That means no external pull-up resistors and the ability to interface with both reset-polarity conventions on the same board. The reset timeout is a minimum of 140ms, giving the system supply and oscillator enough time to settle before the processor starts executing code. For a 5V logic system, this part sits between the rail and the processor's reset input, with the backup battery connected to the VBAT pin.","metaTitle":"MAX691ACWE+ Battery Backup Circuit, 4.65V Threshold, 16-SOIC","metaDescription":"MAX691ACWE+ supervisor IC from Analog Devices.

MAX691ACWE+ is the 16-pin SOIC (surface-mount, 7.50mm width) variant, while MAX691ACPE+ is the 16-pin DIP (through-hole) variant. The electrical specifications — battery-backup circuit, 4.65V threshold, 140ms timeout, active high/low outputs — are identical between the two. The choice is purely a board-assembly decision: surface-mount reflow versus through-hole wave solder or socket."},{"question":"Can I use MAX691ACWE+ as a replacement for MAX691?","answer":"The base MAX691 (without the ACWE+ suffix) is the same die in an older package or temperature grade. The MAX691ACWE+ is the commercial-temperature, surface-mount version. Electrically it is a drop-in replacement for any MAX691 function: same battery-backup switchover, same 4.65V threshold, same reset outputs. Verify the package fit — if the original was a DIP, the SOIC footprint will not match without an adapter."},{"question":"What is MAX691ACWE+'s listed type and reset configuration?","answer":"Its listed type is Battery Backup Circuit, meaning it combines a voltage supervisor with automatic battery-switchover logic. Reset outputs are both active high and active low, push-pull, so no external pull-ups are needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX691ACWE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX691ACWE when reusing this data.
