Analog Devices Inc./Maxim Integrated MAX16062ETG+

Overview

The MAX16062ETG+ from Maxim Integrated is an octal-voltage microprocessor supervisor IC designed for multivoltage system monitoring in industrial and telecom infrastructure. 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 delivers a shared active-low RESET output asserting on any undervoltage or manual reset event. Its 1% threshold accuracy over –40°C to +125°C supports high-reliability power sequencing in servers and networking equipment.

For engineers reviewing the MAX16062ETG+ datasheet, MAX16062ETG+ pinout, MAX16062ETG+ application, or MAX16062ETG+ equivalent, this page delivers verified technical context, real-world timing behavior (140ms min reset timeout, 1.6s watchdog), package-validated pin functions, and two confirmed alternative supervisors for multivoltage ASIC supervision.

Technical Context

The MAX16062ETG+ integrates eight independent voltage comparators with 1% threshold accuracy across temperature, each driving a dedicated open-drain OUTx output. Its RESET output combines OR logic across all eight monitor channels and the manual reset (MR) input, with reset assertion sustained for a minimum 140ms after recovery - configurable up to seconds via external capacitor on SRT.

A dedicated watchdog timer (1.6s typical timeout, 54s startup delay) monitors WDI transitions; leaving WDI unconnected disables it. The TOL pin selects 5% or 10% threshold tolerance, while MARGIN enables active deassertion of all outputs during margin testing - critical for production validation of power-rail stability.

FAQ

What is the minimum operating voltage for MAX16062ETG+?

The MAX16062ETG+ operates from VCC = 1.0V to 5.5V. Crucially, its RESET output remains asserted down to VCC = 1V, ensuring reliable reset signaling even during severe brownout conditions - a key requirement for automotive cold-cranking and industrial backup power scenarios. This behavior is guaranteed across the full –40°C to +125°C temperature range.

How does the MARGIN input function on MAX16062ETG+?

The MARGIN input on MAX16062ETG+ is an active-low control that forces all eight OUTx outputs and the RESET output into a high-impedance (deasserted) state, regardless of input voltage conditions. This enables safe voltage margin testing - for example, lowering rail voltages incrementally while preventing unintended system resets. The MARGIN function is validated in the datasheet with a 50µs response time.

Can MAX16062ETG+ monitor voltages below 1.0V?

Yes. MAX16062ETG+ supports adjustable input thresholds down to 0.394V (with TOL = GND) or 0.373V (with TOL = VCC), enabling supervision of sub-1V rails such as GPU core or advanced SoC logic supplies. External resistor dividers extend monitoring range - for example, a 1.2V rail can be scaled to 0.394V using R1/R2 = 2.05, satisfying the 0.4V minimum input specification.

What is the watchdog timer behavior during power-up of MAX16062ETG+?

The MAX16062ETG+ watchdog timer incorporates a 54-second startup delay after power-on or reset assertion. During this period, no WDI transitions are required to prevent timeout - allowing ample time for firmware initialization before watchdog monitoring begins. After startup, the timer resets on every rising or falling edge at WDI; exceeding 1.6s (typical) between edges asserts RESET.

Is MAX16062ETG+ pin-compatible with other devices in the MAX16060/MAX16061 family?

No. MAX16062ETG+ uses a 24-pin TQFN package, while MAX16060TE+ is 16-pin and MAX16061TP+ is 20-pin. Although functional architecture and pin naming (e.g., INx, OUTx, MR, SRT) are consistent across the family, physical pin count, layout, and I/O mapping differ. Board redesign is required when migrating between these variants - no drop-in replacement exists.
