Analog Devices Inc./Maxim Integrated MAX16006ATG+T

Overview

MAX16006ATG+T 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. It provides eight open-drain outputs with internal 30µA pullups, a shared active-low RESET output, manual reset (MR), margin enable (MARGIN), watchdog timer (1.6s typ timeout), and capacitor-adjustable reset timeout (min 140ms). It is used in multivoltage server power sequencing and ASIC supervisory systems.

For engineers reviewing the MAX16006ATG+T datasheet, MAX16006ATG+T pinout, MAX16006ATG+T application, or MAX16006ATG+T equivalent, key selection considerations include its 8-channel voltage monitoring capability, guaranteed operation down to VCC = 1V, -40°C to +125°C industrial temperature range, watchdog startup delay (54s), and compatibility with 0.1µF VCC bypassing.

Technical Context

The MAX16006ATG+T implements independent voltage monitoring per channel with hysteresis (0.5% of threshold), fixed or adjustable thresholds selected via TOL pin, and propagation delay ≤20µs from input fall to output assertion. Its watchdog timer clears on any WDI edge and enters a 54s startup window before first timeout enforcement.

RESET asserts when any monitored voltage drops below its threshold or MR is pulled low; it remains asserted for the full timeout period after all voltages recover and MR is released. SRT pin supports either internal 140ms minimum timeout (SRT = VCC) or external capacitor adjustment (t_RP = 2.06 MΩ × C_SRT).

FAQ

What is the operating temperature range for the MAX16006ATG+T?

The MAX16006ATG+T is fully specified from -40°C to +125°C. This extended industrial temperature range ensures reliable operation in server chassis, telecom line cards, and industrial control cabinets where ambient temperatures exceed standard commercial limits. The device maintains parameter accuracy across this range, including threshold tolerance, reset timeout, and watchdog timing.

Does the MAX16006ATG+T require external pullup resistors on its outputs?

No, the MAX16006ATG+T does not require external pullup resistors. All open-drain outputs (OUT1–OUT8 and RESET) integrate internal 30µA pullups to VCC. This eliminates eight external resistors, reduces PCB area, and simplifies layout - especially critical in dense server and networking applications where board space is at a premium.

How is the reset timeout period configured on the MAX16006ATG+T?

The MAX16006ATG+T supports two reset timeout modes: fixed minimum (140ms) or capacitor-adjustable. To use the fixed mode, connect the SRT pin to VCC. For adjustable timing, connect a capacitor from SRT to GND; timeout = 2.06 MΩ × C_SRT. For example, a 1500pF capacitor yields ~3.09ms, while 100nF yields ~206ms - enabling precise system-level coordination.

Can the MAX16006ATG+T monitor a 0.9V supply rail?

Yes, the MAX16006ATG+T can monitor a 0.9V supply rail. When ordered as variant MAX16006F, it is factory-configured with fixed thresholds of 5.0V, 3.3V, 3.0V, 2.5V, 1.8V, 1.5V, 1.2V, and 0.9V - all with ±5% or ±10% tolerance selectable via the TOL pin. This makes it suitable for modern low-voltage ASICs and processors.

What happens to the outputs when the MARGIN pin is pulled low on the MAX16006ATG+T?

When the MARGIN pin is pulled low on the MAX16006ATG+T, all eight OUTx outputs and the RESET output are forced into a high-impedance (deasserted/high) state - regardless of actual input voltage conditions. This enables safe margin testing during production, allowing verification of downstream logic under controlled fault conditions without triggering unintended system resets.
