Product details
Overview
ADM13307-33ARZ from Analog Devices is a triple voltage supervisor IC designed to monitor three independent supply rails-5 V, 3.3 V, and an externally adjustable 1.25 V reference-in microprocessor and DSP systems. It features push-pull active-high and active-low RESET outputs, 140 ms minimum reset timeout, 40 μA max supply current, and operates from 2.0 V to 5.5 V over −40°C to +85°C.
For engineers reviewing the ADM13307-33ARZ datasheet, ADM13307-33ARZ pinout, ADM13307-33ARZ application, or ADM13307-33ARZ equivalent, key selection considerations include its fixed 4.55 V / 2.93 V / 1.25 V threshold configuration, SOIC_N-8 package, manual reset (MR) support, and guaranteed RESET assertion down to VDD ≥ 1.1 V.
Technical Context
The ADM13307-33ARZ implements three independent undervoltage detection channels with pretrimmed thresholds: SENSE1 monitors 5 V (VIT− = 4.55 V typ), SENSE2 monitors 3.3 V (VIT− = 2.93 V typ), and SENSE3 supports adjustable monitoring via external resistor divider referenced to 1.25 V. Each channel includes hysteresis (30 mV at 2.93 V, 40 mV at 4.55 V) and glitch immunity.
It integrates a reset timer with 140–280 ms timeout, dual push-pull RESET outputs (active-low RESET and active-high RESET), and a manual reset input (MR) that asserts reset for the full timeout period upon low-going edge. Power-up reset activation begins at VDD ≥ 1.1 V, ensuring early system supervision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - Supports wide-input industrial and embedded power rails without external regulation. |
| SENSE1 Threshold (VIT−) | 4.46 V to 4.67 V - Monitors 5 V supply with ±2.5% tolerance across temperature; hysteresis = 40 mV. |
| SENSE2 Threshold (VIT−) | 2.86 V to 3.02 V - Monitors 3.3 V supply with ±2.5% tolerance; hysteresis = 30 mV. |
| SENSE3 Reference | 1.25 V internal reference - Enables precise external resistor-divider programming for custom voltage monitoring. |
| Reset Timeout | 140 ms (min) to 280 ms (max) - Ensures reliable processor initialization before release; programmable via external capacitor not supported. |
| Supply Current | 40 μA max - Ultra-low quiescent current enables use in battery-backed or always-on supervision circuits. |
| Operating Temperature | −40°C to +85°C - Qualified for extended industrial environments without derating. |
Pinout & Package
ADM13307-33ARZ is housed in an 8-lead narrow-body SOIC (SOIC_N, JEDEC MS-012-AA, package code R-8), 3.9 mm × 4.9 mm body size, 1.27 mm lead pitch, with gull-wing leads and RoHS-compliant finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - SENSE1 | Voltage sense input 1 | Monitors 5 V rail (4.55 V nominal threshold); requires no external components for fixed-threshold operation. |
| 2 - SENSE2 | Voltage sense input 2 | Monitors 3.3 V rail (2.93 V nominal threshold); internally trimmed, no calibration needed. |
| 3 - SENSE3 | Voltage sense input 3 | Adjustable threshold via 1.25 V reference; external resistor divider sets monitored voltage (e.g., 12 V, 15 V). |
| 4 - GND | Ground reference | Common return for all analog and digital circuitry; must be low-impedance connection to system ground plane. |
| 5 - RESET | Active-low push-pull reset output | Drives microcontroller /DSP reset pin directly; sinks up to 5 mA; valid down to VDD = 1.1 V. |
| 6 - RESET | Active-high push-pull reset output | Provides complementary signal for logic-level interface or OR-ing with other reset sources. |
| 7 - MR | Manual reset input | Active-low; debounced by internal timer; initiates full reset timeout when pulled low (e.g., via push button). |
| 8 - VDD | Power supply input | Accepts 2.0–5.5 V; decoupling with 0.1 μF ceramic capacitor to GND required for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent voltage supervision | Simultaneously monitors 5 V, 3.3 V, and user-defined rail - eliminates need for multiple discrete supervisors. |
| Dual push-pull RESET outputs | Both active-high and active-low signals available - simplifies interface to diverse processor reset architectures. |
| Guaranteed reset at low VDD | RESET asserted reliably down to VDD = 1.1 V - ensures supervision during brown-out and power ramp-up. |
| Adjustable third threshold (1.25 V ref) | Enables monitoring of any voltage >1.25 V using two-resistor divider - extends applicability beyond standard rails. |
| 140 ms minimum reset timeout | Meets typical microprocessor power-on reset timing requirements without external timing components. |
| −40°C to +85°C operation | Validated performance across full industrial temperature range - suitable for uncontrolled ambient deployments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326–33D | Single 3.3 V supervisor with manual reset; no triple-monitoring or adjustable reference. | Only monitors one rail; requires additional ICs for full 3-rail coverage. | Select only if supervising a single 3.3 V supply with minimal BOM count priority. |
| TPS3808G33 | Single-channel 3.3 V supervisor with 200 ms timeout; no SENSE2/SENSE3 inputs or dual RESET outputs. | Lacks multi-rail capability and complementary reset signaling; no 1.25 V reference for adjustable monitoring. | Use when only 3.3 V rail supervision is required and PCB space is extremely constrained. |
Compared with MAX6326–33D and TPS3808G33, the ADM13307-33ARZ uniquely delivers integrated triple-rail supervision, dual active-reset outputs, and a programmable third channel - reducing component count, interconnect complexity, and validation effort in multi-supply systems.

FAQ
What voltage rails does the ADM13307-33ARZ monitor by default?
The ADM13307-33ARZ monitors three rails: SENSE1 is factory-trimmed to 4.55 V (for 5 V systems), SENSE2 to 2.93 V (for 3.3 V systems), and SENSE3 uses the internal 1.25 V reference to support user-defined thresholds via external resistor divider. This configuration is fixed per the ADM13307-33 variant and cannot be altered post-manufacture.
Does the ADM13307-33ARZ require external timing components for reset timeout?
No, the ADM13307-33ARZ includes an internal oscillator and timer that guarantee a minimum 140 ms reset timeout - no external capacitor or resistor is needed. The timeout is fixed and non-adjustable, simplifying design and improving repeatability across units and temperature.
Can the ADM13307-33ARZ operate with a 2.0 V supply?
Yes, the ADM13307-33ARZ operates across 2.0 V to 5.5 V. Its RESET outputs remain functional down to VDD = 1.1 V, and all supervision functions (including SENSE input comparators and logic) are fully specified from 2.0 V. At 2.0 V, SENSE thresholds scale proportionally per datasheet tolerances.
How is the adjustable SENSE3 input configured for monitoring a 12 V rail?
To monitor 12 V with SENSE3, connect a resistor divider such that the voltage at SENSE3 equals 1.25 V when the 12 V rail is nominal. For example: R1 = 8.6 kΩ (between 12 V and SENSE3), R2 = 1.0 kΩ (between SENSE3 and GND). This yields 12 V × [1.0 / (8.6 + 1.0)] ≈ 1.25 V. Divider current should stay below 10 μA.
Is the ADM13307-33ARZ pin-compatible with other ADM13307 variants?
Yes, all ADM13307 variants - including ADM13307-18ARZ, ADM13307-25ARZ, and ADM13307-33ARZ - share identical 8-lead SOIC_N (R-8) pinout and electrical interface. Only the internal threshold configurations differ; PCB layout and firmware integration remain unchanged across variants.
