and sinks current, which keeps the reset signal clean even with a long trace to the processor or FPGA.

SOIC-8 rework and board-fit

Surface-mount assembly on a two-layer board is feasible; the 1.27 mm lead pitch leaves room for a via between pads if the layout needs a mid-trace decoupling cap.

Industrial temperature and RoHS compliance

Marked RoHS non-compliant per the manufacturer's declaration, this part uses lead-bearing solder on the package terminations. The exemption applies to high-reliability or legacy BOMs that require tin-lead finish for solder-joint reliability under thermal cycling.

Frequently asked questions

What does the 4.6V threshold mean for my 5V rail?

The 4.6V threshold monitors a nominal 5V supply. It asserts reset when the rail drops below 4.6V — roughly 8% below nominal — which catches brownouts and power-supply sag before the downstream logic enters an undefined state.

Is MAX6806SA46 RoHS compliant?

No — the manufacturer lists it as RoHS non-compliant. The package uses tin-lead finish, which is exempt for certain applications under the RoHS directive. Verify your assembly's material declaration requirements before specifying.
