Product details
Overview
MAX6467XS16D3-T from Maxim Integrated is a microprocessor supervisory reset circuit in SC70-4 package, featuring factory-trimmed 1.575V reset threshold (±1.5% at +25°C), 150ms minimum reset timeout, active-low open-drain RESET output, and edge-triggered manual reset input. It monitors single +1.8V to +5.0V supplies and ensures reliable reset assertion during power-up, brownout, or manual intervention in automotive-grade embedded systems.
For engineers reviewing the MAX6467XS16D3-T datasheet, MAX6467XS16D3-T pinout, MAX6467XS16D3-T application, or MAX6467XS16D3-T equivalent, key selection criteria include its 1.575V threshold tolerance, -40°C to +125°C operation, 3µA supply current at 1.8V, VCC-valid-to-1V behavior, and compatibility with noise-prone industrial reset environments requiring glitch immunity and switch-bounce rejection.
Technical Context
The MAX6467XS16D3-T implements a precision bandgap-based voltage monitor with temperature-compensated threshold detection across -40°C to +125°C. Its internal one-shot timer generates fixed 150ms (min) reset pulses on both VCC dropout and MR falling-edge events, with independent 150ms rising-edge debounce to suppress switch bounce.
It features an open-drain RESET output requiring external pullup, internal 1.5kΩ MR pullup resistor, and immunity to transients ≤100ns-enabling robust operation in electrically noisy automotive and industrial control applications without external filtering components.
Key Specifications

Pinout & Package
MAX6467XS16D3-T is housed in a 4-pin SC70-4 package (2.0mm × 2.1mm × 0.9mm), optimized for space-constrained PCB layouts in portable and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | Return path for internal biasing and RESET sink current; must be low-impedance connection to system ground plane |
| 2 - RESET | Active-low open-drain output | Drives low during reset; requires external pullup (typically 10–100kΩ) to host VCC or separate rail |
| 3 - MR | Edge-triggered manual reset input | Falling edge initiates 150ms one-shot reset pulse; internal 1.5kΩ pullup allows NC if unused |
| 4 - VCC | Power supply and monitored voltage | Supplies device and serves as monitored rail; bypass with 0.1µF ceramic capacitor to GND for transient immunity |
Key Features
| Feature | Design Value |
|---|---|
| Precision factory-set threshold | 1.575V with ±1.5% initial accuracy eliminates need for external resistor divider calibration |
| Edge-triggered MR with one-shot timing | Guarantees exactly one 150ms reset pulse per button press, regardless of contact bounce duration |
| Low 3µA quiescent current | Enables use in always-on battery-backed subsystems (e.g., real-time clock supervisors) without measurable drain |
| VCC-valid-to-1V operation | Ensures RESET remains asserted until VCC recovers sufficiently to support µP core logic, preventing premature release |
| Glitch-immune monitoring | Rejects transients ≤100ns, eliminating false resets caused by switching noise on shared power rails |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar supervisory reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6315US29D3-T | Same SC70-4 package, 2.93V threshold, 140ms min timeout, higher 8µA ICC at 1.8V | Designed for +3.3V systems; not suitable for 1.8V brownout detection | Select only if monitoring 3.3V rail with tighter 2.93V threshold requirement |
| TLV803EC26DBVR | SC70-5 package (5-pin), 2.63V threshold, 200ms min timeout, 0.5µA ICC, no MR input | Fixed-reset-only function; lacks manual reset capability and automotive temp range | Choose when manual reset is unnecessary and ultra-low current (<1µA) dominates design priority |

FAQ
What is the exact reset threshold voltage of the MAX6467XS16D3-T and how tightly is it specified?
The MAX6467XS16D3-T has a factory-trimmed reset threshold of 1.575V, guaranteed over temperature with ±1.5% tolerance at +25°C and ±2.5% from -40°C to +85°C. This precise value targets reliable supervision of 1.8V logic rails while accommodating typical supply tolerances and aging drift-ensuring the MAX6467XS16D3-T asserts reset before the µP enters undefined operation.
Does the MAX6467XS16D3-T support manual reset, and how does its edge-triggered behavior differ from level-sensitive alternatives?
Yes, the MAX6467XS16D3-T features an edge-triggered manual reset (MR) input that responds only to the falling edge, generating a fixed 150ms one-shot RESET pulse regardless of how long MR is held low. Unlike level-sensitive reset ICs, this eliminates unintended multiple resets from switch bounce or sustained MR assertion-making the MAX6467XS16D3-T ideal for tactile-button interfaces in automotive and portable equipment.
What is the minimum supply voltage at which the MAX6467XS16D3-T guarantees valid RESET output behavior?
The MAX6467XS16D3-T guarantees RESET remains valid (i.e., correctly asserted or deasserted) as long as VCC stays above +1.0V. Below +1.0V, internal circuitry cannot maintain defined logic states. This feature ensures the MAX6467XS16D3-T holds RESET active during deep brownout conditions common in automotive stop-start systems, preventing premature µP release before stable power resumes.
Can the MAX6467XS16D3-T operate from a 1.8V supply, and what is its typical supply current at that voltage?
Yes, the MAX6467XS16D3-T operates across +1.0V to +5.5V and draws only 3µA typical supply current at VCC = +1.8V (with no load). This ultra-low ICC enables integration into always-on subsystems such as real-time clocks or sensor wake-up controllers powered by energy-harvesting sources or coin cells-extending operational lifetime without compromising reset accuracy or timing.
Is the MAX6467XS16D3-T pin-compatible with other Maxim supervisory ICs, and which ones are explicitly documented?
Yes, the MAX6467XS16D3-T is explicitly documented as pin-compatible with MAX811, MAX6315, MAX6384, and MAX6386 in the same SC70-4 package. This allows direct replacement in existing designs using those parts-provided the 1.575V threshold and 150ms timeout meet system requirements-reducing redesign effort while upgrading to the enhanced glitch immunity and automotive temperature range of the MAX6467XS16D3-T.
