Product details
Overview
The MAX16001BTE+T from Maxim Integrated is a quad-voltage microprocessor supervisor IC in a 16-pin TQFN (4mm × 4mm) package, monitoring four independent supply rails (3.3V, adjustable, adjustable, and 1.8V) with ±5% or ±10% threshold tolerance selection, 140ms minimum reset timeout, and integrated watchdog timer with 1.6s typical timeout - used for reliable power-up sequencing and fault detection in multivoltage server and storage systems.
For engineers reviewing the MAX16001BTE+T datasheet, MAX16001BTE+T pinout, MAX16001BTE+T application, or MAX16001BTE+T equivalent, key selection considerations include its fixed/adjustable voltage threshold configuration, open-drain outputs with internal 30µA pullups, manual reset and margin enable inputs, watchdog startup delay (54s), and guaranteed operation down to VCC = 1V.
Technical Context
The MAX16001BTE+T implements a dual-mode supervision architecture: independent open-drain outputs per monitored rail (OUT1–OUT4) plus a shared active-low RESET output that asserts when any input falls below threshold or MR is pulled low. Its watchdog timer clears on WDI edge transitions and enters a 54s startup window before first timeout evaluation.
Threshold selection is controlled via the TOL pin (GND = ±5%, VCC = ±10%), while reset timeout is set either internally (140ms min, SRT = VCC) or externally via capacitor on SRT (tRP = 2.06 MΩ × CSRT). All outputs remain valid down to VCC = 1V, supporting low-voltage system operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | Four rails: IN1 = 3.3V, IN2 = adjustable (0.366–0.400V), IN3 = adjustable, IN4 = 1.8V - enables flexible multirail ASIC/FPGA power monitoring. |
| Reset Timeout | 140ms minimum (internal) or capacitor-adjustable - ensures sufficient hold time for slow-ramping supplies during cold start. |
| Watchdog Timeout | 1.6s typical (1.12–2.40s range) with 54s startup delay - prevents spurious resets during boot while detecting firmware hangs. |
| Supply Voltage Range | VCC = 1.0V to 5.5V - supports operation across legacy 5V and modern sub-1.2V logic domains. |
| Supply Current | 45–70µA at VCC = 2.5–5V - ultra-low quiescent current suitable for always-on supervisory functions. |
| Output Type | Open-drain with internal 30µA pullup - eliminates external resistors and allows level-shifting up to 5.5V. |
| Operating Temp | -40°C to +125°C - qualified for industrial and automotive under-hood environments. |
Pinout & Package
Package: 16-pin TQFN (4mm × 4mm), exposed pad (EP) connected to GND for thermal management. Pinout validated per Maxim's MAX16001 pin configuration diagram (TQFN top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 10, 11, 13, 14, 15 | IN1–IN4, MR, WDI, SRT | Input terminals: four monitored voltages, manual reset, watchdog input, and reset timeout capacitor connection. |
| 3, 4, 8, 9, 12, 16 | GND, VCC, OUT1–OUT4, RESET, TOL | Ground reference, unmonitored supply input, four independent monitor outputs, shared reset output, and threshold tolerance select. |
| 5–7 | OUT1, OUT2, OUT3 | Dedicated open-drain outputs tied to IN1–IN3 - provide per-rail fault indication without shared reset assertion. |
| 16 | TOL | Logic-level input selecting ±5% (GND) or ±10% (VCC) threshold accuracy - enables trade-off between noise immunity and precision. |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent voltage monitors | Enables discrete fault reporting per rail (e.g., detect 3.3V dropout without masking 1.8V fault), simplifying debug in complex power trees. |
| Capacitor-adjustable reset timeout | Supports custom timing from ~200µs to >3s using external SRT capacitor - accommodates diverse supply ramp profiles. |
| Integrated watchdog with 54s startup delay | Prevents false timeout during BIOS/post-boot initialization while ensuring runtime firmware lockup detection. |
| Margin enable input (MARGIN) | Active-low signal forcing all outputs high - allows safe voltage margin testing without triggering system reset. |
| Guaranteed operation down to VCC = 1V | Maintains correct logic state and supervision function during brownout or ultra-low-power sleep modes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16001ATE+ | AEC-Q100 qualified (-40°C to +125°C, automotive grade); identical pinout and electrical specs. | Required for automotive infotainment and ADAS ECUs needing automotive qualification. | Select MAX16001ATE+ when AEC-Q100 compliance is mandatory; MAX16001BTE+T suits industrial/server use. |
| TPS3808G33DBVR | Single 3.3V supervisor (not quad); no watchdog; 200ms fixed timeout; SOT-23-6 package. | Limited to single-rail monitoring; lacks independent outputs and adjustable thresholds. | Use only for simple 3.3V-only systems; not a functional replacement for quad-rail supervision. |
Compared with MAX16001ATE+, the MAX16001BTE+T offers identical supervision functionality but omits AEC-Q100 qualification, making it cost-optimized for non-automotive applications; compared with TPS3808G33DBVR, it provides four-rail monitoring, watchdog, and margin enable - features essential for complex multivoltage systems.

FAQ
What voltage rails does the MAX16001BTE+T monitor?
The MAX16001BTE+T monitors four voltage rails: IN1 = fixed 3.3V, IN2 = adjustable (0.366–0.400V), IN3 = adjustable, and IN4 = fixed 1.8V. Thresholds are selected via the TOL pin (±5% or ±10% tolerance), and each rail drives an independent open-drain output (OUT1–OUT4) plus a shared RESET signal. This configuration matches the MAX16001B variant defined in Table 1 of the datasheet.
Does the MAX16001BTE+T include a watchdog timer?
Yes, the MAX16001BTE+T includes a watchdog timer with a typical timeout period of 1.6s (1.12–2.40s range) and a 54s startup delay after reset. The timer clears on rising/falling edges of the WDI input and asserts RESET if no transition occurs within the timeout window. Leaving WDI unconnected disables the watchdog function entirely.
What is the reset timeout behavior of the MAX16001BTE+T?
The MAX16001BTE+T provides a minimum 140ms reset timeout when SRT is tied to VCC. For custom timing, connect a capacitor from SRT to GND; timeout is calculated as tRP = 2.06 MΩ × CSRT, supporting values from ~200µs (100pF) to >3s (1500pF). The RESET output remains asserted until all monitored voltages exceed thresholds and MR is deasserted.
How does the margin enable function work on the MAX16001BTE+T?
The MARGIN input on the MAX16001BTE+T is an active-low signal that forces all outputs (OUT1–OUT4 and RESET) into a high-impedance/high state when pulled low, regardless of input voltage conditions. This allows safe voltage margin testing - e.g., temporarily lowering a rail to verify trip point - without triggering system reset or false fault indications.
What package and footprint does the MAX16001BTE+T use?
The MAX16001BTE+T uses a 16-pin TQFN package measuring 4mm × 4mm with an exposed pad (EP) internally connected to GND. The land pattern number is 90-0070, outline number 21-0139, and package code T1644+4. Thermal performance is enhanced by soldering EP to the PCB ground plane.
