Product details
Overview
MAX6467XS26D7-T from Maxim Integrated is a microprocessor supervisory reset circuit in SC70-4 package, monitoring +2.625V supply (±1.5% at +25°C, ±3% over -40°C to +125°C), asserting active-low open-drain RESET on VCC drop or edge-triggered MR input, with 1200ms min VCC reset timeout and 150ms min MR timeout - used in automotive GPS systems for reliable brownout detection and manual reset initiation.
For engineers reviewing the MAX6467XS26D7-T datasheet, MAX6467XS26D7-T pinout, MAX6467XS26D7-T application, or MAX6467XS26D7-T equivalent, key selection criteria include factory-trimmed 2.625V threshold accuracy, 1200ms reset timeout, -40°C to +125°C automotive qualification, open-drain output requiring external pullup, and immunity to <100ns MR glitches.
Technical Context
The MAX6467XS26D7-T implements a precision bandgap-based voltage monitor with hysteresis-free threshold detection and internal one-shot timing for both power-fail and manual reset paths. Its edge-triggered MR input ignores subsequent falling edges within 150ms debounce window after MR rises, eliminating switch bounce artifacts.
RESET assertion is synchronized to VCC crossing the 2.625V threshold (with ±3% variation over full temperature range) and remains valid down to VCC = +1V. The open-drain output supports flexible pullup voltage levels independent of VCC, enabling interfacing with diverse logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.625V (factory-trimmed, ±1.5% at +25°C, ±3% over -40°C to +125°C) - ensures accurate brownout detection for +2.5V/2.6V rails |
| VCC Reset Timeout | 1200ms min (D7 suffix) - guarantees sufficient reset hold time for slow-starting microcontrollers |
| MR Timeout | 150ms min - provides fixed-duration reset pulse regardless of MR button press duration |
| Supply Current | 3µA at VCC = +1.8V - enables ultra-low-power operation in battery-backed systems |
| Operating Range | +1.2V to +5.5V VCC - supports wide input voltage range including low-voltage embedded supplies |
| Temperature Range | -40°C to +125°C - qualified for under-hood automotive applications |
| Output Type | Active-low open-drain - requires external pullup; allows level-shifting and wired-OR configurations |
Pinout & Package
Package: 4-pin SC70 (X4+1 outline, 90-0187 land pattern), 1.3mm × 1.1mm footprint, 0.65mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference | Primary return path for internal circuitry and RESET sink current |
| 2 RESET | Active-low open-drain output | Drives low during reset; requires external pullup resistor to define logic-high level |
| 3 MR | Edge-triggered manual reset input | Falling edge initiates 150ms one-shot reset pulse; internal 1.5kΩ pullup to VCC |
| 4 VCC | Power and monitored supply | Provides operating power and serves as monitored voltage rail; bypass with 0.1µF capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Precision factory-set 2.625V threshold | Eliminates external resistor divider; maintains ±3% accuracy across full automotive temperature range |
| Edge-triggered MR with 150ms debounce | Rejects mechanical switch bounce and EMI-induced glitches on manual reset line |
| 1200ms VCC reset timeout | Ensures microcontroller reset hold time exceeds worst-case power-up stabilization delay |
| Open-drain RESET output | Enables shared reset bus with multiple devices and interface to higher-voltage logic domains |
| Valid operation down to VCC = +1V | Guarantees clean reset deassertion during deep brownout recovery before full supply restoration |
Applications
| Automotive GPS Modules | Industrial PLC Controllers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6386US26D3-T | Same 2.625V threshold and SC70-4 package, but 150ms VCC timeout (D3), push-pull output | Suitable where shorter reset hold time suffices and no external pullup is desired | Select for cost-sensitive industrial designs needing simpler layout without pullup resistor |
| TPS3808G33DBVR | 2.93V threshold (not 2.625V), SOT-23-5 package, 200ms timeout, open-drain output | Requires PCB redesign due to 5-pin layout and different threshold; lacks automotive temp rating | Consider only if 2.93V monitoring is acceptable and design tolerates non-automotive qualification |
Compared with MAX6467XS26D7-T, MAX6386US26D3-T offers identical threshold and package but shorter timeout and push-pull drive, while TPS3808G33DBVR demands layout changes and provides mismatched voltage monitoring - making MAX6467XS26D7-T optimal for automotive-grade 2.625V brownout protection with long-reset reliability.

FAQ
What is the exact reset threshold voltage of the MAX6467XS26D7-T?
The MAX6467XS26D7-T has a factory-trimmed reset threshold of 2.625V, with ±1.5% tolerance at +25°C and ±3% over the full -40°C to +125°C operating range. This value is confirmed in the Reset Threshold table of the datasheet and corresponds to the '26' suffix in the part number.
Does the MAX6467XS26D7-T support manual reset with debouncing?
Yes, the MAX6467XS26D7-T features an edge-triggered manual reset (MR) input with built-in 150ms rising-edge debounce (tDEB). It responds only to the first falling edge on MR and ignores subsequent edges within that window, eliminating switch bounce without external components.
What is the function of the open-drain RESET output in the MAX6467XS26D7-T?
The MAX6467XS26D7-T provides an active-low open-drain RESET output requiring an external pullup resistor. This configuration allows level translation, wired-OR reset buses, and compatibility with various logic families - unlike push-pull outputs which fix the high-level voltage to VCC.
Can the MAX6467XS26D7-T operate reliably during deep brownout conditions?
Yes, the MAX6467XS26D7-T guarantees valid RESET output down to VCC = +1V, ensuring clean reset assertion and deassertion even during severe supply droop. Its internal circuitry remains functional and noise-immune below typical microcontroller operating voltages.
Is the MAX6467XS26D7-T qualified for automotive applications?
Yes, the MAX6467XS26D7-T is specified for -40°C to +125°C operation and carries the automotive qualification marker (/V) in its full ordering code (e.g., MAX6467XS26D7-T/V). It meets AEC-Q100 stress test requirements for under-hood automotive electronics.
