Product details
Overview
The MAX6467XS23D3+T from Analog Devices is a microprocessor supervisory reset circuit in SC70-4 package, monitoring +2.3V supply with ±2.5% threshold accuracy over -40°C to +125°C, asserting active-low open-drain RESET on VCC drop or edge-triggered MR input, and delivering 150ms min reset timeout-used in automotive engine control units for reliable brownout detection.
For engineers reviewing the MAX6467XS23D3+T datasheet, MAX6467XS23D3+T pinout, MAX6467XS23D3+T application, or MAX6467XS23D3+T equivalent, this page delivers verified electrical specs, thermal operating limits, MR debounce timing, RESET leakage current, and factory-trimmed threshold validation for AEC-Q100-compliant embedded designs.
Technical Context
This device implements a precision bandgap-based voltage reference with internal comparator and one-shot timer logic to generate deterministic reset pulses. Its edge-triggered manual reset ignores switch bounce via 150ms rising-edge debounce window and guarantees valid RESET output down to VCC = +1V.
The open-drain RESET output requires external pullup and supports noise-immune interfacing with µP reset inputs across wide VCC range (1.0V–5.5V); MR features internal 1.5kΩ pullup and accepts TTL/CMOS levels, enabling direct pushbutton connection without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | +2.3V nominal, ±2.5% over -40°C to +85°C - ensures accurate brownout detection for 2.5V systems with margin |
| Reset Timeout Period | 150ms minimum - meets µP reset assertion time requirements for ARM Cortex-M4 automotive firmware |
| Supply Current | 3µA at VCC = +1.8V - enables multi-year battery life in always-on vehicle telematics modules |
| Operating Voltage Range | +1.0V to +5.5V - supports operation during cold-crank conditions where battery dips to 6V system but local rail stays >1V |
| MR Rising Debounce | 150ms minimum - eliminates false resets from mechanical switch bounce in dashboard button interfaces |
| RESET Leakage | 1µA max (open-drain, not asserted) - prevents unintended pullup current loading in high-impedance reset networks |
| Temperature Range | -40°C to +125°C - qualified for under-hood automotive applications per AEC-Q100 Grade 0 |
Pinout & Package
Package: 4-pin SC70 (X4+1 outline, 21-0098 land pattern), 1.3mm × 1.0mm footprint, 0.5mm pitch, lead(Pb)-free/RoHS-compliant (+T suffix).
| 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 resistor (typically 10kΩ–100kΩ) to host VCC or dedicated reset rail |
| 3 MR | Edge-triggered manual reset input | Falling edge initiates one-shot 150ms RESET pulse; internal 1.5kΩ pullup allows NC if unused |
| 4 VCC | Power and monitored supply | Supplies internal circuitry and serves as monitored voltage; bypass with 0.1µF ceramic capacitor to GND |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed +2.3V threshold | Eliminates need for external resistor divider or trimming potentiometer in 2.5V domain power monitoring |
| Edge-triggered MR with one-shot | Guarantees single, fixed-duration reset pulse regardless of how long MR is held low-critical for deterministic boot sequences |
| 150ms reset timeout (D3 option) | Matches typical ARM-based MCU minimum reset hold time while minimizing system startup delay |
| VCC = +1V RESET validity | Ensures reset remains asserted through deep brownout events where supply collapses below 1.8V but stays above 1.0V |
| AEC-Q100 qualified | Validated for automotive use including temperature cycling, HTOL, and ESD testing-no additional qualification needed |
Applications
| Engine Control Unit (ECU) | Advanced Driver Assistance System (ADAS) Camera Module |
|---|---|
Use Scenario: Monitors 2.5V core supply during engine start-stop cycles where battery voltage sags to 6V causing regulator droop. IC Role / Device Role / Timing Role: Supervisory reset circuit asserting active-low RESET to MCU when VCC falls below +2.3V, with 150ms timeout ensuring full register initialization. Use Value: Prevents corrupted flash writes and state machine lockup during cold-crank brownouts by guaranteeing clean reset before firmware execution. | Use Scenario: Provides fail-safe reset to image signal processor during transient EMI events near radar transceivers. IC Role / Device Role / Timing Role: Edge-triggered manual reset input debounced for 150ms rejects switch bounce from housing-mounted service buttons. Use Value: Enables field-serviceable camera reboots without requiring power cycle-reducing diagnostic downtime in production line testing. |
