Product details
Overview
ADM13307-5ARZRL7 from Analog Devices is a triple voltage supervisor IC designed to monitor three independent supply rails in microprocessor and DSP systems. It features one fixed 2.93 V threshold (SENSE1), two adjustable 0.6 V thresholds (SENSE2/SENSE3) with external resistor dividers, 140 ms minimum reset timeout, push-pull active-high and active-low RESET outputs, and operates from 2.0 V to 5.5 V over −40°C to +85°C. It is used in notebook computers for reliable power-on reset sequencing.
For engineers reviewing the ADM13307-5ARZRL7 datasheet, ADM13307-5ARZRL7 pinout, ADM13307-5ARZRL7 application, or ADM13307-5ARZRL7 equivalent, key selection criteria include its dual-adjustable 0.6 V sense inputs, guaranteed RESET assertion down to VDD ≥ 1.1 V, manual reset (MR) support, SOIC_N package compatibility, and low 40 μA supply current for portable system integration.
Technical Context
The ADM13307-5ARZRL7 implements independent undervoltage detection on three SENSE inputs using internal comparators with hysteresis (0 mV at 0.6 V, 30 mV at 2.93 V). Its reset logic includes a 140–280 ms timeout timer that masks propagation delay during power-up and fault recovery.
It supports manual reset assertion via MR pin with 100 ns minimum pulse width, and provides both push-pull RESET (active low) and RESET (active high) outputs capable of sourcing/sinking up to 5 mA, with VOH = VDD − 0.4 V at 3 mA and VOL = 0.4 V at 3 mA under 5.5 V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - supports wide-input industrial and computing power rails. |
| Fixed Sense Threshold | 2.93 V (SENSE1) - pretrimmed for accurate 3.3 V supply monitoring. |
| Adjustable Sense Thresholds | 0.6 V (SENSE2, SENSE3) - externally programmable via resistor dividers for custom rail monitoring. |
| Reset Timeout | 140 ms (min) - ensures stable processor initialization after power ramp. |
| Supply Current | 40 μA (max) - enables low-power operation in battery-backed or portable systems. |
| Operating Temperature | −40°C to +85°C - qualified for extended industrial environments. |
| RESET Output Type | Push-pull - eliminates need for external pull-up resistors on either RESET or RESET. |
Pinout & Package
ADM13307-5ARZRL7 is housed in an 8-lead narrow-body SOIC (SOIC_N, R-8) package per JEDEC MS-012-AA, with 1.27 mm lead pitch and 5.00 mm × 4.00 mm body dimensions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SENSE1 | Fixed-threshold voltage monitor input | Monitors 3.3 V rail at 2.93 V falling threshold; requires no external components. |
| SENSE2 | Adjustable-threshold voltage monitor input | Configured for 0.6 V threshold; uses external resistor divider to scale higher voltages. |
| SENSE3 | Adjustable-threshold voltage monitor input | Identical function to SENSE2; enables third independent rail monitoring. |
| GND | Analog and digital ground reference | Common return path for all internal comparators and output drivers. |
| VDD | Power supply input | Supplies internal circuitry; RESET asserts when VDD ≥ 1.1 V. |
| MR | Manual reset input | Active-low signal; initiates reset pulse with 100 ns minimum width. |
| RESET | Active-high push-pull reset output | Drives high during normal operation; pulls low during reset assertion. |
| RESET | Active-low push-pull reset output | Drives low during reset; returns high after timeout completes. |
Key Features
| Feature | Design Value |
|---|---|
| Dual 0.6 V adjustable sense inputs | Enables precise monitoring of low-voltage rails (e.g., core logic, I/O, or DDR supplies) using external resistor networks. |
| Guaranteed RESET at VDD ≥ 1.1 V | Ensures early reset assertion during brownout or slow power ramp, preventing processor lockup. |
| 140–280 ms reset timeout | Provides configurable delay before deassertion, accommodating diverse processor startup timing requirements. |
| Push-pull RESET and RESET outputs | Eliminates external pull resistors and reduces board space while supporting both active-high and active-low reset architectures. |
| −40°C to +85°C operation | Validated performance across full industrial temperature range without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6816EPA+ | Triple supervisor with fixed 2.63 V, 2.93 V, 4.63 V thresholds; no adjustable inputs; 200 ms timeout. | Lacks programmable sense capability; suited for fixed-rail systems only. | Select when all three rails match standard thresholds and external resistor networks are undesirable. |
| TPS3808G33DBVR | Single-channel supervisor with 3.3 V fixed threshold, 200 ms timeout, and 1.8 μA quiescent current. | Requires three separate devices to replicate triple monitoring; lower power but higher BOM count. | Select when ultra-low power dominates design priority and board area allows discrete implementation. |

FAQ
What is the exact threshold voltage for SENSE1 on the ADM13307-5ARZRL7?
The ADM13307-5ARZRL7 has a fixed SENSE1 threshold of 2.93 V (typical), with a specified range of 2.90 V to 2.98 V across −40°C to +85°C. This value is factory-trimmed and does not require external components, making it suitable for direct monitoring of 3.3 V supply rails without resistor dividers.
How do the adjustable SENSE2 and SENSE3 inputs work on the ADM13307-5ARZRL7?
The ADM13307-5ARZRL7 uses internal 0.6 V reference comparators on SENSE2 and SENSE3. To monitor higher voltages (e.g., 5 V or 12 V), an external resistor divider scales the input so that the voltage at the pin equals 0.6 V when the monitored rail reaches the desired trip point. The device datasheet provides the exact divider equation and layout guidance.
Does the ADM13307-5ARZRL7 provide reset assertion during brownout conditions?
Yes. The ADM13307-5ARZRL7 asserts RESET/RESET whenever any monitored SENSE input falls below its falling threshold (VIT−), including during brownout. For SENSE1, this is 2.90–2.98 V; for SENSE2/SENSE3, it is 0.595–0.605 V. The device also guarantees RESET assertion as soon as VDD reaches 1.1 V, ensuring early fault detection.
What is the reset timeout behavior of the ADM13307-5ARZRL7 after power-up?
After VDD exceeds 1.1 V, the ADM13307-5ARZRL7 begins monitoring SENSE inputs. Once all three rise above their respective thresholds, it holds RESET low for a minimum of 140 ms (typical 200 ms, max 280 ms) before releasing. This timeout is generated internally and is independent of external capacitance or resistor values.
Can the ADM13307-5ARZRL7 be used with a 1.8 V supply rail?
No - the ADM13307-5ARZRL7 is not rated for direct 1.8 V rail monitoring because its SENSE2 and SENSE3 inputs are configured for 0.6 V thresholds, and its SENSE1 is fixed at 2.93 V. To supervise a 1.8 V rail, use a resistor divider to scale it down to 0.6 V at SENSE2 or SENSE3. The device itself operates from 2.0 V to 5.5 V on VDD.
