Supervisor IC with 4.65 V threshold and 140 ms timeout
The MAX705CSA+T is a simple reset/power-on reset supervisor IC from Maxim Integrated, monitoring a single voltage rail with a 4.65 V threshold and issuing an active-low reset for a minimum of 140 ms after the supply crosses back above the threshold. The push-pull, totem-pole output drives the reset line directly without an external pull-up resistor — a detail that matters when the downstream logic input lacks an internal pull-up or when the trace runs across a noisy board.
Lifecycle and compliance posture
No official successor or second-source cross-reference is recorded; for BOM redundancy, a functionally equivalent supervisor from the same family with the same threshold and timeout can be qualified at the board level.
