Product details

Overview

MAX16001DTE+T from Maxim Integrated is a quad-voltage microprocessor supervisor IC in a 16-pin TQFN (4mm × 4mm) package, monitoring four independent supply rails (e.g., 3.3V, 2.5V, adjustable, and 1.8V) with fixed or 5%/10% tolerance thresholds, 140ms minimum reset timeout, and integrated watchdog timer (1.6s typical timeout). It serves multivoltage ASICs and server power sequencing.

For engineers reviewing the MAX16001DTE+T datasheet, MAX16001DTE+T pinout, MAX16001DTE+T application, or MAX16001DTE+T equivalent, key selection criteria include quad-rail monitoring capability, AEC-Q100 qualification (DTE variant), open-drain outputs with internal 30µA pullups, capacitor-adjustable reset timeout, and watchdog startup delay of 54s after reset assertion.

Technical Context

The MAX16001DTE+T implements independent voltage monitoring per input with hysteresis (0.5% V_TH) and supports both fixed thresholds (3.3V, 2.5V, 1.8V) and adjustable thresholds down to 0.4V via external resistor divider. Its RESET output asserts low if any monitored voltage falls below its threshold or MR is pulled low, remaining asserted for ≥140ms after recovery.

It integrates a watchdog timer with 1.6s typical timeout and 54s startup delay, disabled when WDI is left floating. The device features manual reset (MR), margin enable (MARGIN), and tolerance select (TOL) inputs, all compatible with 0.3×V_CC/0.7×V_CC logic levels and internally pulled up (20kΩ).

Key Specifications

Parameter	Value and Actual Design Meaning
Monitored Voltages	Four independent rails: 3.3V, 2.5V, adjustable (down to 0.4V), and 1.8V - enables full power-rail supervision for complex SoC/FPGA systems.
Reset Timeout	Min 140ms (internal), adjustable up to ~3.92ms with 1500pF on SRT - ensures reliable system initialization timing across temperature (-40°C to +125°C).
Supply Voltage Range	V_CC = 1.0V to 5.5V - guarantees correct logic state down to 1V, supporting ultra-low-voltage operation and brownout resilience.
Watchdog Timeout	1.12s to 2.40s (typ 1.6s), with 35–72s startup delay - provides robust firmware hang detection while accommodating boot sequences.
Output Type	Open-drain RESET and four OUT_ outputs with internal 30µA pullups - eliminates need for external pullup resistors and reduces BOM count.
Threshold Tolerance	Selectable 5% (TOL = GND) or 10% (TOL = V_CC) - allows trade-off between noise immunity and margin testing flexibility.
Supply Current	45–70µA at V_CC = 2.5V–5V - enables low-power always-on supervision in battery-backed or energy-sensitive applications.

Pinout & Package

MAX16001DTE+T uses a 16-pin TQFN package (4mm × 4mm, exposed pad), RoHS-compliant, rated for -40°C to +125°C operation. Pin 1 is IN2; pin 16 is TOL. Exposed pad (EP) is internally connected to GND and must be soldered to PCB ground plane for thermal management.

Pin/Terminal	Circuit Role	Design Meaning
1	IN2	Second monitored input (e.g., 2.5V rail); falling-edge threshold detection with 0.5% hysteresis.
2	IN1	First monitored input (e.g., 3.3V rail); supports fixed or adjustable threshold configuration.
3	RESET	Active-low open-drain reset output; asserts when any IN_ fails or MR is pulled low; internal 30µA pullup.
4	MARGIN	Active-low margin enable input; deasserts all outputs during functional margin testing without affecting rail status.
5	IN3	Third monitored input (adjustable threshold); accepts external resistor divider for custom voltage monitoring.
6	IN4	Fourth monitored input (e.g., 1.8V rail); independently latched and debounced.
7	GND	Ground reference for all analog and digital circuitry; connects to EP for thermal conduction.
8	VCC	Unmonitored supply input (1.0V–5.5V); powers internal circuitry and provides pullup reference for open-drain outputs.
9	WDI	Watchdog timer input; edge-triggered; floating disables watchdog; leakage <1µA ensures low power.
10	MR	Active-low manual reset input; internally pulled up to VCC (20kΩ); 1µs minimum pulse width.
11	SRT	Set-reset timeout input; connect capacitor to GND to extend timeout beyond 140ms; 460–740nA ramp current.
12	TOL	Tolerance select input; GND = 5%, VCC = 10% threshold accuracy - configures noise immunity vs. margin test headroom.
13–15	OUT1–OUT3	Independent open-drain outputs for IN1–IN3; each has internal 30µA pullup and 20µs propagation delay.
16	OUT4	Independent open-drain output for IN4; identical electrical specs to OUT1–OUT3.

