Product details

Package and mounting

Housed in a 6-WFDFN package (6-uDFN 1.5x1 mm), this supervisor suits space-constrained designs like handheld instruments, sensor nodes, and compact control modules. Surface-mount assembly is standard; the small footprint leaves room for passives on dense PCBs.

Temperature grade and environment

Rated for -40°C to 125°C ambient, the MAX6387LT46D4+T covers industrial and automotive under-hood environments — motor drives, engine ECUs, outdoor telecom, and factory automation where the board sees wide thermal swings.

Lifecycle and sourcing

No end-of-life notice or last-time-buy window is in effect, so it can be specified into new designs without near-term obsolescence risk.

Frequently asked questions

What is the reset timeout of MAX6387LT46D4+T?

The reset timeout has a minimum duration of 1.12s. This ensures the processor stays in reset until both monitored rails are stable and bulk capacitance has charged.

What is the output type of MAX6387LT46D4+T?

The reset output is active-low, push-pull (totem pole). No external pull-up resistor is needed, which simplifies the BOM on multi-rail designs.

Can MAX6387LT46D4+T be used as a replacement for other MAX6387 variants?

The MAX6387 family shares the same pinout and function across threshold-voltage options. The LT46 variant has a fixed 4.63V threshold; other variants offer different fixed voltages. Verify the threshold matches your rail before substituting.
