Product details
Overview
ADM13307-33ARZ-RL7 from Analog Devices is a triple voltage supervisor IC designed to monitor 4.55 V, 2.93 V, and 1.25 V supply rails in microprocessor and DSP systems. It features push-pull active-high and active-low RESET outputs, 140 ms minimum reset timeout, operation from 2.0 V to 5.5 V VDD, and −40°C to +85°C temperature range. Used for reliable power-on reset and brownout detection in embedded control applications.
For engineers reviewing the ADM13307-33ARZ-RL7 datasheet, ADM13307-33ARZ-RL7 pinout, ADM13307-33ARZ-RL7 application, or ADM13307-33ARZ-RL7 equivalent, key selection criteria include fixed dual-threshold configuration (4.55 V / 2.93 V), externally adjustable 1.25 V reference input, guaranteed RESET assertion down to VDD ≥ 1.1 V, and SOIC_N package compatibility with industrial-grade thermal performance.
Technical Context
The ADM13307-33ARZ-RL7 implements three independent undervoltage monitoring channels with pretrimmed internal thresholds at 4.55 V (SENSE1) and 2.93 V (SENSE2), plus one adjustable channel referenced to 1.25 V (SENSE3). Each SENSEv input includes hysteresis-40 mV at 4.55 V, 30 mV at 2.93 V, and 40 mV at 1.25 V-to prevent chatter during threshold crossings.
It uses an internal oscillator-based timer to enforce a minimum 140 ms reset timeout after all monitored supplies exceed their rising thresholds. The device asserts both RESET (active low) and RESET (active high) simultaneously, with push-pull output stages capable of sourcing up to 5 mA and sinking up to 5 mA, ensuring robust interface with diverse logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 2.0 V to 5.5 V - supports wide-input industrial and mixed-rail systems without external regulation. |
| SENSE1 Threshold | 4.55 V (typ), ±0.09 V - factory-trimmed for accurate 5 V rail supervision with 40 mV hysteresis. |
| SENSE2 Threshold | 2.93 V (typ), ±0.07 V - factory-trimmed for precise 3.3 V rail monitoring with 30 mV hysteresis. |
| SENSE3 Reference | 1.25 V (fixed internal reference) - enables external resistor-divider programming for custom voltage monitoring. |
| Reset Timeout | 140 ms (min), 200 ms (typ), 280 ms (max) - ensures sufficient processor initialization time after stable power-up. |
| Supply Current | 40 μA (max) - ultra-low quiescent current preserves battery life in portable and always-on systems. |
| RESET Valid Voltage | VDD ≥ 1.1 V - guarantees functional reset assertion during early power ramp-up before full VDD stabilization. |
Pinout & Package
ADM13307-33ARZ-RL7 is housed in an 8-lead narrow-body SOIC (SOIC_N, JEDEC MS-012-AA, package code R-8), with 1.27 mm lead pitch and thermal resistance θJA = 206°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - SENSE1 | Fixed-threshold voltage monitor input | Monitors 4.55 V nominal supply; asserts reset if voltage falls below 4.46–4.67 V (−40°C to +85°C). |
| 2 - SENSE2 | Fixed-threshold voltage monitor input | Monitors 2.93 V nominal supply; asserts reset if voltage falls below 2.86–3.02 V (−40°C to +85°C). |
| 3 - SENSE3 | Adjustable-threshold reference input | Accepts resistor-divider network referenced to internal 1.25 V; enables custom voltage supervision. |
| 4 - GND | Power ground reference | Common return path for VDD, SENSEv inputs, MR, and RESET outputs; requires low-impedance PCB connection. |
| 5 - RESET | Active-low push-pull reset output | Drives low during reset condition; sinks up to 5 mA; compatible with TTL/CMOS inputs requiring active-low reset. |
| 6 - RESET | Active-high push-pull reset output | Drives high during reset condition; sources up to 5 mA; interfaces directly with processors needing active-high reset. |
| 7 - MR | Manual reset input | Active-low asynchronous trigger; initiates reset when pulled ≤ 0.3 × VDD; debounced via internal timing. |
| 8 - VDD | Supply voltage input | Primary power rail (2.0–5.5 V); powers internal comparators, timer, and output drivers; requires 0.1 μF bypass capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent voltage monitoring | Simultaneously supervises three distinct supply rails-eliminates need for multiple discrete supervisors and reduces BOM count. |
| Dual fixed + one adjustable threshold | 4.55 V and 2.93 V thresholds are factory-trimmed for accuracy; 1.25 V reference allows flexible customization for non-standard rails. |
| Guaranteed RESET at low VDD | RESET outputs remain valid and functional down to VDD = 1.1 V-ensures reliable reset assertion during brownout and startup. |
| Push-pull RESET and RESET outputs | No external pull-up/pull-down required; drives both logic polarities directly-simplifies interface with diverse host processors and FPGAs. |
| 140 ms minimum reset timeout | Internally timed delay prevents premature release of reset before system clocks and memory stabilize post-power-up. |
Applications
| Industrial PLC Controller | Wireless Baseband Processor |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6832EUT+T | Single 3.3 V supervisor with manual reset; no triple monitoring or adjustable reference. | Suitable only for single-rail systems; lacks SENSE2/SENSE3 flexibility and coordinated timeout. | Select only when supervising one rail and cost sensitivity outweighs feature requirements. |
| TPS3808G33DBVR | Single 3.3 V supervisor with 200 ms timeout and 1.8 V to 5.5 V VDD; no multi-rail capability or dual RESET outputs. | Requires two additional supervisors to match ADM13307-33ARZ-RL7's triple-channel function. | Prefer for space-constrained single-rail designs where footprint is prioritized over integration. |

FAQ
What voltage rails does the ADM13307-33ARZ-RL7 monitor?
The ADM13307-33ARZ-RL7 monitors three voltage 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 an internal 1.25 V reference to support externally programmed thresholds via resistor dividers. This configuration is explicitly defined in the Ordering Guide for the ADM13307-33 variant.
Does the ADM13307-33ARZ-RL7 provide both active-high and active-low reset outputs?
Yes, the ADM13307-33ARZ-RL7 features two independent push-pull reset outputs: pin 5 (RESET) is active low, and pin 6 (RESET) is active high. Both outputs assert and deassert simultaneously, eliminating the need for external inverters or level shifters when interfacing with processors requiring either polarity.
What is the minimum VDD voltage at which ADM13307-33ARZ-RL7 guarantees RESET functionality?
The ADM13307-33ARZ-RL7 guarantees valid RESET output states down to VDD = 1.1 V, as confirmed in the General Description and Specifications sections. This ensures reliable reset assertion during initial power ramp-up and brownout conditions before full VDD stabilization.
Can the ADM13307-33ARZ-RL7 be used to monitor a 1.8 V supply?
No-the ADM13307-33ARZ-RL7 is configured for 4.55 V, 2.93 V, and adjustable 1.25 V reference inputs. To supervise a 1.8 V rail, use the ADM13307-18ARZ-RL7 variant, which has fixed thresholds at 2.93 V, 1.68 V, and 1.25 V. The -33 variant's SENSE2 threshold (2.93 V) is not suitable for direct 1.8 V monitoring.
What package type and RoHS status does the ADM13307-33ARZ-RL7 have?
The ADM13307-33ARZ-RL7 is supplied in an 8-lead narrow-body SOIC (SOIC_N, JEDEC MS-012-AA, package code R-8) and is RoHS compliant, as indicated by the "Z" suffix in the part number per the Ordering Guide. The "-RL7" suffix denotes tape-and-reel packaging with 1,000 units per reel.
