Product details
Overview
MAX16062DTG+ from Maxim Integrated is an octal-voltage microprocessor supervisor IC designed for multivoltage system monitoring in industrial and automotive electronics. It monitors eight independent supply rails (e.g., 3.3V, 2.5V, 1.8V, and adjustable down to 0.4V), provides eight open-drain voltage-monitor outputs with internal 30µA pullups, and asserts a shared active-low RESET output when any monitored voltage falls below its threshold or upon manual reset assertion. It operates across –40°C to +125°C and supports margin testing via MARGIN pin.
For engineers reviewing the MAX16062DTG+ datasheet, MAX16062DTG+ pinout, MAX16062DTG+ application, or MAX16062DTG+ equivalent, key selection considerations include its 1% threshold accuracy over temperature, capacitor-adjustable or fixed 140ms minimum reset timeout, integrated watchdog timer (1.6s typical timeout), tolerance-selectable thresholds (5%/10%), and 24-pin 4mm × 4mm thin QFN package with exposed pad.
Technical Context
The MAX16062DTG+ implements eight independent voltage comparators with hysteresis (0.5% of threshold), each feeding dedicated open-drain OUT_ outputs. Its RESET output is logically OR'd across all eight monitor channels and the manual reset (MR) input, with reset timeout determined either by internal 140ms minimum or externally via SRT pin capacitor (tRP = 2.06 × 10⁶ × CSRT).
It integrates a watchdog timer with 54s startup delay and 1.6s typical timeout, disabled by leaving WDI floating; a TOL pin selects 5% or 10% threshold tolerance; and a MARGIN pin enables simultaneous deassertion of all outputs during margin testing. All outputs remain functional down to VCC = 1V, and supply current is 65µA typical at VCC = 3.3V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | Eight independent inputs (IN1–IN8), supporting fixed (3.3V/2.5V/1.8V) and adjustable thresholds down to 0.4V |
| Threshold Accuracy | ±1% over –40°C to +125°C - ensures reliable brownout detection without calibration |
| Reset Timeout | Fixed 140ms minimum or capacitor-adjustable (e.g., 1500pF → 3.09ms) - enables precise power sequencing control |
| Watchdog Timeout | 1.6s typical (1.12–2.40s range) with 54s startup delay - prevents spurious resets during boot |
| Supply Voltage Range | VCC = 1.0V to 5.5V - guarantees RESET assertion integrity even during deep undervoltage |
| Output Type | Eight open-drain OUT_ pins + one open-drain RESET, each with internal 30µA pullup to VCC - eliminates external pullup resistors in most 3.3V/2.5V logic interfaces |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial control applications |
Pinout & Package
MAX16062DTG+ uses a 24-pin thin QFN package (4mm × 4mm, 0.5mm pitch) with exposed thermal pad (EP) internally connected to GND. The package supports high-density PCB layouts and efficient thermal dissipation in space-constrained systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN8 | Monitored voltage inputs | Eight independent analog inputs accepting fixed (3.3V/2.5V/1.8V) or adjustable (≥0.4V) thresholds; hysteresis = 0.5% VTH |
| OUT1–OUT8 | Independent voltage-monitor outputs | Open-drain outputs that go low when corresponding INx falls below threshold; 30µA internal pullup to VCC |
| RESET | Global reset output | Active-low open-drain output asserted if any INx < threshold or MR asserted; remains low for full reset timeout after recovery |
| MR | Manual reset input | Active-low input with 20kΩ internal pullup; pulse width ≥1µs required to trigger reset |
| SRT | Reset timeout programming | Connect capacitor to GND to set timeout (tRP = 2.06M × C); tie to VCC for fixed 140ms minimum |
| WDI | Watchdog timer input | Edge-sensitive input; watchdog disabled when left floating (400nA unconnected-state detector) |
| MARGIN | Margin test enable | Active-low input that forces all OUTx and RESET high regardless of input voltages - enables safe margin testing |
| TOL | Threshold tolerance select | Connect to GND for ±5% threshold tolerance, or to VCC for ±10% - adjusts comparator hysteresis |
| VCC | Power supply input | Unmonitored supply rail (1.0–5.5V); powers internal circuitry and serves as pullup reference for open-drain outputs |
| GND / EP | Ground reference / thermal pad | EP is electrically tied to GND; must be soldered to PCB ground plane for thermal management, not used as sole GND connection |

FAQ
What is the function of the TOL pin on the MAX16062DTG+?
The TOL pin on the MAX16062DTG+ selects the threshold tolerance for all monitored inputs: connecting TOL to GND sets ±5% tolerance, while connecting it to VCC sets ±10% tolerance. This adjusts the hysteresis width (0.5% VTH) and accommodates varying supply stability requirements across different system generations or operating conditions - a feature confirmed in the Electrical Characteristics table and Pin Description section of the MAX16062DTG+ datasheet.
Can the MAX16062DTG+ monitor voltages below 1.0V?
Yes, the MAX16062DTG+ supports adjustable input thresholds as low as 0.394V (TOL = GND) or 0.373V (TOL = VCC), enabling monitoring of sub-1.0V rails such as 0.85V GPU cores or 0.75V AI accelerator supplies using external resistor dividers. The device guarantees operation down to VCC = 1.0V, and all OUT_ outputs remain functional with 30µA internal pullups - verified in the Absolute Maximum Ratings and Electrical Characteristics sections.
How is the reset timeout configured on the MAX16062DTG+?
The reset timeout on the MAX16062DTG+ is configured via the SRT pin: tying SRT to VCC activates the internal 140ms minimum timeout, while connecting a capacitor from SRT to GND sets a custom timeout per tRP = 2.06 × 10⁶ × CSRT. For example, a 1500pF capacitor yields ~3.09ms. This relationship is specified in the Electrical Characteristics table and validated in Typical Operating Characteristics figure toc10 - ensuring predictable timing across temperature.
Does the MAX16062DTG+ require external pullup resistors for its outputs?
No, the MAX16062DTG+ does not require external pullup resistors for normal operation: all eight OUT_ outputs and the RESET output feature internal 30µA pullups to VCC, sufficient to drive standard CMOS inputs in 3.3V and 2.5V systems. External pullups are optional only when interfacing to logic with different supply voltages (up to 5.5V), as explicitly stated in the General Description and Pin Description sections.
What happens to the MAX16062DTG+ outputs during margin testing?
When the MARGIN pin on the MAX16062DTG+ is pulled low, all eight OUT_ outputs and the RESET output are forced into a high-impedance (deasserted) state regardless of input voltage conditions - enabling safe voltage margining without disrupting system operation. This behavior is documented in the Features list, Applications Information section, and Pin Description, with a specified 50µs delay (tMD) for logic locking/unlocking.