| Automotive Infotainment Head Unit | Telematics Control Unit (TCU) |
Use Scenario: Watches 3.3V I/O rail feeding touchscreen controller and audio codec in infotainment SoC subsystem. IC Role / Device Role / Timing Role: Open-drain RESET output pulled up to 3.3V rail, compatible with multiple voltage domains and level-shifted reset trees. Use Value: Supports mixed-voltage reset architecture without additional level translators-reducing BOM count and PCB area. | Use Scenario: Ensures reliable reset during CAN bus wake-up events where 12V-to-3.3V DC/DC converter experiences ripple-induced dips. IC Role / Device Role / Timing Role: Immunity to short VCC transients (<100ns) prevents spurious resets during CAN transceiver switching noise. Use Value: Maintains cellular modem connectivity during intermittent power disturbances-avoiding SIM re-authentication delays. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar supervisory reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6315US23D3+T | Same SC70-4 package, identical +2.3V threshold and D3 timeout, but push-pull RESET output | Requires no external pullup; unsuitable where shared reset bus with other open-drain devices exists | Select when driving single-load MCU reset pin directly without bus contention concerns |
| TLV809E23DBZR | Lower quiescent current (0.5µA), same +2.3V threshold, but only 140ms min timeout and no MR debounce | Lacks edge-triggered MR-requires clean external debounced signal or adds RC network | Choose for ultra-low-power battery-backed modules where manual reset is rarely used and timing margin is tight |
Compared with MAX6467XS23D3+T, MAX6315US23D3+T offers push-pull drive for simpler layout but sacrifices bus-sharing capability, while TLV809E23DBZR reduces current draw but removes critical MR bounce immunity-making MAX6467XS23D3+T optimal for automotive manual reset interfaces.

FAQ
What is the exact reset threshold voltage for MAX6467XS23D3+T and its tolerance over temperature?
The MAX6467XS23D3+T has a nominal reset threshold of +2.3V, with ±2.5% tolerance over -40°C to +85°C and ±3% over +85°C to +125°C. This is factory-trimmed and specified in the Reset Threshold table of the datasheet; the '23' suffix explicitly denotes the +2.3V variant, confirmed by top-mark AGN on SC70 packages.
Does MAX6467XS23D3+T support manual reset functionality, and how is it implemented?
Yes, MAX6467XS23D3+T supports edge-triggered manual reset via the MR pin: a falling edge initiates a fixed 150ms one-shot RESET pulse, and internal 150ms rising-edge debounce prevents false triggers from switch bounce. The MR pin includes a 1.5kΩ internal pullup, allowing direct connection to a momentary switch without external components.
What package type and footprint does MAX6467XS23D3+T use, and is it RoHS-compliant?
MAX6467XS23D3+T uses the 4-pin SC70 package (outline 21-0098, land pattern 90-0187), measuring 1.3mm × 1.0mm with 0.5mm pitch. The '+T' suffix confirms lead(Pb)-free/RoHS-compliant tape-and-reel packaging, validated per JEDEC J-STD-020 moisture sensitivity level 1.
How does the open-drain RESET output of MAX6467XS23D3+T differ from push-pull alternatives?
The open-drain RESET output of MAX6467XS23D3+T requires an external pullup resistor and enables wired-OR reset bus configurations with multiple supervisors or logic devices. Unlike push-pull outputs, it avoids contention when sharing a common reset line-critical in complex automotive ECUs where multiple voltage rails must coordinate reset sequencing.
Is MAX6467XS23D3+T qualified for automotive applications, and what standards does it meet?
Yes, MAX6467XS23D3+T is AEC-Q100 qualified (Grade 0, -40°C to +125°C) and specified for automotive use. It meets stress test requirements including temperature cycling, high-temperature operating life (HTOL), and ESD (HBM ≥2kV). The '/V' designation in ordering codes confirms automotive qualification, and the +T suffix indicates RoHS compliance required for modern vehicle platforms.
