Product details

What the MAX805LESA does on your board

Housed in an 8-SOIC surface-mount package, it operates over the industrial temperature range of -40°C to 85°C, making it suitable for factory automation, telecom infrastructure, and embedded controllers that need reliable power-on reset and brownout protection.

Threshold and timeout — why they matter for fit

The 140ms minimum reset timeout gives the power supply time to ramp and settle after a brownout or power-up. For processors with fast-start oscillators (under 10ms), this is generous headroom; for systems with large bulk capacitance on the supply, it ensures the reset is not released prematurely.

RoHS non-compliant — plan accordingly

The MAX805LESA is marked as RoHS non-compliant. This part is intended for legacy BOMs, repair, or maintenance of existing equipment where lead-free assembly is not required. For new designs that must meet RoHS directives, a compliant alternative should be selected.
