This is a standard duration for most MCU and DSP reset inputs, but if your system needs a faster restart, you will need an external watchdog or a supervisor with a programmable timeout. ## RoHS non-compliance: what it means for your BOM The MAX6703LKA is listed as RoHS non-compliant. This is an important flag for any design targeting lead-free assembly per EU RoHS directives. There is no last-time-buy or end-of-life pressure. However, the RoHS restriction may limit its use in new designs for European markets or medical devices. ## Sourcing and supply posture For volume production commitments, we can support blanket orders with scheduled releases. The RoHS non-compliant status means we verify date-code and marking consistency on every lot to ensure the parts match the original Maxim factory specifications.","metaTitle":"MAX6703LKA Power Supply Monitor, 3-Channel, SOT-23-8","metaDescription":"MAX6703LKA is a 3-channel power supply monitor with active-low reset, open-drain output, 120ms timeout. -40°C to 125°C.

This allows supervision of a 5V rail plus two lower-voltage rails such as 3.3V and 1.8V."},{"question":"Is MAX6703LKA equivalent to MAX6703?","answer":"The MAX6703LKA is a specific package variant of the MAX6703 family in SOT-23-8. The base MAX6703 part number may refer to a different package (e.g., DIP or SOIC) or a different temperature grade. Verify the package code and temperature range on your BOM before substituting. The LKA suffix specifically denotes the SOT-23-8 package and -40°C to 125°C range."},{"question":"What are the replacement options for MAX6703LKA?","answer":"Within the same family, an RoHS-compliant variant (if available) would be the direct replacement. Pin-compatible supervisors from other manufacturers exist with similar threshold options, but the adjustable channels and open-drain output must match. Cross-reference against Maxim's own MAX6700 series or Texas Instruments TPS3xxx series for form-fit-function alternatives. Confirm the reset timeout and threshold accuracy against your system requirements before substituting."},{"question":"What is MAX6703LKA's listed type?","answer":"The MAX6703LKA is listed as a Power Supply Monitor. It is a voltage supervisor IC that monitors up to three supply rails and asserts a reset signal when any rail falls below its threshold."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6703LKA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6703LKA when reusing this data.
