Product details
Overview
MAX6467XS16D3+T from Analog Devices is a precision microprocessor supervisory reset circuit in SC70-4 package, monitoring +1.8V supply with 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 ensures reliable power-on reset and brownout detection in automotive-grade embedded systems operating from -40°C to +125°C.
For engineers reviewing the MAX6467XS16D3+T datasheet, MAX6467XS16D3+T pinout, MAX6467XS16D3+T application, or MAX6467XS16D3+T equivalent, this page delivers verified electrical parameters, thermal behavior across temperature, MR debounce timing, VCC-to-RESET delay (35µs typical), and design-critical leakage/sink specifications for robust system-level reset integrity.
Technical Context
The MAX6467XS16D3+T implements a precision bandgap-based voltage reference with ±2.5% threshold tolerance over -40°C to +85°C and ±3% up to +125°C, coupled with analog comparators and digital one-shot timers. Its MR input features internal 1.5kΩ pullup and 150ms rising-edge debounce to suppress switch bounce.
Reset assertion is triggered by either VCC falling below 1.575V or a falling edge on MR, generating a fixed 150–300ms open-drain RESET pulse. The device remains functional down to VCC = +1V, with RESET valid throughout that range and 3µA supply current at +1.8V.
Key Specifications

Pinout & Package
MAX6467XS16D3+T is housed in a 4-pin SC70-4 package (outline 21-0098), measuring 2.0mm × 2.1mm × 0.9mm, with gull-wing leads and RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and RESET output sink path |
| 2 | RESET | Active-low open-drain output; requires external pullup; asserts low during VCC brownout or MR edge |
| 3 | MR | Edge-triggered manual reset input; internally pulled up to VCC with 1.5kΩ; falling edge initiates one-shot reset |
| 4 | VCC | Power supply input and monitored voltage rail; bypass with 0.1µF capacitor to GND for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Precision factory-set threshold | 1.575V nominal for +1.8V supply - eliminates external resistor divider and calibration |
| Edge-triggered MR with one-shot | Falling edge on MR generates exactly one 150–300ms RESET pulse - prevents latch-up from sustained button press |
| Immunity to short transients | Rejects VCC glitches <100ns wide at 100mV overdrive - avoids spurious resets in noisy environments |
| Low-VCC operation | RESET remains valid down to VCC = +1V - guarantees reset integrity during deep brownout recovery |
| Ultra-low quiescent current | 3µA at +1.8V - extends battery life in portable medical and GPS devices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6315US29D3+T | Same SC70-4 package, 2.925V threshold, 150ms timeout, but higher ICC (6µA at +1.8V) and no AEC-Q100 qualification | Targeted at industrial control, not automotive; lacks extended temperature validation | Select when 2.925V threshold matches +3.3V rail and AEC-Q100 is unnecessary |
| TLV803EB29DBZR | 2.93V threshold, SOT-23-3 package, 0.5µA ICC, but only rated to +85°C and no MR debounce circuitry | Suitable for cost-sensitive consumer electronics; requires external MR debounce | Choose for ultra-low-power +3.3V applications where automotive temp range and integrated MR timing are not required |
Compared with MAX6467XS16D3+T, MAX6315US29D3+T offers higher threshold and slightly higher current draw without automotive qualification, while TLV803EB29DBZR trades temperature range and integrated MR functionality for lower power and smaller footprint-making MAX6467XS16D3+T uniquely suited for AEC-Q100-compliant +1.8V systems requiring guaranteed 150ms reset timing and zero external components.

FAQ
What is the exact reset threshold voltage of MAX6467XS16D3+T and how does it vary with temperature?
The MAX6467XS16D3+T has a factory-trimmed reset threshold of 1.575V (min), 1.623V (typ), and 1.665V (max) at +25°C. Over -40°C to +85°C, tolerance is ±2.5%; from +85°C to +125°C, it widens to ±3%. This ensures accurate +1.8V supply monitoring across full automotive temperature range without external calibration.
Does MAX6467XS16D3+T support manual reset functionality, and how is it implemented?
Yes, MAX6467XS16D3+T features an edge-triggered manual reset (MR) input on Pin 3. A falling edge initiates a fixed 150–300ms one-shot RESET pulse. Internal 1.5kΩ pullup eliminates need for external resistor, and 150ms rising-edge debounce prevents false triggers from switch bounce - no external RC network required.
What is the RESET output type of MAX6467XS16D3+T, and what are its drive capabilities?
MAX6467XS16D3+T provides an active-low open-drain RESET output (Pin 2). It sinks up to 80µA while maintaining VOL ≤ 0.3V at VCC ≥ +1V. An external pullup resistor is mandatory; typical values range from 10kΩ to 100kΩ depending on bus capacitance and rise-time requirements.
How much supply current does MAX6467XS16D3+T draw, and how does it scale with voltage?
MAX6467XS16D3+T draws only 3µA (typ) at VCC = +1.8V, 4µA at +2.5V, 6µA at +3.6V, and 7µA at +5.5V. This ultra-low ICC enables multi-year operation in battery-powered devices like medical monitors and GPS trackers without compromising reset accuracy or timing.
Is MAX6467XS16D3+T qualified for automotive applications, and what standards does it meet?
Yes, MAX6467XS16D3+T is AEC-Q100 qualified for automotive use (Grade 0: -40°C to +125°C). It meets stringent reliability, thermal cycling, and ESD requirements for under-hood and cabin applications.
