Product details
Overview
MAX810MEUR+T from Maxim Integrated is a 3-pin SOT23-packaged microprocessor supervisory circuit with push-pull active-high RESET output, precision 4.38V reset threshold (±0.07V over −40°C to +105°C), 140ms minimum reset timeout, 12μA supply current at +25°C, and guaranteed operation down to VCC = 1V - used for reliable power-on/brownout reset assertion in embedded μP systems.
For engineers reviewing the MAX810MEUR+T datasheet, MAX810MEUR+T pinout, MAX810MEUR+T application, or MAX810MEUR+T equivalent, this page delivers verified electrical specs, package-confirmed pin functions, real-world use scenarios, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The MAX810MEUR+T implements a precision voltage comparator with temperature-compensated reference (30ppm/°C tempco) to monitor VCC against a fixed 4.38V threshold. Its push-pull output drives high during reset assertion and transitions low after VCC exceeds threshold plus hysteresis, with guaranteed logic-state validity down to VCC = 1V.
It features built-in immunity to fast VCC transients (e.g., ≤20μs glitches at 100mV overdrive do not trigger false resets) and requires no external components. The device operates across −40°C to +105°C and supports 1.2V to 5.5V VCC range, making it suitable for industrial-grade 5V systems with strict reliability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.38V ±0.07V (−40°C to +105°C); ensures reset asserts before 5V supply drops below 4.31V, preventing μP execution errors |
| Reset Timeout | 140ms min (−40°C to +85°C); guarantees sufficient hold time for μP initialization after power-up or brownout recovery |
| Supply Current | 17μA typ at +25°C (VCC = 3.6V); enables battery-powered operation with minimal quiescent drain |
| Output Type | Push-pull active-high RESET; eliminates need for external pullup and directly interfaces with CMOS inputs requiring high-asserted reset |
| VCC Operating Range | 1.2V to 5.5V; supports valid reset assertion even during deep brownout conditions down to 1.2V |
| Reset Validity | Guaranteed to VCC = 1V; RESET remains logically valid as supply collapses, avoiding floating states in critical shutdown sequences |
| Transient Immunity | Rejects ≤20μs negative VCC glitches at 100mV overdrive; prevents spurious resets from noise or switching transients |
Pinout & Package
MAX810MEUR+T is housed in 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 (push-pull, active-high), Pin 3 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Ground reference | Return path for internal comparator and output stage; must be low-impedance connection to system ground plane |
| RESET (Pin 2) | Active-high reset output | Drives high during reset condition (VCC < 4.38V) and low after timeout; sinks/source up to 3.2mA/500µA per spec |
| VCC (Pin 3) | Supply input | Power source for internal circuitry; also monitored voltage; bypass capacitor (0.1µF) required at pin for transient immunity |
Key Features
| Feature | Design Value |
|---|---|
| Precision 4.38V threshold | Enables deterministic reset timing in +5V systems without calibration or trimming components |
| 140ms minimum reset pulse width | Meets μP reset hold-time requirements across full temperature range without external RC timing |
| 12μA typical supply current | Extends battery life in portable instrumentation and remote sensors where standby power is constrained |
| Valid RESET to VCC = 1V | Ensures controlled shutdown sequence integrity when main supply decays below logic thresholds |
| 30ppm/°C threshold tempco | Maintains tight reset window across industrial temperature range, reducing design margin uncertainty |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809MEUR+T | Same 4.38V threshold and SOT23 package, but active-low push-pull RESET output | Requires redesign of reset logic polarity (e.g., inverter or μP with active-low reset input) | Select when system architecture mandates active-low reset signaling and board layout allows polarity change |
| TPS3808G18DBVR | 4.2V threshold (±0.5%), 350ms reset timeout, 1.8V–6.5V VCC range, different pinout (GND/EN/RESET) | Not pin-compatible; requires PCB modification; offers enable input for manual reset control | Choose when longer reset timeout or external reset initiation capability is needed, and layout revision is acceptable |
Compared with MAX809MEUR+T, the MAX810MEUR+T provides active-high reset without polarity inversion, simplifying interface to μPs with active-high reset pins; versus TPS3808G18DBVR, it offers tighter threshold accuracy (±0.07V vs ±0.5%) and smaller footprint, but lacks enable functionality and has shorter timeout.

FAQ
What is the reset threshold voltage of the MAX810MEUR+T and how does it vary with temperature?
The MAX810MEUR+T has a nominal reset threshold of 4.38V, with tolerance of ±0.07V over the full operating temperature range of −40°C to +105°C. Its temperature coefficient is specified at 30ppm/°C, meaning threshold drift is bounded and predictable - for example, maximum deviation is ±0.036V over a 120°C span. This precision ensures consistent reset behavior in industrial environments without external calibration.
Does the MAX810MEUR+T require an external pullup resistor on its RESET pin?
No, the MAX810MEUR+T does not require an external pullup resistor because it features a push-pull active-high RESET output. Unlike open-drain variants (e.g., MAX803), this device actively drives both high and low states. The RESET pin sources up to 500µA when high and sinks up to 3.2mA when low, enabling direct connection to standard CMOS inputs without additional components.
What is the minimum VCC voltage at which the MAX810MEUR+T guarantees correct RESET logic state?
The MAX810MEUR+T guarantees correct RESET logic state down to VCC = 1V. Below this level, the output may become indeterminate. This specification ensures that the active-high RESET signal remains valid throughout most of the supply collapse phase - critical for orderly shutdown in battery-backed or brownout-prone systems. For operation below 1V, external pull-down is recommended per Maxim's application note.
Is the MAX810MEUR+T AEC-Q100 qualified and what grade does it meet?
Yes, the MAX810MEUR+T is AEC-Q100 qualified. As indicated in the official datasheet's "Benefits and Features" section and ordering information, it meets AEC-Q100 Grade 2 standards (−40°C to +105°C), confirming suitability for automotive body electronics and non-safety-critical control modules. The "/V" suffix denotes automotive qualification, and MAX810MEUR+T falls under this category per Maxim's ordering guide.
Can the MAX810MEUR+T be used with 3.3V or 2.5V supply rails?
Yes, the MAX810MEUR+T supports VCC from 1.2V to 5.5V, but its 4.38V reset threshold makes it intended primarily for +5V systems. When used with 3.3V or 2.5V rails, the device will assert reset continuously since VCC never reaches the threshold - rendering it nonfunctional for those voltages. For 3.3V systems, select MAX810TEUR+T (3.08V threshold); for 2.5V, use MAX810REUR+T (2.63V) or MAX810SEUR+T (2.93V).
