Product details
Overview
ADM810SAKS-REEL7 from Analog Devices is a microprocessor supervisory circuit in 3-lead SC70 package, providing active-high push-pull RESET output with 2.93 V reset threshold, 240 ms typical power-on reset timeout, and operation down to 1.0 V VCC. It monitors supply voltage in embedded controllers and ensures reliable reset assertion during brownout and power-up.
For engineers reviewing the ADM810SAKS-REEL7 datasheet, ADM810SAKS-REEL7 pinout, ADM810SAKS-REEL7 application, or ADM810SAKS-REEL7 equivalent, key selection criteria include reset polarity (active-high), SC70 package footprint, 2.93 V threshold tolerance over −40°C to +125°C, and compatibility with 3 V microcontroller I/O levels.
Technical Context
The ADM810SAKS-REEL7 integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timer. Its reference circuit maintains ±1.5% threshold accuracy across temperature (−40°C to +125°C) and supports valid reset assertion even as VCC drops to 1.0 V.
Unlike open-drain variants, this device features a push-pull output capable of sourcing 150 μA at 1.8 V < VCC < VTH min, eliminating need for external pull-up resistors. The SC70 package enables high-density PCB layouts while maintaining thermal performance (θJA = 146°C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.93 V nominal, ±1.5% over −40°C to +125°C - ensures accurate 3 V rail monitoring without external calibration |
| Reset Timeout | 240 ms typical power-on delay - holds microprocessor in reset until supply stabilizes |
| Supply Range | 1.0 V to 5.5 V - supports operation during deep brownout and enables use with low-voltage logic |
| Output Type | Active-high push-pull - directly interfaces to CMOS inputs without pull-up resistor or level-shifting |
| Quiescent Current | 17 μA typical at VCC < 3.6 V - suitable for battery-powered and always-on monitoring applications |
| Temperature Range | −40°C to +125°C - qualified for automotive under-hood and industrial control environments |
| Package | 3-lead SC70 (KS-3) - 2.0 mm × 2.1 mm footprint, JEDEC-compliant, reflow-solderable |
Pinout & Package
ADM810SAKS-REEL7 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 - consistent with Figure 4 and Table 4 of Rev. I datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Monitored supply input - connects directly to 3 V rail; powers internal comparator and timer |
| 2 | RESET | Active-high push-pull output - drives high during normal operation, pulls low for 240 ms after power-up or brownout |
| 3 | GND | Ground reference - must be tied to system ground plane with low-inductance connection for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune reset comparator | Rejects transients ≤100 μs duration at VTH – VCC ≥ 100 mV - prevents false resets from supply noise |
| Low-VCC reset operation | Valid RESET assertion down to 1.0 V VCC - ensures fail-safe behavior during deep undervoltage |
| Precision threshold stability | 30 ppm/°C temperature coefficient - maintains 2.93 V trip point within ±1.5% over full temp range |
| Ultra-low power consumption | 17 μA typical supply current - extends battery life in portable instrumentation and sensor nodes |
| SC70 footprint compatibility | 2.0 mm × 2.1 mm body, 0.65 mm pin pitch - enables high-density placement on space-constrained PCBs |
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 |
|---|---|---|---|
| MAX809SSTR | 2.93 V threshold, SOT-23-3 package, 140 ms min reset timeout, open-drain output | Requires external pull-up resistor; shorter timeout may not meet 240 ms stabilization requirement for some MCUs | Select when board already uses SOT-23 footprint and pull-up exists; verify MCU reset timing margin. |
| TPS3801K33DBVR | 3.08 V threshold, SOT-23-3, 200 ms min reset timeout, push-pull output, 1.6 V min VCC | Higher threshold reduces noise margin on 3.3 V rail; lower VCC limit enables earlier reset release | Prefer for ultra-low-power systems needing reset at 1.6 V, but confirm 3.08 V trip aligns with system brownout spec. |
Compared with MAX809SSTR and TPS3801K33DBVR, ADM810SAKS-REEL7 provides exact 2.93 V trip with guaranteed 240 ms timeout and SC70 footprint - critical for designs requiring precise timing alignment and space-constrained layouts where SOT-23 is not viable.

FAQ
What is the reset threshold voltage of the ADM810SAKS-REEL7?
The ADM810SAKS-REEL7 has a nominal reset threshold of 2.93 V, with guaranteed tolerance of ±1.5% over the full operating temperature range (−40°C to +125°C). This value is confirmed in Table 3 and specifications for ADM8xxS models in the Rev. I datasheet, and applies specifically to the ADM810SAKS-REEL7 variant.
Does the ADM810SAKS-REEL7 require an external pull-up resistor?
No, the ADM810SAKS-REEL7 features a push-pull RESET output and does not require an external pull-up resistor. This is explicitly stated in the General Description and distinguishes it from the open-drain ADM803 family. The push-pull configuration allows direct interfacing with CMOS inputs across its full 1.0 V to 5.5 V supply range.
What is the power-on reset timeout duration for the ADM810SAKS-REEL7?
The ADM810SAKS-REEL7 provides a typical power-on reset timeout of 240 ms, with a minimum of 140 ms and maximum of 460 ms over −40°C to +85°C, as specified in the RESET ACTIVE TIMEOUT PERIOD parameter of Table 1. This ensures sufficient stabilization time for modern microcontrollers before releasing reset.
Which package type is used by the ADM810SAKS-REEL7?
The ADM810SAKS-REEL7 uses the 3-lead SC70 package (JEDEC KS-3), with dimensions of 2.0 mm × 2.1 mm and 0.65 mm pin pitch. This is confirmed in the Ordering Guide (Page 10) and Outline Dimensions (Figure 15) of the Rev. I datasheet, and is distinct from the SOT-23 option used by other ADM810 variants like ADM810SARTZ-REEL7.
Can the ADM810SAKS-REEL7 operate with supply voltages below 3 V?
Yes, the ADM810SAKS-REEL7 operates from 1.0 V to 5.5 V, and its RESET output remains functional down to 1.0 V VCC. This capability is documented in the VCC OPERATING VOLTAGE RANGE specification (Table 1) and General Description, enabling reliable reset assertion during deep brownout conditions common in battery-powered systems.
