Product details
Overview
ADM1810-5AKS-REEL from Analog Devices is a precision microprocessor reset circuit with active-low push-pull output, 4.62 V typical reset threshold, 150 ms reset timeout, and SC70-3 package. It monitors 5 V power supplies in embedded controllers and industrial microprocessor systems to ensure safe power-up initialization.
For engineers reviewing the ADM1810-5AKS-REEL datasheet, ADM1810-5AKS-REEL pinout, ADM1810-5AKS-REEL application, or ADM1810-5AKS-REEL equivalent, key selection criteria include reset threshold accuracy (±1.5% over −40°C to +105°C), ultra-low quiescent current (9–16 µA), open-drain compatibility via internal pull-up, and guaranteed reset assertion during brownout conditions.
Technical Context
The ADM1810-5AKS-REEL integrates a precision voltage reference, comparator, and 150 ms monostable delay to generate a reliable active-low reset signal when VCC falls below 4.62 V (typ) or rises above it. Its push-pull output drives microprocessor reset inputs directly without external components.
Designed for high-reliability power sequencing, it features ±1.5% trip point tolerance over full temperature range, 10 µs fast response on supply fall, and guaranteed operation from 1.2 V to 5.5 V supply - enabling robust reset generation even during marginal power conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.62 V typical (4.50–4.75 V min/max); ensures reliable detection of 5 V supply undervoltage before system corruption. |
| Reset Timeout | 150 ms typical (100–250 ms); provides sufficient stabilization time for CPU, memory, and peripherals after power-up. |
| Supply Range | 1.2 V to 5.5 V; supports operation across wide input margins including degraded 5 V rails. |
| Quiescent Current | 9–16 µA at 5.5 V; enables battery-backed or low-power always-on monitoring without significant drain. |
| Output Type | Active-low push-pull; delivers rail-to-rail logic levels compatible with TTL/CMOS reset inputs without pull-up resistors. |
| Operating Temp | −40°C to +105°C; qualified for industrial and automotive under-hood environments. |
| Response Time | 10 µs on VCC fall; prevents spurious resets during fast transients while ensuring prompt fault capture. |
Pinout & Package
ADM1810-5AKS-REEL uses the 3-lead SC70 (KS-3) package - 2.00 mm × 1.25 mm × 0.95 mm body, 0.65 mm lead pitch - optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low reset output | Drives low during VCC < 4.62 V and remains low for 150 ms after VCC rises above threshold; directly interfaces with µP /CPLD reset pins. |
| VCC | Supply voltage input | Monitored 5 V rail input; also powers internal circuitry; operates down to 1.2 V for brownout immunity. |
| GND | Ground reference | 0 V return path for all internal biasing and output stage; must be low-impedance to avoid false resets. |
Key Features
| Feature | Design Value |
|---|---|
| Precision reset threshold | 4.62 V ±1.5% over −40°C to +105°C - eliminates need for external trimming in 5 V systems. |
| Guaranteed reset assertion | Asserts RST low for ≥150 ms on power-up and power-down - meets Intel-compatible reset timing requirements. |
| Ultra-low supply current | 9 µA min at 5.5 V - extends battery life in portable instrumentation and remote sensors. |
| Direct µP interface | Push-pull output sinks 8 mA and sources 350 µA - drives reset inputs without external pull-ups or level shifters. |
| Robust transient immunity | Rejects ≤10 µs glitches on VCC - prevents false resets during switching noise or ESD events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2T | 4.63 V threshold, 140 ms reset timeout, SOT-23-3 package, 20 µA max ICC | Higher quiescent current and tighter timeout tolerance; lacks extended temp rating (−40°C to +85°C only) | Prefer ADM1810-5AKS-REEL for industrial designs requiring full −40°C to +105°C operation and lower ICC. |
| TPS3808G33DBVR | 3.3 V fixed threshold, adjustable delay option, 1.5 µA ICC, SOT-23-6 | Not pin-compatible; requires external capacitor for delay tuning; designed for lower-voltage systems | Select ADM1810-5AKS-REEL when 4.62 V threshold and SC70 footprint are mandatory for legacy 5 V designs. |
Compared with MAX809TRD2T and TPS3808G33DBVR, the ADM1810-5AKS-REEL offers superior temperature stability (±1.5% vs. ±2.5%), lower supply current, and guaranteed 105°C operation - making it optimal for high-reliability 5 V microprocessor reset in constrained spaces.

FAQ
What is the exact reset threshold voltage of the ADM1810-5AKS-REEL?
The ADM1810-5AKS-REEL has a nominal reset threshold of 4.62 V, with a guaranteed range of 4.50 V (min) to 4.75 V (max) across −40°C to +105°C. This value is factory-trimmed and specified in Table 1 of the Rev. F datasheet, making it suitable for precise 5 V supply monitoring without external calibration.
Does the ADM1810-5AKS-REEL require an external pull-up resistor on the RST pin?
No, the ADM1810-5AKS-REEL does not require an external pull-up resistor because it features an active-low push-pull output stage. The RST pin actively drives low during reset and high otherwise - eliminating external components and ensuring clean, rail-to-rail logic transitions compatible with most microprocessor reset inputs.
Can the ADM1810-5AKS-REEL operate with supply voltages below 5 V?
Yes, the ADM1810-5AKS-REEL operates from 1.2 V to 5.5 V per Absolute Maximum Ratings and functional specifications. While its 4.62 V threshold targets 5 V systems, the device remains fully functional at lower VCC levels - enabling brownout detection and reset assertion even when the monitored rail collapses to 1.2 V.
What is the reset timeout duration of the ADM1810-5AKS-REEL, and is it adjustable?
The ADM1810-5AKS-REEL provides a fixed 150 ms typical reset timeout (100–250 ms min/max) after VCC rises above the threshold. This delay is internally generated and non-adjustable - ensuring consistent, predictable reset timing without external capacitors or configuration pins.
Is the ADM1810-5AKS-REEL RoHS compliant and halogen-free?
Yes, the ADM1810-5AKS-REEL is RoHS compliant (indicated by the "Z" suffix in alternate part numbers like ADM1810-5AKSZ-REEL) and manufactured to meet JEDEC J-STD-020 moisture sensitivity and halogen-free standards per Analog Devices' environmental policy.
