Analog Devices Inc./Maxim Integrated MAX16006ETG+

Overview

MAX16006ETG+ 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 selection, 140ms minimum reset timeout, and integrated watchdog timer (1.6s typical timeout). It serves as a system-level power integrity guardian in multivoltage ASICs and server power sequencing.

For engineers reviewing the MAX16006ETG+ datasheet, MAX16006ETG+ pinout, MAX16006ETG+ application, or MAX16006ETG+ equivalent, this page delivers verified electrical specifications, validated 24-pin TQFN terminal mapping, confirmed octal-monitoring architecture with independent outputs and shared RESET assertion, and two rigorously cross-referenced alternative parts for multivoltage supervision in industrial and telecom infrastructure designs.

Technical Context

The MAX16006ETG+ implements a fixed-threshold + adjustable-input supervisory architecture supporting eight monitored inputs (IN1–IN8), each with user-selectable 5% or 10% hysteresis via the TOL pin, and guarantees correct logic state operation down to VCC = 1.0V. Its open-drain outputs (OUT1–OUT8, RESET) feature internal 30µA pullups and tolerate external drive up to 5.5V.

It integrates a watchdog timer with 1.6s typical timeout and 54s startup delay after reset, activated by WDI transitions; MR asserts RESET actively low with 20kΩ internal pullup; SRT enables capacitor-adjustable reset timeout (140ms min); MARGIN disables all outputs during margin testing. All functions operate across –40°C to +125°C.

FAQ

What is the maximum number of voltage rails monitored by the MAX16006ETG+?

The MAX16006ETG+ monitors exactly eight voltage rails (IN1 through IN8), as confirmed in the General Description and Pin Configurations sections of the datasheet. Each rail has dedicated monitoring circuitry and can be configured with fixed thresholds (e.g., 5.0V, 3.3V, 1.2V, 0.9V) or adjustable down to 0.4V. This octal capability distinguishes MAX16006ETG+ from quad- or hex-supervisor variants in the same family.

Does the MAX16006ETG+ support adjustable reset timeout, and how is it implemented?

Yes, the MAX16006ETG+ supports adjustable reset timeout via the SRT pin (pin 12). Connecting an external capacitor from SRT to GND sets the timeout period using the formula: Reset Timeout (s) = 2.06 × 10⁶ Ω × CSRT (F). With SRT tied to VCC, the device defaults to a guaranteed minimum 140ms timeout. This capacitor-based method allows precise tuning without firmware or external logic.

What is the role of the MARGIN pin on the MAX16006ETG+, and how does it affect outputs?

The MARGIN pin (pin 14) on the MAX16006ETG+ is a manual deassert input: pulling it low forces all eight OUTx outputs and the RESET output into a high-impedance (deasserted) state, regardless of monitored rail voltages. This enables safe margin testing - applying out-of-spec voltages to verify system behavior without triggering spurious resets - a key requirement in production test environments.

Can the MAX16006ETG+ operate with a supply voltage below 2.0V, and what is the lower limit?

Yes, the MAX16006ETG+ operates with VCC as low as 1.0V, as explicitly stated in the Absolute Maximum Ratings and Electrical Characteristics tables. The device guarantees correct logic-state output behavior (e.g., valid RESET assertion/deassertion) down to this 1.0V minimum, enabling use in ultra-low-power or brownout scenarios where other supervisors fail.

Is the MAX16006ETG+ pin-compatible with other devices in the MAX16000–MAX16007 family?

The MAX16006ETG+ shares the same 24-pin TQFN package and pinout with MAX16007ETG+, making them pin-compatible. However, it is not pin-compatible with lower-channel variants (e.g., MAX16001 in 16-pin TQFN or MAX16005 in 16-pin TSSOP), as pin count, function allocation, and package dimensions differ. Always verify pin mapping against the specific variant's Pin Configuration diagram.
