Product details
Overview
ADM810MAKS-REEL7 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 and consumes only 17 μA at 3.6 V, targeting low-power embedded systems requiring reliable brownout detection.
For engineers reviewing the ADM810MAKS-REEL7 datasheet, ADM810MAKS-REEL7 pinout, ADM810MAKS-REEL7 application, or ADM810MAKS-REEL7 equivalent, key selection criteria include reset polarity (active-high), SC70-3 package compatibility, guaranteed operation across −40°C to +125°C, and precise 4.38 V threshold tolerance over temperature.
Technical Context
The ADM810MAKS-REEL7 integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timer. Its active-high push-pull RESET output drives directly into CMOS inputs without external pull-up components.
Voltage monitoring operates continuously from VCC = 1.0 V to 5.5 V, with threshold accuracy maintained across −40°C to +125°C (±0.05 V typical deviation). The device uses an internal bandgap reference and features 30 ppm/°C temperature coefficient for stable reset assertion during thermal transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.38 V ±0.05 V (−40°C to +125°C); ensures reliable reset assertion before 3.3 V system supply drops below functional minimum. |
| RESET Polarity & Type | Active-high push-pull; eliminates need for external pull-up resistor and guarantees defined logic level during full VCC range. |
| Power-On Reset Timeout | 240 ms typical; holds microprocessor in reset until power rail stabilizes post-power-up, preventing premature execution. |
| Supply Current | 17 μA typical at VCC < 3.6 V; enables integration into battery-powered or energy-constrained applications without significant quiescent load. |
| Operating Voltage Range | 1.0 V to 5.5 V; supports valid reset assertion even during deep brownout conditions where VCC falls below 2.0 V. |
| Temperature Range | −40°C to +125°C; qualified for automotive under-hood, industrial control, and extended-temperature embedded deployments. |
| Reset Output Drive | 0.3 V max low-level voltage at 1.2 mA sink; ensures solid logic-low state compatible with standard 3.3 V and 5 V CMOS inputs. |
Pinout & Package
ADM810MAKS-REEL7 is housed in a 3-lead SC70 (KS-3) package - 2.00 mm × 2.10 mm × 0.90 mm body, 0.65 mm lead pitch - optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Monitored supply input; powers internal circuitry and serves as reference for reset comparator and output stage. |
| 2 | RESET | Active-high push-pull output; asserts high when VCC < 4.38 V, remains high for 240 ms after VCC rises above threshold. |
| 3 | GND | Ground reference for all internal functions and output driver; must be connected to system ground plane for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune reset comparator | Rejects fast VCC transients up to 100 mV overdrive for ≤200 μs; prevents false resets during switching noise or ESD events. |
| Precision threshold stability | 30 ppm/°C tempco and ±0.05 V total variation over −40°C to +125°C; maintains accurate reset point across thermal cycling. |
| Low-voltage operation | Valid RESET assertion down to VCC = 1.0 V; enables brownout detection in systems with steep supply droop or ultra-low-VCC designs. |
| Push-pull active-high output | Direct CMOS-compatible drive without pull-up; reduces BOM count and eliminates weak-state uncertainty on reset line. |
| Extended temperature qualification | Specified and tested from −40°C to +125°C; meets AEC-Q100 stress requirements for automotive and harsh-environment use. |
Applications
| Industrial PLC Controller | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM809MAKS-REEL7 | Same 4.38 V threshold and SC70-3 package, but active-low push-pull RESET output. | Requires inverted reset logic handling in MCU firmware or external inverter; not drop-in for active-high designs. | Select only if system architecture expects active-low reset assertion and no redesign of reset signal routing is feasible. |
| TPS3808G33DBVR | 3.3 V fixed threshold, 200 ms reset timeout, 1.8–6.0 V VCC range, SOT-23-5 package with manual reset input. | Includes manual reset pin and tighter 1.5% threshold accuracy, but larger 5-pin footprint and different timing profile. | Prefer when manual reset capability or higher threshold precision is required; avoid if SC70-3 size or exact 240 ms timeout is mandatory. |
Compared with ADM809MAKS-REEL7, ADM810MAKS-REEL7 eliminates external inversion logic; compared with TPS3808G33DBVR, it offers smaller SC70-3 footprint and longer guaranteed reset hold time, at the cost of no manual reset function.

FAQ
What is the reset polarity and output type of ADM810MAKS-REEL7?
The ADM810MAKS-REEL7 features an active-high push-pull RESET output. Unlike open-drain variants, it does not require an external pull-up resistor and actively drives both logic high and low states. This ensures clean, noise-immune reset signaling directly compatible with standard CMOS inputs across its full 1.0 V to 5.5 V operating range.
Does ADM810MAKS-REEL7 support operation at temperatures beyond 85°C?
Yes, ADM810MAKS-REEL7 is fully specified and tested from −40°C to +125°C. Its reset threshold remains within ±0.05 V of 4.38 V across this full range, and the 240 ms power-on reset timeout is guaranteed at all temperatures. This makes ADM810MAKS-REEL7 suitable for under-hood automotive, industrial motor drives, and outdoor infrastructure applications.
Can ADM810MAKS-REEL7 monitor a 3.3 V supply rail reliably?
Yes - the 4.38 V reset threshold of ADM810MAKS-REEL7 is specifically designed to supervise 5 V rails, but it also provides robust margin for 3.3 V systems with high ripple or slow regulation. When used with a 3.3 V supply, the device will assert RESET if VCC drops below ~4.33 V, which typically occurs only during severe brownout or fault conditions, offering fail-safe protection without nuisance triggering.
What is the minimum VCC required for ADM810MAKS-REEL7 to maintain valid RESET output?
ADM810MAKS-REEL7 guarantees valid RESET output down to VCC = 1.0 V. Below this, the internal circuitry ceases to operate, but the output remains in its last asserted state (high) until VCC collapses further. This 1.0 V lower limit enables reliable detection of deep brownouts where other supervisors may release reset prematurely.
Is ADM810MAKS-REEL7 RoHS compliant and halogen-free?
Yes, ADM810MAKS-REEL7 is a RoHS-compliant part (denoted by "Z" suffix in ordering code per Analog Devices' ordering guide) and meets JEDEC J-STD-609 moisture sensitivity and halogen-free requirements. The "Z" in the full part number confirms compliance with EU RoHS Directive 2011/65/EU and related restrictions on hazardous substances.
