Product details
Overview
The MAX16000ATC+T from Maxim Integrated is a low-voltage, quad-voltage microprocessor supervisor IC in a 12-pin TQFN (4mm × 4mm) package. It monitors four independent supply rails (e.g., 3.3V, 2.5V, adjustable, and 1.8V), provides independent open-drain outputs per channel, features a fixed 140ms minimum reset timeout, internal 30µA pullups, and operates across –40°C to +125°C - used for reliable power sequencing and fault detection in multivoltage server and storage systems.
For engineers reviewing the MAX16000ATC+T datasheet, MAX16000ATC+T pinout, MAX16000ATC+T application, or MAX16000ATC+T equivalent, this page delivers verified electrical specs, confirmed pin functions, exact package mapping (T1244+4, outline 21-0139), real-world use cases in storage equipment and networking gear, and two validated alternative parts with documented functional and application differences.
Technical Context
The MAX16000ATC+T implements independent voltage monitoring with fixed thresholds (3.3V, 2.5V, 1.8V) and one adjustable input (down to 0.4V), each with 0.5% hysteresis. Its reset logic asserts RESET low when any monitored voltage falls below its threshold or MR is pulled low, holding assertion for ≥140ms after recovery.
All outputs are open-drain with integrated 30µA pullups to VCC, eliminating external resistors; inputs tolerate voltages up to 6V, and logic remains valid down to VCC = 1V - enabling robust operation in noisy, low-voltage embedded environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | Four independent rails: 3.3V, 2.5V, adjustable (0.4V min), and 1.8V - supports mixed-supply ASIC/FPGA power domains. |
| Reset Timeout | ≥140ms minimum (internally fixed); no external capacitor required - simplifies BOM and layout for deterministic reset timing. |
| Supply Voltage Range | VCC = 1.0V to 5.5V - ensures correct logic state even during brownout conditions down to 1V. |
| Input Threshold Accuracy | ±2.5% over temperature (e.g., 3.3V threshold = 3.053V typ at TOL = GND) - enables precise margining of critical supplies. |
| Operating Temperature | –40°C to +125°C - qualified for industrial and automotive under-hood applications requiring extended thermal range. |
| Quiescent Current | 45–65µA at VCC = 3.3V - minimizes standby power in always-on systems like network switches. |
| Output Type | Open-drain with 30µA internal pullup - eliminates need for external pullup resistors while supporting 5.5V-tolerant driving. |
Pinout & Package
Package: 12-pin TQFN, 4mm × 4mm, exposed pad (EP), RoHS-compliant (package code T1244+4, outline 21-0139). Thermal pad must be soldered to PCB ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 10, 11 | IN1–IN4 | Independent monitored voltage inputs - each triggers dedicated output on undervoltage; IN1 = 3.3V, IN2 = 2.5V, IN3 = adjustable, IN4 = 1.8V (per MAX16000A variant). |
| 5, 6, 8, 9 | OUT1–OUT4 | Open-drain status outputs - go low when corresponding INx falls below threshold; internal 30µA pullup avoids external components. |
| 3 | GND | Ground reference and thermal path via exposed pad - must connect EP to PCB ground plane for thermal reliability. |
| 4 | VCC | Unmonitored bias supply - requires 0.1µF bypass capacitor to GND; powers internal circuitry and pullups. |
| 7 | MARGIN | Active-low manual deassert - pulls all OUTx high regardless of input states, enabling controlled system margin testing. |
| 12 | TOL | Threshold tolerance select - tied to GND for ±5%, to VCC for ±10%; sets hysteresis and accuracy window per input. |
Key Features
| Feature | Design Value |
|---|---|
| Independent per-rail monitoring | Four dedicated outputs enable granular fault isolation - e.g., detect 3.3V rail collapse without masking 1.8V issues. |
| Adjustable threshold input | IN3 supports 0.366V–0.400V (TOL-dependent) - allows custom monitoring of nonstandard supplies like 0.85V core rails. |
| No external pullup resistors | 30µA internal pullups on all outputs - reduces component count, PCB area, and assembly cost in space-constrained modules. |
| Fixed 140ms reset timeout | Guaranteed minimum delay without capacitor - ensures sufficient hold time for slow-ramping supplies (e.g., DDR memory rails). |
| 1V minimum VCC operation | Correct logic state maintained down to VCC = 1V - prevents spurious resets during deep brownout recovery. |
Applications
| Storage Equipment | Servers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16001ATC+T | Includes watchdog timer (1.6s timeout) and shared RESET output; same pinout and monitoring capability. | Required where system-level watchdog supervision is needed alongside voltage monitoring - e.g., unattended telecom base stations. | Select MAX16001ATC+T if watchdog functionality is mandatory; otherwise MAX16000ATC+T reduces complexity and cost. |
| TPS3808G33DBVR | Single 3.3V supervisor with 200ms fixed timeout; no multi-rail or adjustable threshold capability. | Only suitable for single-rail monitoring; lacks independent outputs and quad-channel flexibility. | Choose only for simple 3.3V-only systems - not a functional substitute for quad-rail supervision in multivoltage designs. |
Compared with MAX16001ATC+T, the MAX16000ATC+T omits the watchdog but retains identical quad-monitoring precision and pin compatibility - ideal for cost-sensitive, watchdog-free applications. Versus TPS3808G33DBVR, it delivers four independent rails and adjustable thresholds, making it irreplaceable in complex ASIC/FPGA power domains.

FAQ
What is the exact package type and footprint for MAX16000ATC+T?
The MAX16000ATC+T uses a 12-pin TQFN package measuring 4mm × 4mm with an exposed thermal pad (EP). Its official package code is T1244+4, outline number 21-0139, and land pattern number 90-0068 - all documented in Maxim's package drawings and compatible with standard reflow profiles including peak soldering at +260°C.
Does MAX16000ATC+T support adjustable voltage thresholds, and how is it configured?
Yes, the MAX16000ATC+T supports one adjustable threshold input (IN3), configurable from 0.366V to 0.400V depending on TOL pin state. When TOL = GND, threshold is 0.394V (±2.5%); when TOL = VCC, it is 0.372V (±5%). This enables precise monitoring of nonstandard rails like 0.85V or 0.9V cores without external resistor dividers.
How does the reset timeout work on MAX16000ATC+T, and is an external capacitor required?
The MAX16000ATC+T has a fixed minimum reset timeout of 140ms - achieved by connecting the SRT pin to VCC. No external capacitor is required for this default timing. For longer timeouts, a capacitor can be added from SRT to GND using the formula tRP = 2.06 × 10⁶ × CSRT (seconds), but the base configuration needs zero external components.
What is the function of the MARGIN pin on MAX16000ATC+T, and how is it used in practice?
The MARGIN pin on MAX16000ATC+T is an active-low manual deassert input. Pulling MARGIN low forces all four OUTx outputs high - overriding undervoltage conditions - enabling safe voltage margin testing during system validation. It is commonly driven by test fixtures or FPGA GPIOs to simulate "all-rails-good" states without altering actual supply levels.
Is MAX16000ATC+T compatible with 5V-tolerant I/O systems despite its 5.5V absolute max rating?
Yes, MAX16000ATC+T supports 5.5V absolute maximum voltage on all open-drain outputs (OUT1–OUT4, RESET) and inputs (MR, MARGIN, TOL, SRT), allowing direct interface with 5V logic families. However, VCC must remain within 1.0V–5.5V, and internal circuitry operates from VCC - so 5V-tolerant signaling is supported, but VCC itself may be lower (e.g., 3.3V) for reduced power.
