Analog Devices Inc./Maxim Integrated MAX16060ATE+

Overview

The MAX16060ATE+ from Maxim Integrated is a 1% accurate quad-voltage microprocessor supervisor IC in a 16-pin 4mm × 4mm thin QFN package. It monitors four independent supply rails (e.g., 3.3V, 2.5V, 1.8V, and adjustable down to 0.4V), provides four open-drain voltage-monitor outputs with internal 30µA pullups, and delivers a shared active-low RESET output that asserts when any monitored voltage falls below its threshold or upon manual reset. It is used in multivoltage ASIC power sequencing and fault monitoring for industrial servers.

For engineers reviewing the MAX16060ATE+ datasheet, MAX16060ATE+ pinout, MAX16060ATE+ application, or MAX16060ATE+ equivalent, key selection criteria include its 1% threshold accuracy over –40°C to +125°C, capacitor-adjustable reset timeout (min 140ms), integrated watchdog timer (1.6s typical timeout), tolerance-selectable thresholds (5%/10%), and margin-enable functionality for production test.

Technical Context

The MAX16060ATE+ implements independent comparator-based voltage supervision per input channel, each with programmable hysteresis (0.5% of threshold) and factory-preset or resistor-adjustable thresholds. Its RESET output combines OR-logic across all four monitored inputs and the manual reset (MR) signal, with timing controlled by an internal current source charging the external SRT capacitor.

It integrates a watchdog timer with 54s startup delay and 1.6s typical timeout, disabled by leaving WDI floating; all open-drain outputs support external pullup to voltages up to 5.5V while maintaining guaranteed assertion down to VCC = 1V. The TOL pin selects 5% or 10% threshold tolerance, and MARGIN enables full output deassertion during margin testing.

Key Specifications

Pinout & Package

MAX16060ATE+ uses a 16-pin thin QFN package (4mm × 4mm, exposed pad), RoHS-compliant and lead-free (+ suffix). The exposed pad (EP) is internally connected to GND and must be soldered to the PCB ground plane for thermal management.

FAQ

What is the operating temperature range of the MAX16060ATE+?

The MAX16060ATE+ is fully specified from –40°C to +125°C. Its 1% threshold accuracy is guaranteed across this entire range, and it maintains functional RESET assertion down to VCC = 1V - making it suitable for under-hood automotive and industrial control applications where thermal stress is severe.

How does the reset timeout work on the MAX16060ATE+?

The MAX16060ATE+ offers two reset timeout modes: a fixed minimum of 140ms (by connecting SRT to VCC) or a user-adjustable timeout (by connecting a capacitor from SRT to GND). The timeout duration is calculated as tRP = 2.06 × 10⁶ Ω × CSRT, allowing precise tuning from ~200ms to several seconds based on capacitor value.

Can the MAX16060ATE+ monitor voltages below 1.0V?

Yes - the MAX16060ATE+ supports adjustable input thresholds down to 0.394V (TOL = GND) or 0.373V (TOL = VCC). Using external resistor dividers on IN1–IN4, it can accurately supervise sub-1V rails such as 0.85V GPU cores or 0.6V FPGA transceivers while maintaining 1% accuracy over temperature.

What happens to the outputs when the MARGIN pin is asserted on the MAX16060ATE+?

When the MARGIN pin is pulled low, all four OUTx outputs and the RESET output are immediately deasserted (driven high), overriding all voltage-monitoring conditions. This allows safe margin testing of power supplies without triggering false system resets - a feature not found in basic dual- or triple-supervisor ICs.

Is the watchdog timer on the MAX16060ATE+ enabled by default?

No - the watchdog timer on the MAX16060ATE+ is disabled by default and requires connection of the WDI pin to a toggling signal (e.g., processor GPIO or clock divider). Leaving WDI unconnected disables the watchdog entirely; the 54s startup delay prevents false timeout during boot, and the 1.6s typical timeout ensures robust runtime fault detection.
