Product details
Overview
The MAX16060DTE+ from Maxim Integrated is a 1% accurate quad-voltage microprocessor supervisor IC in a 16-pin 4mm × 4mm thin QFN package, monitoring four independent supply rails (e.g., 3.3V, 2.5V, adjustable down to 0.4V, and 1.8V) with open-drain outputs, internal 30µA pullups, and a watchdog timer with 1.6s typical timeout. It serves as a system-level power integrity guardian in multivoltage ASIC and server power domains.
For engineers reviewing the MAX16060DTE+ datasheet, MAX16060DTE+ pinout, MAX16060DTE+ application, or MAX16060DTE+ equivalent, key selection criteria include its quad-supply monitoring capability, factory-preset threshold configuration (MAX16060D), 140ms minimum reset timeout, -40°C to +125°C operation, and integrated margin enable/manual reset functions.
Technical Context
The MAX16060DTE+ implements independent voltage comparators per input (IN1–IN4), each with 1% accuracy over temperature and user-selectable 5%/10% threshold tolerance via the TOL pin. Its RESET output asserts when any monitored rail falls below its threshold or MR is pulled low, remaining asserted for a capacitor-adjustable or fixed 140ms timeout after all rails recover and MR deasserts.
It integrates a watchdog timer with 54s startup delay and 1.6s typical timeout, disabled by leaving WDI floating; all eight outputs (four OUT_, RESET, MR, MARGIN, SRT, TOL) are logic-compatible across 1.0V–5.5V VCC, with guaranteed assertion down to VCC = 1V and open-drain outputs tolerant of external pullup voltages up to 5.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | Four independent rails (IN1–IN4), configured as 3.3V/2.5V/ADJ/1.8V per MAX16060D variant |
| Threshold Accuracy | ±1% over -40°C to +125°C - enables precise brownout detection without calibration |
| Reset Timeout | Fixed 140ms minimum or capacitor-adjustable (e.g., 1500pF → 3.09ms) - supports flexible system boot sequencing |
| Watchdog Timeout | 1.6s typical (1.12–2.40s range) with 54s startup delay - prevents premature timeout during processor initialization |
| Supply Range | VCC = 1.0V to 5.5V, with outputs guaranteed active down to VCC = 1V - ensures supervision during deep brownout |
| Output Type | Open-drain with internal 30µA pullup to VCC - eliminates external resistors for 3.3V/2.5V logic interfaces |
| Operating Temp | -40°C to +125°C - qualified for automotive under-hood and industrial embedded environments |
Pinout & Package
Package: 16-pin thin QFN (4mm × 4mm, exposed pad), RoHS-compliant and lead-free (+ suffix).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 14, 15 | IN3, IN4, IN1, IN2 | Four independent voltage monitor inputs - thresholds preset per MAX16060D (3.3V/2.5V/ADJ/1.8V) |
| 3 | WDI | Watchdog timer input - floating disables timer; edges reset timeout; 400nA unconnected-state detection |
| 4 | GND | Ground reference - EP internally connected to GND for thermal management |
| 5 | VCC | Unmonitored power supply input - powers internal circuitry and provides pullup reference |
| 6–7, 11–12 | OUT3, OUT4, OUT2, OUT1 | Open-drain status outputs - go low when respective IN_ falls below threshold; 30µA internal pullup |
| 8 | MR | Active-low manual reset - 20kΩ internal pullup; 1µs minimum pulse width; 200ns glitch rejection |
| 9 | SRT | Reset timeout set input - connect capacitor to GND for adjustable timeout; tie to VCC for 140ms min |
| 10 | MARGIN | Active-low margin enable - forces all OUT_ and RESET high during test, overriding voltage conditions |
| 13 | RESET | Active-low system reset output - asserts if any IN_ fails or MR is pulled low; same 30µA pullup |
| 16 | TOL | Tolerance select - GND = 5% threshold tolerance, VCC = 10% tolerance |
Key Features
| Feature | Design Value |
|---|---|
| Factory-preset thresholds | MAX16060D variant configures IN1–IN4 as 3.3V/2.5V/adjustable/1.8V - eliminates external resistor networks |
| Adjustable low-voltage monitoring | IN_ thresholds down to 0.394V (TOL = GND) - enables supervision of sub-1V core rails via resistive divider |
| Integrated margin enable | MARGIN pin deasserts all outputs during production testing - simplifies voltage margining without firmware changes |
| No external pullups required | 30µA internal pullups on all open-drain outputs - reduces BOM count and PCB area in space-constrained designs |
| Wide VCC operating range | Functional from 1.0V to 5.5V - supports supervision across legacy 5V, modern 3.3V/2.5V, and ultra-low-voltage domains |
Applications
| Server Power Sequencing | Automotive ADAS ECU |

FAQ
What voltage thresholds are factory-configured for MAX16060DTE+?
The MAX16060DTE+ is the MAX16060D variant, configured with factory-preset thresholds of 3.3V on IN1, 2.5V on IN2, adjustable (0.394V nominal, TOL = GND) on IN3, and 1.8V on IN4. These values are laser-trimmed for ±1% accuracy across -40°C to +125°C and do not require external resistor networks.
How does the MARGIN pin function on MAX16060DTE+?
The MARGIN pin on MAX16060DTE+ is an active-low input that forces all OUT_ outputs and the RESET output into a high (deasserted) state regardless of monitored voltage conditions. This enables safe voltage margin testing during production without triggering false resets or diagnostic alarms.
Can MAX16060DTE+ monitor voltages below 1.0V?
Yes - the MAX16060DTE+ supports adjustable thresholds down to 0.394V (with TOL = GND) on IN3 and IN4. By adding an external resistive divider, it can accurately supervise sub-1V core rails (e.g., 0.8V or 0.9V) while maintaining 1% accuracy over temperature.
What is the minimum VCC required for MAX16060DTE+ to assert RESET reliably?
The MAX16060DTE+ guarantees RESET assertion down to VCC = 1.0V, as specified in the Absolute Maximum Ratings and Electrical Characteristics tables. This ensures fail-safe supervision even during severe brownout conditions where main supply collapses near 1V.
Is the watchdog timer on MAX16060DTE+ enabled by default?
No - the watchdog timer on MAX16060DTE+ is disabled by default and requires connection of the WDI pin to a toggling signal. Leaving WDI unconnected activates an internal 400nA detector that holds the timer inactive, preventing unintended resets during power-up or idle states.
