Product details
Overview
MAX16061ATP+ from Maxim Integrated is a 1% accurate, hex-voltage microprocessor supervisor IC in a 20-pin thin QFN (4mm × 4mm) package, monitoring six independent supply rails (e.g., 3.3V, 2.5V, 1.8V, and adjustable down to 0.373V), featuring open-drain outputs with internal 30µA pullups, a 140ms minimum reset timeout, and a 1.6s typical watchdog timer - deployed in multivoltage server power sequencing and telecom system supervision.
For engineers reviewing the MAX16061ATP+ datasheet, MAX16061ATP+ pinout, MAX16061ATP+ application, or MAX16061ATP+ equivalent, this page delivers verified circuit role, threshold accuracy over temperature, watchdog startup delay, margin enable functionality, and factory-preset voltage configuration details required for high-reliability embedded power management design.
Technical Context
The MAX16061ATP+ implements six independent voltage comparators with 1% threshold accuracy across –40°C to +125°C, each driving an open-drain output with internal 30µA pullup; its RESET output asserts when any monitored rail falls below its threshold or MR is asserted, remaining active for ≥140ms after recovery. The watchdog timer (1.6s typ timeout, 54s startup delay) clears on WDI edge transitions and disables when WDI is left floating.
Threshold tolerance is selected via TOL pin (5% at GND, 10% at VCC); adjustable inputs accept thresholds as low as 0.373V (TOL = VCC); all OUT_ outputs and RESET are open-drain, supporting external pullup to voltages up to 5.5V while guaranteeing assertion down to VCC = 1V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | Six independent rails (IN1–IN6), including factory-preset 3.3V/2.5V/1.8V and adjustable thresholds |
| Threshold Accuracy | ±1% over –40°C to +125°C - enables precise brownout detection without calibration |
| Reset Timeout | Min 140ms fixed (SRT = VCC) or capacitor-adjustable - supports reliable power-rail stabilization timing |
| Watchdog Timeout | 1.12s to 2.40s (typ 1.6s), with 35s–72s startup delay - prevents spurious resets during boot |
| Supply Voltage Range | VCC = 1.0V to 5.5V - ensures operation during deep brownout and compatibility with 1.2V–5V systems |
| Output Type | Open-drain OUT1–OUT6 and RESET with internal 30µA pullup - eliminates six external resistors |
| Operating Temp | –40°C to +125°C - qualified for automotive under-hood and industrial control environments |
Pinout & Package
MAX16061ATP+ uses a 20-pin thin QFN package (4mm × 4mm, exposed pad), RoHS-compliant and lead-free (+ suffix), rated for –40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–3 (IN4–IN6) | Monitored input voltage 4–6 | Accept factory-preset or adjustable thresholds (down to 0.373V); require no external bias when unused |
| 4 (WDI) | Watchdog timer input | Edge-sensitive; floating disables watchdog; leakage <200nA prevents false triggering |
| 5 (GND) | Ground reference | Primary return path; EP internally connected to GND for thermal conduction |
| 6 (VCC) | Unmonitored supply input | Powers IC; outputs guaranteed active down to VCC = 1V |
| 7–9 (OUT4–OUT6) | Independent open-drain outputs | Assert low on undervoltage; 30µA internal pullup eliminates external resistors |
| 10 (MR) | Active-low manual reset input | Pulled up to VCC via 20kΩ; 1µs min pulse width; 200ns glitch rejection |
| 11 (SRT) | Reset timeout capacitor interface | Connect to GND for adjustable timeout; SRT = VCC selects 140ms min internal timeout |
| 12 (MARGIN) | Active-low margin enable input | Deasserts all outputs during test; 50µs logic lock/unlock delay |
| 13–15 (OUT3–OUT1) | Independent open-drain outputs | Correspond to IN3–IN1; same electrical specs as OUT4–OUT6 |
| 16 (RESET) | Global active-low reset output | Asserts if any INx fails or MR is pulled low; open-drain with 30µA pullup |
| 17–19 (IN1–IN3) | Monitored input voltage 1–3 | Support 3.3V/2.5V/1.8V presets or adjustable thresholds per Table 1 |
