Product details
Overview
ADM810JAKSZ-REEL from Analog Devices is a microprocessor supervisory circuit in 3-lead SC70 package, providing active-high push-pull RESET output with 4.00 V reset threshold, 240 ms typical power-on reset timeout, operation down to 1.0 V VCC, and 17 μA supply current. It monitors supply voltage in embedded controllers and ensures reliable reset assertion during power-up, brownout, and power-down.
For engineers reviewing the ADM810JAKSZ-REEL datasheet, ADM810JAKSZ-REEL pinout, ADM810JAKSZ-REEL application, or ADM810JAKSZ-REEL equivalent, key selection criteria include reset polarity (active-high), SC70 package compatibility, −40°C to +125°C operating range, precise 4.00 V threshold tolerance, and low-power supervision for battery-backed or industrial control systems.
Technical Context
The ADM810JAKSZ-REEL integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timer. Its reference circuit maintains stable threshold detection across temperature (±30 ppm/°C), enabling robust operation even under fast VCC transients.
As a member of the ADM803/ADM809/ADM810 family, it shares architecture with push-pull output variants but differs from ADM803 (open-drain) and ADM809 (active-low push-pull). The J-suffix denotes 4.00 V threshold, validated for ADM809/ADM810 only per Table 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.00 V (typical at 25°C); holds microprocessor in reset until VCC rises above this level with ±0.10 V variation over −40°C to +125°C. |
| Reset Timeout | 240 ms (typical); ensures sufficient stabilization time before releasing reset, critical for flash programming and PLL lock sequences. |
| Supply Current | 17 μA (typical at VCC < 3.6 V, −40°C to +85°C); enables use in always-on, low-power monitoring circuits without significant battery drain. |
| VCC Operating Range | 1.0 V to 5.5 V; allows supervision of deeply undervolted rails and supports brownout detection down to 1 V before complete failure. |
| Output Type | Active-high push-pull; drives high without external pull-up, simplifying interface to CMOS inputs and eliminating resistor placement overhead. |
| Temperature Range | −40°C to +125°C; qualified for automotive under-hood, industrial motor control, and harsh-environment embedded applications. |
| Package | 3-lead SC70 (KS-3); 1.25 mm × 2.00 mm footprint with 0.65 mm pitch, suitable for space-constrained PCB layouts. |
Pinout & Package
ADM810JAKSZ-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) | Supply Input | Monitored voltage rail input; powers internal circuitry and must remain ≥1.0 V for functional reset assertion. |
| 2 (RESET) | Active-High Output | Push-pull logic output asserted high while VCC < 4.00 V; remains high for 240 ms after VCC exceeds threshold. |
| 3 (GND) | Ground Reference | Common return path for all internal functions; must be low-impedance to ensure accurate threshold comparison. |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune reset comparator | Rejects transients ≤100 µs duration at VTH – VCC ≥100 mV, preventing spurious resets during switching noise. |
| Precision threshold tolerance | ±0.10 V over full temperature range ensures deterministic reset point across environmental stress conditions. |
| Low-voltage operation | Functional reset assertion down to 1.0 V VCC enables early fault detection before system collapse. |
| High-temperature qualification | Specified from −40°C to +125°C with no derating, supporting automotive and industrial thermal profiles. |
| SC70 footprint compatibility | Same pinout and dimensions as other ADM8xx SC70 variants, allowing design reuse across threshold options. |
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 |
|---|---|---|---|
| ADM809JAKSZ-REEL | Identical 4.00 V threshold and SC70 package, but provides active-low RESET output instead of active-high. | Requires inverted logic handling in MCU reset input or external inverter; unsuitable where active-high native interface is mandatory. | Select when legacy design uses active-low reset or when interfacing to processors with dedicated active-low reset pins. |
| MAX809JUR-T | 4.00 V threshold, SOT-23-3 package, active-high push-pull output, but rated only to +85°C (vs. +125°C) and higher 25 μA typical supply current. | Limited to commercial/industrial ambient environments; not qualified for under-hood automotive or extended-temperature industrial use. | Choose for cost-sensitive, lower-temperature applications where 125°C operation is unnecessary and SOT-23 layout reuse is prioritized. |
Compared with ADM810JAKSZ-REEL, ADM809JAKSZ-REEL requires logic inversion for active-high systems, while MAX809JUR-T sacrifices temperature range and power efficiency for broader distributor availability - making ADM810JAKSZ-REEL optimal for high-reliability, thermally demanding designs requiring native active-high signaling.

FAQ
What is the reset polarity and output type of ADM810JAKSZ-REEL?
The ADM810JAKSZ-REEL features an active-high push-pull RESET output. Unlike the open-drain ADM803 or active-low ADM809 variants, ADM810JAKSZ-REEL drives the RESET pin high during reset assertion and low when released - eliminating need for external pull-up resistors and simplifying interface to standard CMOS inputs.
Does ADM810JAKSZ-REEL support operation below 2.5 V VCC?
Yes, ADM810JAKSZ-REEL remains fully functional down to 1.0 V VCC, including valid reset assertion and timing. This capability is explicitly specified in Table 1 and enables reliable brownout detection well before complete system failure - a key differentiator versus many competing supervisors limited to ≥2.5 V operation.
What is the guaranteed reset timeout duration for ADM810JAKSZ-REEL across temperature?
The ADM810JAKSZ-REEL guarantees a minimum reset timeout of 140 ms and maximum of 460 ms over −40°C to +85°C, with typical value of 240 ms. At elevated temperatures (85°C to 125°C), the timeout range expands to 100–840 ms per Table 1 - design margins must account for this variation in timing-critical applications.
Can ADM810JAKSZ-REEL be used in place of ADM809JAKSZ-REEL without hardware changes?
No - although both share identical 4.00 V threshold, SC70 package, and pinout, ADM810JAKSZ-REEL outputs active-high RESET while ADM809JAKSZ-REEL outputs active-low. Substituting one for the other without logic inversion will cause incorrect reset behavior; the devices are functionally complementary, not drop-in replacements.
What packaging and marking information identifies ADM810JAKSZ-REEL on the device?
ADM810JAKSZ-REEL is supplied in a 3-lead SC70 (KS-3) package with RoHS-compliant finish (Z suffix). The top-side marking is "M6V", and the bottom-side branding includes "XX" (date code) per Ordering Guide footnote 3 - verified in the official Analog Devices ordering table on Page 10 of Rev. I datasheet.
