Product details
Overview
ADM810RART-REEL from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 2.63 V reset threshold, and operation down to 1.0 V VCC. It provides 240 ms (typical) power-on reset timeout, consumes only 17 μA at 3.6 V, and is qualified for −40°C to +125°C industrial/automotive environments. It monitors 3 V supply rails in embedded controllers and intelligent instruments.
For engineers reviewing the ADM810RART-REEL datasheet, ADM810RART-REEL pinout, ADM810RART-REEL application, or ADM810RART-REEL equivalent, key selection factors include active-high push-pull drive capability, guaranteed reset assertion below 1 V VCC, ±1.5% threshold accuracy over temperature, and SOT-23-3 package compatibility with space-constrained PCB layouts.
Technical Context
The ADM810RART-REEL integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timer. Its reference circuit maintains stable threshold performance across −40°C to +125°C, with 30 ppm/°C temperature coefficient.
It features a push-pull RESET output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min), and sinking 1.2 mA at VCC = VTH(min). The device remains functional with VCC as low as 1.0 V, enabling reliable brownout detection before full system shutdown.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809RTRG+T | 2.63 V threshold, open-drain active-low RESET, 1.2 μA max supply current, −40°C to +125°C | Requires external pull-up; incompatible with active-high reset input pins without inversion logic | Select when lowest possible quiescent current is critical and system design accommodates active-low signaling. |
| TPS3808G12QDBVRQ1 | 1.22 V threshold (not 2.63 V), adjustable via external resistor, 1.8 μA typical IQ, AEC-Q100 Grade 1 | Not a direct threshold match; requires redesign of sensing network to achieve 2.63 V trip point | Choose only if programmability and automotive qualification outweigh fixed-threshold convenience and board space savings. |

FAQ
What is the reset threshold voltage of the ADM810RART-REEL?
The ADM810RART-REEL has a nominal reset threshold voltage of 2.63 V, with ±1.5% accuracy over the full −40°C to +125°C temperature range. This value is factory-trimmed and specified in Table 3 of the ADM803/ADM809/ADM810 datasheet Rev. I. The ADM810RART-REEL uses this precise threshold to monitor 3 V supply rails and assert RESET when VCC drops below the trip point.
Does the ADM810RART-REEL have an active-high or active-low reset output?
The ADM810RART-REEL features an active-high push-pull RESET output, meaning RESET goes high during normal operation and is driven low for 240 ms (typical) after power-up or brownout recovery. This distinguishes it from the ADM803 (open-drain active-low) and ADM809 (push-pull active-low). The ADM810RART-REEL requires no external pull-up resistor and directly drives high-true reset inputs on modern microcontrollers.
What package type is used for the ADM810RART-REEL?
The ADM810RART-REEL is packaged in a 3-lead SOT-23 (JEDEC RT-3) outline, with dimensions of 2.90 mm × 1.30 mm × 1.02 mm. This compact surface-mount package supports automated assembly and is pin-compatible with other SOT-23 supervisory ICs. The ADM810RART-REEL does not use SC70 packaging-only ADM810 variants with "KS-3" in the ordering guide carry SC70.
What is the minimum supply voltage at which the ADM810RART-REEL remains functional?
The ADM810RART-REEL guarantees reset assertion functionality down to 1.0 V VCC, as confirmed in the Absolute Maximum Ratings table and General Description section of the datasheet. Below 1.0 V, the internal circuitry ceases to operate reliably. This 1.0 V minimum enables the ADM810RART-REEL to detect deep brownout conditions that would otherwise leave the host microcontroller in an undefined state.
How does the ADM810RART-REEL handle power supply transients?
The ADM810RART-REEL incorporates a glitch-immune reset comparator that rejects fast transients on VCC. According to Figure 11 in the datasheet, it tolerates transients up to 100 mV overdrive for durations under ~100 μs without generating spurious reset pulses. This immunity prevents false resets caused by switching noise or EMI, ensuring robust operation in electrically noisy environments like automotive or industrial settings where the ADM810RART-REEL is commonly deployed.
