Analog Devices Inc./Maxim Integrated MAX16062DTG+T

Overview

The MAX16062DTG+T from Maxim Integrated is an octal-voltage microprocessor supervisor IC designed for multivoltage system monitoring in industrial and telecom equipment. It monitors eight independent supply rails (including 3.3V, 2.5V, 1.8V, and adjustable down to 0.373V), provides 1% threshold accuracy over –40°C to +125°C, features a 1.6s typical watchdog timeout, and delivers open-drain outputs with internal 30µA pullups - enabling reliable power-on reset and undervoltage detection in high-density server power systems.

For engineers reviewing the MAX16062DTG+T datasheet, MAX16062DTG+T pinout, MAX16062DTG+T application, or MAX16062DTG+T equivalent, key selection considerations include its 24-pin TQFN-EP (4mm × 4mm) package, factory-preset threshold configuration (MAX16062D: IN1=3.3V, IN2=2.5V, IN3=ADJ, IN4=1.8V, IN5–IN8=ADJ), capacitor-adjustable reset timeout (min 140ms), and guaranteed RESET assertion down to VCC = 1V.

Technical Context

This device implements eight independent voltage comparators with hysteresis (0.5% of threshold), a shared active-low open-drain RESET output that latches on any fault or MR assertion, and a dedicated watchdog timer with 54s startup delay and 1.12–2.40s timeout range. All monitored inputs support either fixed thresholds or resistor-divider-based adjustment using the same 0.373V/0.394V reference depending on TOL pin state.

The architecture integrates tolerance-select logic (5% or 10% threshold margin via TOL pin), margin-enable functionality (MARGIN pin deasserts all outputs during test), and SRT-controlled reset timeout scaling via external capacitor - all while maintaining <70µA supply current at 5V and operation down to VCC = 1.0V.

FAQ

What is the factory-preset threshold configuration for MAX16062DTG+T?

The MAX16062DTG+T corresponds to the MAX16062D variant per Table 1: IN1 = 3.3V, IN2 = 2.5V, IN3 = adjustable (ADJ), IN4 = 1.8V, and IN5–IN8 = adjustable. This mixed configuration supports both standard logic rails and custom low-voltage domains without external resistor networks on fixed inputs.

Does MAX16062DTG+T require external pullup resistors on its open-drain outputs?

No - MAX16062DTG+T integrates 30µA internal pullups on all OUT1–OUT8 and RESET pins, sufficient for interfacing with standard 3.3V or 5V CMOS logic. External pullups are optional only when driving loads referenced to voltages outside the VCC range (up to 5.5V).

How is the reset timeout period set on MAX16062DTG+T?

The reset timeout is set via the SRT pin: connecting SRT to VCC selects the internal minimum of 140ms; connecting an external capacitor (CSRT) from SRT to GND scales the timeout using tRP = 2.06 × 10⁶ × CSRT seconds - e.g., 1500pF yields ~3.09ms typical.

Can the watchdog timer in MAX16062DTG+T be disabled?

Yes - leaving the WDI pin unconnected disables the watchdog timer. The device uses a 400nA detection current to sense the unconnected state; avoid connecting WDI to any source/sink exceeding ±200nA to prevent unintended activation.

What is the operating temperature range guaranteed for MAX16062DTG+T?

MAX16062DTG+T is fully specified from –40°C to +125°C ambient temperature, with all electrical parameters (including 1% threshold accuracy and RESET assertion down to VCC = 1V) guaranteed across this range - meeting requirements for under-hood automotive and industrial base station deployments.
