Dual-voltage supervisor with 4.63V fixed threshold
The MAX6707LKA-T is a power supply monitor from Analog Devices that supervises up to two voltage rails, with one threshold fixed at 4.63V. The active-low, open-drain reset output asserts when either monitored voltage drops below its threshold and holds for a minimum of 120ms after all rails return to tolerance — long enough for the system oscillator and core supply to settle before the CPU is released from reset.
Industrial temperature range and small-footprint package
Housed in an 8-pin SOT-23 package, the footprint is 2.9 mm × 1.6 mm — small enough for space-constrained designs like sensor nodes or handheld instruments. The surface-mount package is compatible with standard reflow profiles; no special handling beyond normal MSL precautions.
Active lifecycle, RoHS non-compliant — sourcing note
Note that this part is RoHS non-compliant. For designs requiring RoHS compliance, a lead-free variant or an exemption may be needed. Confirm the regulatory requirement for your target market before committing the BOM line.
