Product details
Overview
ADM810MAKSZ-REEL from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 4.38 V reset threshold, and operation down to 1.0 V VCC. It provides 240 ms (typical) power-on reset timeout, consumes 17 μA typical supply current, and is qualified for −40°C to +125°C industrial/automotive environments. It monitors 4.38 V supply rails in embedded controllers and portable instrumentation.
For engineers reviewing the ADM810MAKSZ-REEL datasheet, ADM810MAKSZ-REEL pinout, ADM810MAKSZ-REEL application, or ADM810MAKSZ-REEL equivalent, key selection criteria include reset polarity (active-high), SC70-3 package compatibility, guaranteed operation at VCC ≥ 1.0 V, and temperature-stable 4.38 V threshold with ±3.5% variation over −40°C to +125°C.
Technical Context
The ADM810MAKSZ-REEL integrates a precision voltage comparator with internal reference and a 240 ms reset timer. Its active-high push-pull RESET output drives directly into CMOS inputs without external pull-up components, unlike open-drain variants.
It operates across full VCC range of 1.0 V to 5.5 V and maintains reset assertion during brownout conditions until VCC rises above 4.38 V (±3.5%) and remains asserted for minimum 140 ms after threshold crossing. Glitch immunity prevents false resets from fast transients on VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.38 V nominal; ensures reliable reset assertion for 4.38 V supply monitoring with ±3.5% tolerance over −40°C to +125°C. |
| Reset Polarity | Active-high; eliminates need for external inverter or pull-up resistor when interfacing with microprocessors requiring high-asserted reset. |
| Reset Timeout | 240 ms typical; holds processor in reset long enough for power supply stabilization and clock circuit initialization. |
| Supply Current | 17 μA typical at VCC < 3.6 V; enables use in battery-powered systems with minimal quiescent load. |
| VCC Operating Range | 1.0 V to 5.5 V; supports valid reset generation even during deep brownout or low-voltage startup sequences. |
| Output Type | Push-pull; delivers rail-to-rail logic levels (0.3 V low / 0.8×VCC high) without external components. |
| Package | 3-lead SC70 (KS-3); 2.0 mm × 2.1 mm footprint compatible with space-constrained PCB layouts. |
Pinout & Package
ADM810MAKSZ-REEL uses a 3-lead SC70 (KS-3) package with exposed pad not electrically connected. Pin 1 = VCC, Pin 2 = RESET (active-high push-pull), Pin 3 = GND - confirmed per Figure 4 and Table 4 of Rev. I datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Monitored supply input; powers internal circuitry and defines logic high level for RESET output. |
| 2 | RESET | Active-high push-pull output; asserts high during reset condition and deasserts low when VCC exceeds 4.38 V. |
| 3 | GND | Ground reference for all internal comparators, timer, and output stage; must be low-impedance connection. |
Key Features
| Feature | Design Value |
|---|---|
| Precision reset threshold | 4.38 V with ±3.5% max deviation over −40°C to +125°C ensures accurate supply monitoring without calibration. |
| Low-power operation | 17 μA typical supply current extends battery life in portable and energy-sensitive applications. |
| Brownout detection | Valid reset assertion down to VCC = 1.0 V prevents premature processor release during undervoltage events. |
| Glitch-immune comparator | Immunity to transients ≤ 100 µs duration at VTH – VCC ≥ 100 mV avoids spurious resets in noisy environments. |
| SC70-3 footprint | 2.0 mm × 2.1 mm body size enables high-density placement in compact embedded systems. |
Applications
| Industrial PLC Controllers | Automotive Body Control Modules |
|---|---|
Use Scenario: Monitors 4.38 V auxiliary supply powering MCU and CAN transceivers in under-hood ECUs. IC Role / Device Role / Timing Role: Supervisory circuit asserting active-high reset during cold-crank voltage sag below 4.38 V. Use Value: Ensures deterministic MCU restart after battery recovery, with 240 ms timeout preventing race conditions during regulator settling. |
