Product details
Overview
MAX810MEUR+T10 from Maxim Integrated is a 3-pin SOT23-packaged microprocessor supervisory circuit with push-pull active-high RESET output, precision 4.38V reset threshold (±1.5% over temperature), 140ms minimum reset timeout, and guaranteed operation down to VCC = 1V. It monitors +3.3V or +5V power rails in embedded controllers and automotive ECUs to prevent erroneous code execution during brownout.
For engineers reviewing the MAX810MEUR+T10 datasheet, MAX810MEUR+T10 pinout, MAX810MEUR+T10 application, or MAX810MEUR+T10 equivalent, this device delivers deterministic reset assertion for critical μP power sequencing, low-quiescent-current supervision in battery-backed systems, and AEC-Q100-qualified reliability in automotive environments.
Technical Context
The MAX810MEUR+T10 implements a precision bandgap-based voltage comparator with 30ppm/°C tempco to monitor VCC against a fixed 4.38V threshold. Its internal timer guarantees ≥140ms RESET pulse width after VCC rises above threshold, independent of supply ramp rate up to 100V/μs.
It features push-pull active-high RESET output capable of sourcing 500µA at 0.8×VCC while sinking 1.2mA at ≤0.3V, with full functionality maintained across –40°C to +105°C and VCC = 1.2V to 5.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.38V ±1.5% (guaranteed over –40°C to +105°C; enables reliable monitoring of +3.3V or +5V supplies) |
| Reset Timeout | ≥140ms (ensures μP completes internal initialization before release from reset) |
| Supply Current | 17µA typical at +25°C (enables multi-year battery life in portable instrumentation) |
| VCC Operating Range | 1.2V to 5.5V (supports valid reset assertion even during deep brownout down to 1.2V) |
| RESET Output Type | Push-pull active-high (eliminates external pullup; directly drives CMOS inputs without level-shifting) |
| Temperature Range | –40°C to +105°C (AEC-Q100 qualified for under-hood automotive applications) |
| Package | SOT23-3 (industry-standard footprint; compatible with automated PCB assembly) |
Pinout & Package
SOT23-3 package with 1.3mm × 2.9mm footprint, 0.95mm height, and gull-wing leads. RoHS-compliant lead-free finish (+ suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference | Return path for internal comparator and output stage; must be connected to system ground plane for noise immunity |
| 2 RESET | Active-high reset output | Drives high during VCC fault/brownout and for ≥140ms after recovery; sinks 1.2mA max when low, sources 500µA min when high |
| 3 VCC | Supply input | Monitored power rail input; accepts 1.2V–5.5V; internal circuitry remains functional down to 1.2V |
Key Features
| Feature | Design Value |
|---|---|
| Precision reset threshold | 4.38V ±1.5% over –40°C to +105°C ensures no false resets near nominal +3.3V/+5V rails |
| Guaranteed reset validity to VCC = 1V | Enables fail-safe behavior in deep brownout conditions where other supervisors lose output control |
| 12µA typical supply current | Reduces standby power in always-on automotive modules and portable medical devices |
| Transient immunity | Rejects VCC glitches ≤20µs at 100mV overdrive-no external filtering required for typical EMI environments |
| AEC-Q100 qualification | Validated for automotive Grade 3 (–40°C to +105°C) per stress test requirements |
Applications
| Automotive Engine Control Unit (ECU) | Industrial PLC Controller |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809MEUR+T | Same 4.38V threshold and SOT23-3 package, but active-low push-pull RESET output | Requires inverted reset logic on host μP; incompatible with active-high-only reset pins | Select when interfacing with legacy MCUs requiring active-low reset assertion |
| TPS3808G33DBVR | 3.3V fixed threshold, 200ms reset timeout, 1.5µA IQ, same SOT23-3 package | Optimized for +3.3V rails only; lacks AEC-Q100 qualification and wide VCC range (1.2V–6.5V) | Prefer for cost-sensitive consumer IoT nodes where automotive qualification is unnecessary |
Compared with MAX809MEUR+T and TPS3808G33DBVR, the MAX810MEUR+T10 uniquely combines AEC-Q100 qualification, active-high output, and 4.38V threshold - making it the only choice for automotive-grade +5V system supervision requiring non-inverted reset signaling.

FAQ
What is the exact reset threshold voltage of the MAX810MEUR+T10 and how tightly is it specified?
The MAX810MEUR+T10 has a nominal reset threshold of 4.38V, guaranteed between 4.25V and 4.50V over the full operating temperature range of –40°C to +105°C. This ±1.5% tolerance ensures reliable detection of brownout on +3.3V and +5V rails without false triggering near nominal voltage levels. The threshold exhibits only 30ppm/°C drift, minimizing thermal variation impact on system margin.
Does the MAX810MEUR+T10 require an external pullup resistor on its RESET pin?
No, the MAX810MEUR+T10 does not require an external pullup resistor because it features a push-pull active-high RESET output. Unlike open-drain supervisors such as the MAX803, the MAX810MEUR+T10 actively drives the RESET line high during fault conditions and low during normal operation-enabling direct connection to standard CMOS reset inputs without additional components.
Can the MAX810MEUR+T10 operate reliably when the supply voltage drops below 2.0V?
Yes, the MAX810MEUR+T10 is fully specified to operate down to VCC = 1.2V and guarantees valid RESET output behavior down to VCC = 1.0V. Its internal circuitry remains functional and asserts RESET correctly even during deep brownout events, making it suitable for battery-powered systems where supply voltage decays gradually.
Is the MAX810MEUR+T10 qualified for automotive applications?
Yes, the MAX810MEUR+T10 is AEC-Q100 qualified for Grade 3 (–40°C to +105°C) operation. Its SOT23-3 package, 140ms reset timeout, and precision 4.38V threshold meet stringent automotive requirements for engine control, body electronics, and ADAS subsystems where deterministic power-on reset behavior is essential.
How does the MAX810MEUR+T10 handle fast transients on the VCC supply line?
The MAX810MEUR+T10 incorporates built-in transient immunity: it ignores negative-going VCC glitches ≤20µs wide when the overdrive (VTH – VCC) is ≤100mV. This eliminates the need for external RC filters in typical EMI-prone environments like automotive or industrial settings-reducing BOM cost and board space while maintaining robust reset integrity.
