Analog Devices Inc./Maxim Integrated MAX16006ATG+

Overview

The MAX16006ATG+ from Maxim Integrated is an octal-voltage microprocessor supervisor IC in a 24-pin TQFN (4mm × 4mm) package, monitoring eight independent supply rails (e.g., 5V, 3.3V, 2.5V, 1.8V, 1.5V, 1.2V, 0.9V, and adjustable down to 0.4V) with ±5% or ±10% threshold tolerance selectable via the TOL pin. It features an active-low RESET output asserting when any monitored voltage falls below its threshold or MR is pulled low, with a minimum 140ms reset timeout (internally fixed or capacitor-adjustable), and includes watchdog timer functionality (1.6s typical timeout, 54s startup delay).

For engineers reviewing the MAX16006ATG+ datasheet, MAX16006ATG+ pinout, MAX16006ATG+ application, or MAX16006ATG+ equivalent, this device supports multivoltage system supervision in high-reliability industrial and telecom infrastructure where precise rail sequencing, margin testing, and fault detection across eight supplies are required.

Technical Context

The MAX16006ATG+ implements independent open-drain outputs for all eight monitored inputs (IN1–IN8), each with internal 30µA pullups eliminating external resistors. Its RESET output aggregates fault conditions across all rails and manual reset (MR), remaining asserted for the full timeout after recovery. The watchdog timer monitors WDI transitions and asserts RESET on timeout, with a 54s startup window before first evaluation.

Threshold selection is controlled by the TOL pin (GND = ±5%, VCC = ±10%), and the MARGIN pin enables simultaneous deassertion of all outputs during system margining. The SRT pin supports either internal 140ms timeout (SRT tied to VCC) or external capacitor-based adjustment (t_RP = 2.06 MΩ × C_SRT).

Key Specifications

Pinout & Package

MAX16006ATG+ uses a 24-pin TQFN package (4mm × 4mm, outline 21-0139, land pattern 90-0022) with exposed thermal pad (EP) internally connected to GND. Pin functions are validated per Maxim's official pin configuration diagram for MAX16006 (page 13–14 of datasheet Rev 9).

FAQ

What is the function of the TOL pin on the MAX16006ATG+?

The TOL pin on the MAX16006ATG+ selects threshold tolerance: connecting TOL to GND configures ±5% accuracy for all fixed thresholds (e.g., 3.3V, 2.5V), while connecting it to VCC selects ±10%. This setting applies uniformly across all eight monitored inputs and is validated over the full -40°C to +125°C operating range.

Does the MAX16006ATG+ support adjustable reset timeout, and how is it configured?

Yes, the MAX16006ATG+ supports adjustable reset timeout via the SRT pin. Connecting SRT to VCC enables the internal 140ms minimum timeout. For longer durations, connect an external capacitor from SRT to GND; timeout = 2.06 MΩ × C_SRT. For example, a 100nF capacitor yields ~206ms, validated per datasheet Figure 10.

How many independent voltage monitoring channels does the MAX16006ATG+ provide?

The MAX16006ATG+ provides eight independent voltage monitoring channels (IN1 through IN8), each with configurable thresholds (fixed or adjustable), individual open-drain outputs (OUT1–OUT8), and contribution to the shared active-low RESET output. This is confirmed in the General Description and Pin Configuration diagrams for MAX16006 on pages 1 and 13–14.

What is the purpose of the MARGIN pin on the MAX16006ATG+?

The MARGIN pin on the MAX16006ATG+ is an active-low input that forces all eight outputs (OUT1–OUT8) and the RESET output into a high (deasserted) state, regardless of input voltage conditions. This enables safe margin testing of power supplies without triggering false resets, and is electrically verified with 12–28kΩ internal pullup to VCC.

Is the MAX16006ATG+ watchdog timer compatible with firmware-driven health checks?

Yes, the MAX16006ATG+ watchdog timer supports firmware health checks via the WDI pin: a rising or falling edge clears the timer, and absence of transitions beyond 1.12–2.40s (typ 1.6s) asserts RESET. It includes a 54s startup delay after power-up or reset, allowing time for firmware initialization before monitoring begins.