Use Scenario: Validates stable 4.38 V rail for infotainment SoC power domain before boot sequence initiation. IC Role / Device Role / Timing Role: Voltage monitor generating active-high reset pulse synchronized to power-good timing. Use Value: Eliminates need for external level-shifting or pull-up resistors due to push-pull output driving 1.8 V/3.3 V logic directly. |
| Portable Medical Sensors | Smart Energy Meters |
Use Scenario: Supervises coin-cell–powered 4.38 V LDO output feeding ultra-low-power microcontroller. IC Role / Device Role / Timing Role: Low-current (17 μA) supervisor maintaining reset until battery voltage recovers post-deep discharge. Use Value: Enables reliable wake-from-reset behavior with guaranteed operation down to 1.0 V VCC during brownout. |
Use Scenario: Monitors 4.38 V isolated DC-DC output powering metrology ADC and real-time clock. IC Role / Device Role / Timing Role: Precision voltage detector ensuring meter firmware initializes only after stable supply is confirmed. Use Value: Prevents corrupted EEPROM writes or incorrect timekeeping by enforcing 240 ms minimum reset hold time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM809MAKSZ-REEL7 | Same 4.38 V threshold and SC70-3 package, but active-low push-pull RESET output. | Requires redesign of reset signal routing if host MCU expects active-high assertion. | Select when legacy board design already uses active-low reset logic and no inverter is available. |
| TPS3808G18DBVR | 4.2 V threshold (not 4.38 V), 350 ms min reset timeout, 1.8 V to 6.0 V VCC range, SOT-23-5 package. | Higher threshold tolerance (±0.5% vs ±3.5%), longer timeout, and extra enable pin add complexity for simple 4.38 V monitoring. | Choose only if tighter threshold accuracy or adjustable timeout is required; otherwise, ADM810MAKSZ-REEL offers better fit. |
Compared with ADM809MAKSZ-REEL7, ADM810MAKSZ-REEL avoids level inversion hardware; compared with TPS3808G18DBVR, it delivers exact 4.38 V trip point in smaller SC70-3 footprint with lower quiescent current-making it optimal for cost- and space-constrained 4.38 V rail supervision.

FAQ
What is the reset threshold voltage of the ADM810MAKSZ-REEL?
The ADM810MAKSZ-REEL has a nominal reset threshold of 4.38 V, with guaranteed tolerance of ±3.5% over the full operating temperature range of −40°C to +125°C. This value is specified in Table 3 and validated in Table 1 of the Rev. I datasheet for the "M" grade variant.
Does the ADM810MAKSZ-REEL have an active-high or active-low reset output?
The ADM810MAKSZ-REEL features an active-high push-pull RESET output, meaning the pin drives high during reset assertion and low when deasserted. This distinguishes it from the ADM803 (open-drain active-low) and ADM809 (push-pull active-low) variants in the same family.
What package type is used for the ADM810MAKSZ-REEL?
The ADM810MAKSZ-REEL is packaged in a 3-lead SC70 (KS-3) outline, measuring 2.0 mm × 2.1 mm with 0.65 mm lead pitch. This is confirmed in the Ordering Guide (page 10) and Outline Dimensions (Figure 15) of the Rev. I datasheet.
Can the ADM810MAKSZ-REEL operate with supply voltages below 2.5 V?
Yes - the ADM810MAKSZ-REEL operates with VCC as low as 1.0 V while still asserting RESET, enabling robust brownout detection even during severe undervoltage conditions. Its functional VCC range is 1.0 V to 5.5 V, per Table 1 in the datasheet.
What is the typical reset timeout duration for the ADM810MAKSZ-REEL?
The ADM810MAKSZ-REEL provides a typical reset timeout of 240 ms after VCC rises above the 4.38 V threshold. The datasheet specifies a minimum of 140 ms and maximum of 460 ms over −40°C to +85°C, and 100 ms to 840 ms over +85°C to +125°C.