Key Features

Feature	Design Value
Quad independent voltage monitors	Each IN_ input has dedicated threshold detection and latch, enabling per-rail fault isolation in multivoltage systems.
Capacitor-adjustable reset timeout	SRT pin supports precise timeout tuning (140ms to >3ms) using external capacitor - replaces fixed RC networks with single-component adjustment.
Integrated watchdog with startup delay	54s startup window prevents false resets during long boot sequences while maintaining post-boot firmware supervision.
Internal 30µA output pullups	Eliminates four external pullup resistors; outputs drive up to 5.5V externally - simplifies level-shifting and reduces board area.
AEC-Q100 qualified (DTE variant)	Qualified for automotive-grade reliability (Grade 0: -40°C to +125°C), enabling use in ADAS and infotainment power management.

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+T	Same functionality and pinout; differs only in tape-and-reel packaging (ATE vs DTE) and RoHS suffix (+T vs +T).	No functional difference; both qualified for -40°C to +125°C operation and AEC-Q100.	Select MAX16001ATE+T for automated placement where tape format differs; electrical and thermal specs are identical.
TPS3307-33D	Triple-supervisor (not quad); fixed 3.3V/3.0V/2.5V thresholds; no adjustable input or watchdog timer.	Lacks fourth rail monitoring, margin enable, and watchdog - unsuitable for systems requiring four independent rails or firmware supervision.	Choose only if design uses exactly three rails and does not require watchdog or adjustable thresholds.

Compared with MAX16001ATE+T, the MAX16001DTE+T offers identical supervision functionality but optimized for different packaging logistics; versus TPS3307-33D, it adds a fourth rail, adjustable threshold, watchdog, and margin enable - making it essential for complex multivoltage ASICs and automotive-grade servers.

FAQ

What is the function of the MARGIN pin on the MAX16001DTE+T?

The MARGIN pin on the MAX16001DTE+T is an active-low input that deasserts all outputs (drives them high) regardless of monitored voltage states, enabling safe margin testing of power supplies without triggering false resets. When pulled low, it overrides the normal supervision logic, allowing engineers to verify system behavior under controlled voltage deviations. This function is critical for validating power integrity in high-reliability applications like servers and automotive modules using the MAX16001DTE+T.

Does the MAX16001DTE+T support adjustable voltage thresholds?

Yes, the MAX16001DTE+T supports adjustable thresholds on IN3 (and optionally IN4 depending on variant), allowing monitoring of voltages as low as 0.4V using an external resistor divider. The datasheet specifies fixed thresholds for IN1 (3.3V), IN2 (2.5V), and IN4 (1.8V), while IN3 is designated as adjustable in the MAX16001D variant. This flexibility enables custom rail supervision in advanced ASIC and FPGA designs where nonstandard core voltages are used, extending the utility of the MAX16001DTE+T beyond standard supply rails.

What is the watchdog startup delay for the MAX16001DTE+T?

The MAX16001DTE+T watchdog timer features a 54-second startup delay after reset assertion, allowing sufficient time for system boot and firmware initialization before watchdog supervision begins. This delay prevents spurious resets during lengthy boot sequences common in servers and telecom equipment. Once the delay expires, the watchdog actively monitors WDI transitions, resetting the system if no valid edge occurs within the 1.12–2.40s timeout window. This behavior is confirmed in the MAX16001DTE+T datasheet and applies specifically to this variant.

Is the MAX16001DTE+T AEC-Q100 qualified?

Yes, the MAX16001DTE+T is explicitly AEC-Q100 qualified (Grade 0, -40°C to +125°C), as stated in the official Maxim Integrated datasheet. This qualification confirms its suitability for automotive applications including ADAS, infotainment, and body control modules where reliability under extreme thermal and electrical stress is mandatory. The "DTE" suffix denotes the AEC-Q100–qualified version, distinguishing it from non-automotive variants like MAX16001TTE+T.

How does the SRT pin adjust the reset timeout on the MAX16001DTE+T?

The SRT pin on the MAX16001DTE+T adjusts reset timeout by accepting an external capacitor connected to GND; the timeout period is calculated as t_RP = 2.06 × 10⁶ Ω × C_SRT (F), yielding values from 140ms (SRT = V_CC) up to ~3.92ms (1500pF). This capacitor-based method replaces fixed RC networks with a single passive component, simplifying layout and enabling precise timing calibration. The SRT ramp current (460–740nA) and threshold (1.173–1.293V) are tightly specified to ensure accuracy across temperature, a key design feature of the MAX16001DTE+T.
