It asserts both active-high and active-low reset outputs, giving the designer flexibility to match the reset polarity of the downstream processor or FPGA. The reset timeout is a minimum of 140ms, long enough to let most power supplies settle before the CPU starts executing code. ## Sourcing and lifecycle — active, but watch the RoHS flag This part is listed as RoHS non-compliant. If your assembly line or end-customer requires lead-free solder, you will need a waiver or an alternative part. For legacy builds or military/industrial contracts that explicitly allow tin-lead finishes, this is not an issue — but verify your own exemption status before committing the line. ## Threshold and timeout — what the numbers mean for your design The 140ms minimum reset timeout is a fixed delay, not programmable. It is long enough to cover most linear and switching regulator start-up times, but if your supply has an unusually slow ramp (e.g., a large capacitive load on a low-dropout regulator), verify that the rail is stable within that window. If the timeout expires before the rail is fully settled, the processor may start executing before the supply is within tolerance. Having both active-high and active-low reset outputs means you can drive the reset pin of any common processor without an external inverter. Many modern MCUs use active-low reset; some FPGAs or legacy CPUs use active-high. This part covers both cases from a single IC, saving a logic gate and a trace.","metaTitle":"MAX807MEUE Battery Backup Circuit, 4.575V Threshold","metaDescription":"MAX807MEUE is an active MPU supervisor with 140ms reset timeout, active high/low reset, industrial temp range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Battery Backup Circuit","Reset":"Active High/Active Low","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"16-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.575V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"16-TSSOP","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.61","stockQuantity":0,"priceTiers":[{"qty":54,"price":"$5.61000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4f1ee05e10b1c3c8d27e20549221bd17.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX807MEUE RoHS compliant?","answer":"No — this part is listed as RoHS non-compliant. If your assembly process requires lead-free solder per RoHS, you will need an exemption or a compliant alternative.

That is the delay from when the monitored voltage rises above the 4.575V threshold until the reset outputs de-assert."},{"question":"What is the closest pin-compatible alternative to MAX807MEUE?","answer":"Within the same Maxim supervisor family, the MAX807L and MAX807R variants offer different threshold voltages (4.65V and 4.40V respectively) in the same 16-TSSOP pinout. If you need a different trip point, those are direct drop-in swaps. For a RoHS-compliant version, check the MAX807MEUE+ (the plus suffix indicates lead-free finish) — verify pin compatibility with the datasheet."},{"question":"What is MAX807MEUE's listed type?","answer":"The device type is a Battery Backup Circuit, which functions as a microprocessor supervisor with battery-backup switchover for CMOS RAM or real-time clocks.
