It provides enough hold-off time for most microcontrollers and DSPs to complete their internal power-on reset sequence, oscillator startup, and initial register configuration before the supervisor releases the reset line. The 140ms figure is the minimum over temperature and supply; the actual timeout is typically longer, ensuring margin. If your processor requires a shorter or longer reset pulse, the MAX690RCSA+ is fixed — no external capacitor adjustment — so verify the timing against your MCU's datasheet requirement before committing the BOM line. ## Active production, no LTB risk It is ROHS3 compliant (lead-free) and remains a current-production part from Analog Devices.","metaTitle":"MAX690RCSA+ Battery Backup Circuit, Active-Low Reset, 8-SOIC","metaDescription":"MAX690RCSA+ battery backup supervisor with 140ms reset timeout, 2.625V threshold, push-pull output.

This is the guaranteed hold-off period after the supply rises above the 2.625V threshold before the reset output is released."},{"question":"What is the closest pin-compatible alternative to MAX690RCSA+?","answer":"The MAX690RCSA+ is from a broad family of Maxim (now Analog Devices) supervisory ICs. Pin-compatible alternatives with different voltage thresholds or reset timeout options exist within the same 8-SOIC footprint — for example, the MAX691 series offers a different threshold. Verify the exact threshold and output type against your design before substituting."},{"question":"Is MAX690RCSA+ compatible with 3.3V logic?","answer":"Yes, the 2.625V threshold is appropriate for monitoring a 3.3V supply rail. The reset output is push-pull and operates from the monitored supply voltage, so it drives 3.3V logic inputs directly without level translation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX690RCSA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX690RCSA when reusing this data.