| 20 (TOL) | Tolerance select input | GND = ±5% threshold tolerance; VCC = ±10% - sets hysteresis and accuracy band |
Key Features
| Feature | Design Value |
|---|---|
| 1% threshold accuracy over temperature | Enables single-supervisor replacement of multiple discrete monitors in high-precision systems |
| Internal 30µA pullups on all outputs | Removes need for six external pullup resistors, reducing BOM count and PCB area |
| Capacitor-adjustable reset timeout | Allows precise tailoring of reset hold time (e.g., 200ms–2s) to match specific power-rail ramp profiles |
| Margin enable function | Permits safe deassertion of all outputs during functional margin testing without altering supply conditions |
| Watchdog with 54s startup delay | Prevents premature timeout during long-boot processors (e.g., FPGAs, SoCs) before software initialization |
| Adjustable thresholds down to 0.373V | Supports monitoring of ultra-low-voltage rails (e.g., 1.0V core, 0.8V I/O) using external resistor dividers |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G33DBVR | Single 3.3V supervisor; no multi-rail monitoring, no watchdog, no margin enable | Limited to single-rail systems; lacks hex-monitoring capability and adjustable thresholds | Select only when supervising one rail and requiring ultra-low quiescent current (1.5µA) |
| ADM1266ACPZ | 16-channel sequencer/supervisor with I²C interface, programmable thresholds, and EEPROM; 40-pin LFCSP | Requires firmware configuration and host MCU coordination; higher cost and layout complexity | Choose for systems needing dynamic threshold adjustment or event logging, not for fixed-function simplicity |
Compared with TPS3808G33DBVR and ADM1266ACPZ, the MAX16061ATP+ uniquely delivers six independent, ±1% accurate voltage monitors in a compact 20-pin QFN without software dependency - optimizing for deterministic, hardware-based multirail supervision in space-constrained industrial and telecom designs.

FAQ
What voltage rails does the MAX16061ATP+ monitor, and how are thresholds configured?
The MAX16061ATP+ monitors six independent voltage rails (IN1–IN6). Thresholds are factory-preset per variant (e.g., MAX16061A = 3.3V/2.5V/ADJ/1.8V/ADJ/ADJ) and include fixed 3.3V, 2.5V, 1.8V options plus adjustable inputs down to 0.373V. TOL pin selects ±5% (GND) or ±10% (VCC) tolerance. Configuration is set at manufacture - no runtime programming.
Does the MAX16061ATP+ require external pullup resistors on its outputs?
No. The MAX16061ATP+ integrates 30µA internal pullups on all OUT1–OUT6 and RESET outputs, eliminating the need for external pullup resistors in standard 3.3V/5V logic interfaces. External pullups to voltages up to 5.5V are supported but optional - internal pullups remain active unless overridden.
How is the reset timeout period set on the MAX16061ATP+?
The MAX16061ATP+ offers two reset timeout modes: fixed 140ms minimum (by connecting SRT pin to VCC), or capacitor-adjustable (by connecting SRT to GND via CSRT). Timeout = 2.06 × 10⁶ Ω × CSRT (F); e.g., 100nF yields ~206ms. This allows precise alignment with power-rail stabilization times across diverse system designs.
Can the watchdog timer on the MAX16061ATP+ be disabled, and how?
Yes. The MAX16061ATP+ watchdog timer is disabled by leaving the WDI pin unconnected. An internal 400nA detector senses the floating state - ensure no external source sinks or sources >200nA to avoid false triggering. When enabled, WDI requires edges every 1.12–2.40s (typ 1.6s) to prevent RESET assertion.
What is the operating temperature range and package type of the MAX16061ATP+?
The MAX16061ATP+ is specified for –40°C to +125°C operation and housed in a 20-pin thin QFN package (4mm × 4mm, exposed pad), with lead-free + suffix and tape-and-reel packaging (2.5k units per reel). The exposed pad must be soldered to the PCB ground plane for thermal performance but is not an electrical ground connection.
