Product details

Multi-Voltage Supervisor for Two-Rail Systems

The MAX6389XS29D1+T monitors two supply rails and asserts an active-low reset when either falls below its threshold. The first channel is fixed at 2.93V; the second is adjustable via external resistors.

Temperature Grade and Environment

Rated for -40°C to 125°C ambient, this supervisor suits industrial motor drives, automotive under-hood modules, and outdoor telecom gear where the PCB sees wide thermal swings. The SC-70-4 package is small enough for space-constrained designs like sensor nodes or ECU power sequencers.

Lifecycle and Sourcing

Listed as Active with ROHS3 compliance. The SC-70-4 reel is moisture-sensitive.

Frequently asked questions

What is the difference between MAX6389XS29D1+T and MAX6388XS29D1+T?

The MAX6388 is a single-voltage supervisor; the MAX6389 monitors two voltages. If your design only needs one reset threshold, the MAX6388 saves a pin and a resistor. For dual-rail systems, the MAX6389 eliminates a second supervisor IC.

What are the exact specifications of MAX6389XS29D1+T?

Multi-voltage supervisor monitoring two voltages. Fixed threshold 2.93V on channel one, adjustable on channel two. Active-low reset, open-drain output. Minimum reset timeout 1ms. Operating temperature -40°C to 125°C. Package SC-70-4. Surface-mount. ROHS3 compliant. Active lifecycle.
