Applications
The MAX6315US29D3+T is used to supervise microprocessor and microcontroller supply rails in embedded systems, communications equipment, and industrial controllers, ensuring the CPU is held in reset until VCC stabilizes above 2.93 V. Its open-drain output and manual reset input make it easy to combine with other supervisors or pushbutton reset circuits in multi-rail processor boards.

Frequently Asked Questions
At what supply voltage does MAX6315US29D3+T assert a reset and how long does the reset remain active after power-up?
MAX6315US29D3+T monitors the supply rail and asserts RESET (active-low) when VCC falls below the 2.93 V threshold; after VCC rises back above the threshold, RESET remains asserted for a 336 ms timeout delay before releasing, ensuring the processor clock and oscillator have fully stabilized.
Why choose an open-drain reset output on MAX6315US29D3+T for a multi-processor board?
An open-drain RESET output allows multiple supervisor ICs or a pushbutton reset circuit to share a single wired-OR reset line; any device can pull the 2-wire bus low to hold all processors in reset simultaneously without contention, which simplifies board-level reset logic and reduces the GPIO count needed on the main MCU.
Which supply voltage rail levels can MAX6315US29D3+T monitor, and is it suitable for 3.3 V core logic?
MAX6315US29D3+T operates from 1 V to 5.5 V and uses a 2.93 V reset threshold, which directly matches the undervoltage monitoring requirements of 3.3 V logic rails; the threshold triggers reset with adequate margin below the nominal 3.3 V, protecting processors from executing code on an unstable supply.
How does the SOT-23-4 package of MAX6315US29D3+T help when board space is limited near the processor?
The 4-pin SOT-23 (R-PDSO-G4) footprint of MAX6315US29D3+T measures approximately 3 mm × 1.75 mm, allowing it to be placed within a few millimetres of the processor VCC decoupling capacitors for the shortest possible monitoring trace, while occupying minimal PCB area in dense embedded layouts.
