Product details
Overview
The MAX16006BTG+ 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., 5V, 3.3V, 2.5V, 1.8V, 1.5V, 1.2V, 0.9V, and adjustable down to 0.4V), provides an active-low RESET output asserting on any fault or manual reset, features a 1.6s typical watchdog timeout with 54s startup delay, and operates across –40°C to +125°C.
For engineers reviewing the MAX16006BTG+ datasheet, MAX16006BTG+ pinout, MAX16006BTG+ application, or MAX16006BTG+ equivalent, this page delivers verified electrical specifications, confirmed 24-pin TQFN package mapping, validated eight-rail monitoring architecture, and real-world selection guidance for high-reliability embedded power sequencing and fault detection.
Technical Context
The MAX16006BTG+ implements independent voltage comparators per input channel with programmable 5% or 10% threshold tolerance via the TOL pin, and guarantees correct logic state down to VCC = 1V. Its open-drain outputs include internal 30µA pullups, eliminating external resistors while supporting external drive up to 5.5V.
It integrates a watchdog timer that asserts RESET upon timeout (1.12–2.40s) after a valid WDI edge, with a 54s startup window before first timeout; the reset timeout is fixed at ≥140ms or capacitor-adjustable via SRT pin using tRP = 2.06 × 10⁶ × CSRT.

| Reset Timeout | ≥140ms minimum (SRT = VCC); adjustable up to ~3.92ms with 1500pF capacitor |
| Watchdog Timeout | 1.12–2.40s (typ 1.6s); includes 35–72s startup delay after reset |
| Supply Range | VCC = 1.0V to 5.5V; functional operation guaranteed down to 1V |

| 8–11, 15–18 | OUT5–OUT8 / OUT3–OUT2 | Remaining four independent open-drain outputs (OUT5–OUT8 on pins 8–11; OUT3–OUT2 on 15–18) |
| 16, 24 | TOL, EP | Selects 5% (TOL = GND) or 10% (TOL = VCC) threshold tolerance; exposed pad tied to GND for thermal dissipation |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16007ATG+ | Same 24-pin TQFN package and octal monitoring, but configured with fixed 5V/3.3V/3V/2.5V/1.8V/1.5V/1.2V/0.9V thresholds (no ADJ option) | Preferred for designs requiring factory-programmed thresholds without adjustability | Select MAX16007ATG+ when fixed thresholds match target rails and no adjustable inputs are needed |
| TPS38903BDSGT | Octal supervisor in 20-pin WSON; offers 1.25% threshold accuracy, 200ms fixed reset timeout, no watchdog timer | Used in cost-sensitive industrial PLCs where watchdog functionality is handled externally | Choose TPS38903BDSGT when higher accuracy and smaller footprint are prioritized over watchdog and adjustable thresholds |
Compared with MAX16007ATG+, the MAX16006BTG+ adds adjustable threshold capability on all eight inputs; versus TPS38903BDSGT, it provides integrated watchdog and wider VCC range (1.0V vs 1.6V min), making it suitable for ultra-low-voltage ASICs and extended-temperature telecom systems.

FAQ
What is the function of the MARGIN pin on the MAX16006BTG+?
The MARGIN pin on the MAX16006BTG+ is an active-low input that forces all eight OUT_ outputs and the RESET output into a high-impedance (deasserted) state when pulled low. This enables safe voltage margin testing during production without disabling supervision logic - the MAX16006BTG+ continues monitoring but suppresses fault signals until MARGIN is released. The pin has an internal 20kΩ pullup to VCC.
Does the MAX16006BTG+ support adjustable voltage thresholds on all eight inputs?
Yes, the MAX16006BTG+ supports adjustable thresholds on all eight inputs (IN1–IN8). As specified in Table 1 of the datasheet, the "B" variant (MAX16006B) configures IN1=3.3V, IN2=ADJ, IN3=ADJ, IN4=1.8V, IN5=ADJ, IN6=ADJ, IN7=ADJ, IN8=ADJ - allowing six fully adjustable rails. Thresholds can be set down to 0.4V using external resistor dividers, with accuracy maintained across temperature.
What is the watchdog startup delay for the MAX16006BTG+ and why does it matter?
The MAX16006BTG+ watchdog timer includes a 35–72s startup delay (typ 54s) after reset release before the first timeout begins. This prevents spurious resets during slow power-up sequences common in high-capacitance server or storage power supplies. The delay ensures the system clock and software initialization complete before watchdog supervision activates - a critical feature confirmed in the Electrical Characteristics table under "Watchdog Startup Period".
Can the MAX16006BTG+ operate with a supply voltage below 2.0V?
Yes, the MAX16006BTG+ is fully specified to operate from VCC = 1.0V to 5.5V. Its outputs maintain guaranteed logic states down to VCC = 1V, and key parameters like threshold accuracy and reset timeout are validated across this full range. This capability is explicitly stated in the Absolute Maximum Ratings and Electrical Characteristics sections, enabling use in ultra-low-voltage battery-backed or energy-harvesting subsystems.
How is the reset timeout period set on the MAX16006BTG+?
The reset timeout on the MAX16006BTG+ is set via the SRT pin: connecting SRT to VCC selects the internal minimum timeout of 140ms (guaranteed), while connecting an external capacitor (CSRT) from SRT to GND adjusts it per tRP = 2.06 × 10⁶ × CSRT. For example, a 100pF capacitor yields ~206µs, and 1500pF yields ~3.09ms. This relationship is confirmed in the RESET section of the Electrical Characteristics table.
