Analog Devices Inc./Maxim Integrated MAX16060DTE+T

Overview

The MAX16060DTE+T from Maxim Integrated is a 1% accurate quad-voltage microprocessor supervisor in a 16-pin 4mm × 4mm thin QFN package, monitoring four independent supply rails (3.3V, 2.5V, adjustable down to 0.4V, and 1.8V) with open-drain outputs, internal 30µA pullups, and a 140ms minimum reset timeout - deployed in multivoltage ASICs and server power sequencing.

For engineers reviewing the MAX16060DTE+T datasheet, MAX16060DTE+T pinout, MAX16060DTE+T application, or MAX16060DTE+T equivalent, this device delivers precise voltage supervision for complex embedded systems requiring guaranteed reset assertion down to VCC = 1V, watchdog timer functionality (1.6s typ), and margin testing support via MARGIN input.

Technical Context

The MAX16060DTE+T implements independent comparator-based voltage monitoring per input channel, with threshold accuracy maintained at ±1% over –40°C to +125°C. Its RESET output is asserted when any monitored voltage falls below its threshold or MR is pulled low, and remains asserted for a capacitor-adjustable or fixed 140ms timeout after all voltages recover and MR deasserts.

It integrates a watchdog timer with 1.6s typical timeout and 54s startup delay, disabled by leaving WDI floating; all OUT_ outputs are open-drain with internal 30µA pullups to VCC and tolerate external drive up to 5.5V. Threshold tolerance (5% or 10%) is selected via TOL pin, and margin testing is enabled by pulling MARGIN low to deassert all outputs.

Key Specifications

Pinout & Package

MAX16060DTE+T uses a 16-pin 4mm × 4mm thin QFN package with exposed pad (EP), rated for operation from –40°C to +125°C. The EP is internally connected to GND and must be soldered to the PCB ground plane for thermal management.

FAQ

What voltage rails does the MAX16060DTE+T monitor?

The MAX16060DTE+T monitors four independent voltage rails: IN1 = 3.3V, IN2 = 2.5V, IN3 = adjustable (0.394V typical with TOL = GND), and IN4 = 1.8V. This configuration matches the MAX16060D variant per Table 1 and supports supervision of core, I/O, and auxiliary supplies in complex ASIC or processor systems.

Does the MAX16060DTE+T include a watchdog timer?

Yes, the MAX16060DTE+T includes an integrated watchdog timer with a typical timeout period of 1.6s (1.12s to 2.40s range) and a 54s startup delay after reset. The watchdog can be disabled by leaving the WDI pin unconnected, and its operation is validated in the device's electrical characteristics table and functional diagram.

How is the reset timeout configured on the MAX16060DTE+T?

The MAX16060DTE+T offers dual reset timeout modes: a fixed minimum of 140ms (achieved by connecting SRT to VCC) or a capacitor-adjustable timeout calculated as tRP = 2.06 × 10⁶ Ω × CSRT (e.g., 1500pF yields ~3.09ms). This flexibility supports diverse power-rail ramp profiles without external timing components.

What is the purpose of the MARGIN pin on the MAX16060DTE+T?

The MARGIN pin on the MAX16060DTE+T is an active-low input that, when pulled low, forces all OUT1–OUT4 and RESET outputs into a high (deasserted) state regardless of input voltage conditions. This enables safe voltage margin testing during production validation without triggering unintended system resets.

Can the MAX16060DTE+T operate down to 1V supply voltage?

Yes, the MAX16060DTE+T is guaranteed to maintain asserted RESET output down to VCC = 1V, as explicitly stated in Note 2 of the Electrical Characteristics table. This ensures reliable brownout detection and reset hold during severe supply droop in automotive and industrial applications.
