Product details
Overview
MAX810LEUR+T10 from Maxim Integrated is a 3-pin SOT23-packaged microprocessor supervisory circuit with push-pull active-high RESET output, 4.63V reset threshold (±2.5% over temperature), 140ms minimum reset timeout, 12μA supply current at +25°C, and guaranteed operation down to VCC = +1V. It monitors +5V power supplies in embedded controllers and portable equipment to prevent code-execution errors during power-up, brownout, or power-down.
For engineers reviewing the MAX810LEUR+T10 datasheet, MAX810LEUR+T10 pinout, MAX810LEUR+T10 application, or MAX810LEUR+T10 equivalent, this page delivers verified electrical parameters, thermal performance across –40°C to +105°C, SOT23 footprint compatibility, and design guidance for reliable reset assertion in battery-powered and automotive-qualified systems.
Technical Context
The MAX810LEUR+T10 implements a precision voltage comparator with 30ppm/°C tempco to detect VCC decline below 4.63V, asserting an active-high RESET signal until VCC remains above threshold for ≥140ms. Its push-pull output drives CMOS logic directly without external pullup resistors.
Designed for single-supply monitoring, it ignores fast transients ≤20μs at 100mV overdrive and maintains valid RESET output down to VCC = +1V-enabling robust reset behavior during deep brownout conditions where most μPs become nonfunctional.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63V ±2.5% (–40°C to +105°C); ensures reset assertion before +5V supply drops to 4.50V, preventing marginal operation. |
| Reset Timeout | 140ms min (–40°C to +85°C); guarantees μP initialization completes before firmware execution begins. |
| Supply Current | 12μA typ at +25°C; enables multi-year battery life in always-on portable instrumentation. |
| VCC Operating Range | 1.2V to 5.5V (–40°C to +105°C); supports operation during deep brownout while maintaining reset validity. |
| Output Type | Push-pull active-high RESET; eliminates need for external pullup and interfaces directly with μP reset inputs requiring high-true assertion. |
| Transient Immunity | Immune to ≤20μs negative-going VCC glitches at 100mV overdrive; prevents false resets from switching noise or ESD coupling. |
| Temperature Range | –40°C to +105°C; qualified for industrial and automotive under-hood applications per AEC-Q100. |
Pinout & Package
MAX810LEUR+T10 uses a 3-pin SOT23 package (JEDEC MO-178AA) with 1.3mm × 2.9mm footprint, 0.95mm height, and gull-wing leads. Pin 1 = GND, Pin 2 = RESET (active-high push-pull), Pin 3 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | Return path for internal comparator and output stage; must be low-impedance connection to system ground plane. |
| 2 - RESET | Active-high reset output | Drives high (≥0.8×VCC) when VCC ≥4.63V and stable; sinks current to ground when VCC <4.63V or during timeout period. |
| 3 - VCC | Supply input | Monitored +5V rail input; accepts 1.2V–5.5V; bypass capacitor (0.1μF) required within 5mm for transient immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Precision 4.63V threshold | ±2.5% tolerance over –40°C to +105°C ensures deterministic reset point across full industrial temperature range. |
| 140ms minimum reset pulse | Guarantees sufficient time for μP internal clocks, PLLs, and memory initialization before release. |
| 12μA quiescent current | Enables use in energy-harvesting and coin-cell-powered devices without compromising battery lifetime. |
| VCC = +1V reset validity | Maintains defined logic state on RESET pin even as supply collapses, eliminating floating-input risk in low-VCC states. |
| AEC-Q100 qualified | Validated for automotive applications including engine control modules and body electronics requiring high reliability. |
Applications
| Industrial Controllers | Portable Medical Devices |

Use Value: Ensures clean shutdown before battery voltage drops below μP operational minimum, preserving calibration data. |
| Automotive Body Control Units | Smart Energy Meters |
Use Scenario: BCM modules exposed to load-dump and cold-crank conditions causing +5V rail sag.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809LEUR+T | Same 4.63V threshold and SOT23 package, but active-low push-pull RESET output. | Requires μP with active-low reset input; incompatible with systems needing active-high assertion without level-shifting. | Select MAX809LEUR+T only if target μP reset pin is active-low and no logic inversion is permitted in PCB layout. |
| TPS3808G15DBVR | TI part with 1.5V threshold, adjustable delay, and 1.8–6V VCC range; 3.5μA typical ICC. | Not a direct voltage-threshold match; requires external resistor divider for +5V monitoring, increasing BOM count and board area. | Choose TPS3808G15DBVR only when programmable delay or ultra-low current (<5μA) outweighs fixed-threshold simplicity and zero-component advantage of MAX810LEUR+T10. |
Compared with MAX809LEUR+T, MAX810LEUR+T10 avoids external inverters in active-high reset architectures; versus TPS3808G15DBVR, it eliminates calibration components and reduces layout complexity for fixed +5V supervision-making it optimal for cost-sensitive, space-constrained industrial controllers.

FAQ
What is the reset threshold voltage of the MAX810LEUR+T10 and how stable is it over temperature?
The MAX810LEUR+T10 has a nominal reset threshold of 4.63V with ±2.5% tolerance over the full operating range of –40°C to +105°C. Its 30ppm/°C tempco ensures minimal drift-e.g., threshold variation stays within ±15mV from +25°C to +85°C-making it suitable for applications demanding precise +5V rail monitoring without recalibration.
Does the MAX810LEUR+T10 require an external pullup resistor on its RESET pin?
No, the MAX810LEUR+T10 features a push-pull active-high RESET output and does not require an external pullup resistor. Unlike open-drain variants (e.g., MAX803), it actively drives high (≥0.8×VCC) and low (≤0.4V) states, enabling direct interface with μP reset inputs expecting active-high assertion without additional components.
Can the MAX810LEUR+T10 operate reliably when VCC drops below 2.0V?
Yes-the MAX810LEUR+T10 guarantees valid RESET output down to VCC = +1.2V over temperature (–40°C to +105°C). Below 1.2V, RESET remains asserted (high) until VCC recovers above 4.63V, and the device continues functioning correctly through brownout, supporting graceful shutdown sequences in low-power systems.
What is the minimum reset timeout duration of the MAX810LEUR+T10 and is it guaranteed across temperature?
The MAX810LEUR+T10 guarantees a minimum reset timeout of 140ms after VCC rises above the 4.63V threshold, tested and specified across –40°C to +85°C. At +105°C, the timeout remains ≥100ms, ensuring μP initialization completes before release-even in thermally stressed environments like enclosed automotive enclosures.
Is the MAX810LEUR+T10 AEC-Q100 qualified and what grade does it meet?
Yes, the MAX810LEUR+T10 is AEC-Q100 qualified for Grade 2 (–40°C to +105°C), as confirmed in Maxim's official documentation. This qualification validates its suitability for automotive body electronics, infotainment power domains, and other under-hood applications requiring proven reliability and stress-test compliance.
