Analog Devices Inc./Maxim Integrated MAX16006BTG+T

Overview

MAX16006BTG+T from Maxim Integrated is an octal-voltage microprocessor supervisor IC designed for multivoltage system monitoring in industrial and computing applications. It monitors 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), provides independent open-drain outputs per rail, features a 140ms minimum reset timeout (capacitor-adjustable), and operates across –40°C to +125°C.

For engineers reviewing the MAX16006BTG+T datasheet, MAX16006BTG+T pinout, MAX16006BTG+T application, or MAX16006BTG+T equivalent, key selection criteria include its 8-channel monitoring capability, TQFN-24 package with exposed pad, watchdog timer with 1.6s timeout, manual reset input with 200ns glitch rejection, and tolerance-selectable 5%/10% threshold accuracy.

Technical Context

The MAX16006BTG+T implements independent voltage monitoring per channel with fixed and adjustable thresholds, using internal comparators with 0.5% hysteresis. Its reset logic asserts a shared active-low RESET output when any monitored voltage falls below its threshold or MR is pulled low, holding assertion for the full timeout period after all voltages recover and MR is released.

It integrates a watchdog timer with 1.6s typical timeout and 54s startup delay, disabled by leaving WDI floating. All open-drain outputs include 30µA internal pullups, eliminating external resistors while supporting external drive up to 5.5V - enabling direct interfacing with diverse logic families without level-shifting.

Key Specifications

Pinout & Package

Manufacturer

Maxim Integrated, now part of Analog Devices, designs precision analog, mixed-signal, and power management ICs for industrial, computing, communications, and automotive markets.

The MAX16000–MAX16007 family was engineered specifically for robust, low-power supervision of complex multivoltage systems in harsh thermal environments - emphasizing configurability, integration, and guaranteed operation down to VCC = 1V.

FAQ

What is the function of the TOL pin on the MAX16006BTG+T?

The TOL pin on the MAX16006BTG+T selects threshold tolerance: connecting it to GND enables ±5% accuracy for fixed thresholds, while connecting it to VCC selects ±10%. This setting directly controls the hysteresis window of each voltage comparator, affecting noise immunity and re-trigger stability during marginal supply conditions. The MAX16006BTG+T's TOL pin does not affect adjustable-threshold channels.

Does the MAX16006BTG+T provide independent reset outputs per monitored rail?

No, the MAX16006BTG+T does not provide independent reset outputs per rail. It offers eight independent open-drain OUT1–OUT8 outputs that assert low individually when their corresponding IN1–IN8 voltage falls below threshold. However, it provides only one shared active-low RESET output that asserts whenever *any* monitored voltage fails or MR is pulled low. This dual-output architecture balances granular fault visibility with system-level reset coordination.

How is the reset timeout period set on the MAX16006BTG+T?

The reset timeout on MAX16006BTG+T is set via the SRT pin: connecting SRT to VCC selects the internal minimum timeout of 140ms, while connecting an external capacitor from SRT to GND adjusts the timeout using tRP (s) = 2.06 × 10⁶ × CSRT (F). For example, a 1500pF capacitor yields ~3.09ms. The MAX16006BTG+T's SRT input has a 600nA ramp current and 1.235V threshold, enabling precise, temperature-stable timing without external RC components.

Can the MAX16006BTG+T monitor a 5V supply rail?

Yes, the MAX16006BTG+T can monitor a 5V supply rail - but only in specific variant configurations. The MAX16006F variant (not MAX16006B) provides factory-programmed fixed thresholds including 5.0V, 3.3V, 3.0V, 2.5V, 1.8V, 1.5V, 1.2V, and 0.9V. The MAX16006BTG+T corresponds to the 'B' variant, which supports 3.3V, adjustable, adjustable, 1.8V, adjustable, adjustable, adjustable, and adjustable - so 5V monitoring requires either the F variant or use of the adjustable input mode with external resistor divider.

What is the purpose of the MARGIN pin on the MAX16006BTG+T?

The MARGIN pin on the MAX16006BTG+T is an active-low input that forces all eight OUTx outputs and the RESET output into a high (deasserted) state when pulled low - regardless of actual supply voltages. This enables safe margin testing during production, where supplies are intentionally varied while the system remains logically operational. The MAX16006BTG+T's MARGIN pin has a 20kΩ internal pullup and 50µs response delay, ensuring glitch-free deassertion during test transitions.
