That means the reset signal goes high (logic 1) when the monitored voltage is below threshold or during the timeout period, and returns low when the system is out of reset. Most MCUs and MPUs expect an active-low reset input. If your processor requires a low-true reset, you need an inverter between the supervisor output and the processor reset pin, or you must select a different supervisor with an active-low output. Check the reset polarity of the downstream device before committing this part to the BOM. ## RoHS non-compliance — a sourcing gate for regulated markets The MAX805LCSA is listed as RoHS non-compliant. That is a hard gate for any BOM that must meet RoHS directives for the EU, California, or similar jurisdictions. If your design requires RoHS compliance, this part cannot be used without a waiver or exemption. There is no lead-free variant in this listing; a RoHS-compliant supervisor from the same or another family would be a separate order code.","metaTitle":"MAX805LCSA Battery Backup Circuit, Active-High Reset","metaDescription":"MAX805LCSA battery backup supervisor IC from Maxim Integrated.
