Product details
Overview
MAX16135ATI+T from Analog Devices is a quad-input, ±1% accurate, window voltage supervisor IC for automotive ADAS and multivoltage ASICs. It monitors four independent supply rails (e.g., 5.0V, 3.3V, 2.5V, 1.5V) for undervoltage/overvoltage faults with factory-programmable thresholds, 0.25% or 0.5% hysteresis, and a 20µs minimum reset timeout period. The device features dual active-low open-drain reset outputs (RESET1, RESET2), operates from 1.71V to 5.5V VDD, and is AEC-Q100 qualified for -40°C to +125°C operation.
For engineers reviewing the MAX16135ATI+T datasheet, MAX16135ATI+T pinout, MAX16135ATI+T application, or MAX16135ATI+T equivalent, key selection criteria include its quad-input window monitoring architecture, dual-reset logic mapping (IN1/IN2 → RESET1; IN3/IN4 → RESET2), ±1% threshold accuracy over temperature, SOT23-8 package compatibility, and support for functional safety–critical power sequencing in automotive electronics.
Technical Context
The MAX16135ATI+T implements a quad-input window supervision architecture where each input pair shares a reset output: RESET1 asserts when either IN1 or IN2 falls outside its programmed UV/OV window; RESET2 asserts when either IN3 or IN4 falls outside its window. All inputs use factory-trimmed reference-based comparators with ±1% accuracy across -40°C to +125°C.
It integrates a programmable reset timeout generator (20µs min) shared across both reset outputs, undervoltage lockout (UVLO) on VDD (1.35V–1.65V), and guaranteed correct reset state down to VDD = 1.07V. Input tolerance is factory-set from ±4% to ±11% in ±1% steps, with hysteresis options of 0.25% or 0.5% of VIN_NOM.

Use Scenario: Monitoring power rails for radar, camera, and LiDAR processors in a centralized ADAS domain controller. IC Role / Device Role / Timing Role: Quad-voltage supervisor ensuring all four ASIC supply domains (e.g., 5.0V analog, 3.3V I/O, 2.5V core, 1.5V memory) remain within ±1% window thresholds before releasing RESET1/RESET2. Use Value: Prevents partial initialization and metastability by enforcing strict simultaneous power-good validation across heterogeneous voltage domains. | Use Scenario: Coordinating startup sequence of a high-performance SoC with multiple internal voltage domains. IC Role / Device Role / Timing Role: Supervising pre-regulator, core, I/O, and auxiliary rails; asserting RESET1 until first two rails stabilize, then RESET2 until last two rails meet window criteria. Use Value: Enables deterministic, hardware-enforced power sequencing without firmware dependency - critical for fail-safe boot in safety-critical systems. |
| Automotive Infotainment Head Unit | Industrial Storage Controller |
Use Scenario: Validating 12V-to-5V, 5V-to-3.3V, 3.3V-to-1.8V, and 3.3V-to-1.2V DC/DC outputs powering display, audio, MCU, and connectivity subsystems. IC Role / Device Role / Timing Role: Detecting overvoltage on 5V rail (e.g., due to regulator fault) and undervoltage on 1.2V core rail simultaneously, triggering dual reset to isolate faulted sections. Use Value: Provides hardware-level fault containment - prevents cascading failures by halting execution before corrupted data propagates. | Use Scenario: Ensuring stable operation of NVMe SSD controller, DRAM buffer, flash interface, and PCIe PHY supplies in enterprise storage enclosures. IC Role / Device Role / Timing Role: Window-monitoring 3.3V (controller), 1.8V (DRAM), 1.2V (PHY), and 1.0V (flash I/O); asserting RESET2 only after all four rails settle within ±4% tolerance.

FAQ
What is the function of the dual reset outputs in MAX16135ATI+T?
The MAX16135ATI+T features two independent active-low open-drain reset outputs: RESET1 asserts when either IN1 or IN2 falls outside its factory-programmed undervoltage/overvoltage window, while RESET2 asserts when either IN3 or IN4 fails. This dual-output architecture enables hierarchical system reset partitioning - for example, holding application processors in reset until primary rails stabilize (via RESET1), then releasing peripherals only after secondary rails meet criteria (via RESET2). Each output requires an external pull-up resistor to a valid supply rail.
How does the MAX16135ATI+T achieve ±1% threshold accuracy over temperature?
The MAX16135ATI+T achieves ±1% threshold accuracy across -40°C to +125°C through factory trimming of internal voltage references and comparator offsets during production test. This calibration compensates for process variation and temperature-induced drift in the bandgap reference and input stage, eliminating the need for external calibration or software correction. The specification is guaranteed by design and verified across the full automotive temperature range, making MAX16135ATI+T suitable for safety-critical ADAS applications where precision voltage monitoring is mandatory.
What are the nominal input voltage options supported by MAX16135ATI+T?
The MAX16135ATI+T supports factory-programmable nominal input voltages from 1.0V to 5.0V per channel, with standard options including 5.0V, 3.3V, 2.5V, and 1.5V (as defined in the Quad-Nominal Input Selector Guide). For the specific MAX16135ATI+T variant, the ordering suffix "ATI" corresponds to IN1=5.0V, IN2=3.3V, IN3=2.5V, IN4=1.5V - enabling direct supervision of common multirail architectures without external scaling resistors or level shifters.
Does MAX16135ATI+T support overvoltage detection, and how is it configured?
Yes, MAX16135ATI+T provides true window supervision with both undervoltage and overvoltage detection on all four inputs. Overvoltage threshold is set as VIN_NOM × (1 + TOL%), where TOL is factory-programmed from ±4% to ±11% (e.g., ±4% yields OVT = 1.04 × VIN_NOM). The device uses internal precision comparators referenced to a trimmed bandgap, and OV detection is fully integrated - no external components or configuration registers are needed. This capability is confirmed in the Electrical Characteristics table and Functional Diagrams section of the datasheet.
What is the minimum reset timeout period available for MAX16135ATI+T?
The MAX16135ATI+T offers 23 factory-set reset timeout periods, with the shortest option being 20µs (indicated by suffix "A" in the part number). This minimum timeout is guaranteed over the full -40°C to +125°C operating range and is particularly valuable in fast-cycling automotive subsystems - such as radar front-ends or real-time motor controllers - where rapid power recovery and deterministic reset release are essential for meeting tight timing budgets.
