Product details
Overview
MAX16134MLG+T from Analog Devices is a precision triple-voltage microprocessor supervisor IC designed for automotive ADAS and multivoltage ASIC monitoring. It features three independent, factory-programmable input thresholds (1.0V–5.0V), ±1% window threshold accuracy over temperature, ±4% to ±11% programmable tolerance, 23 selectable reset timeout periods (20µs to 1200ms), and active-low open-drain reset outputs. It operates across -40°C to +125°C in an 8-pin SOT23 package.
For engineers reviewing the MAX16134MLG+T datasheet, MAX16134MLG+T pinout, MAX16134MLG+T application, or MAX16134MLG+T equivalent, this device delivers high-precision undervoltage/overvoltage window monitoring for safety-critical power-rail supervision in automotive and industrial embedded systems where functional safety and supply stability are paramount.
Technical Context
The MAX16134MLG+T implements independent window-comparator architecture per input channel, with each comparator featuring factory-trimmed UV/OV thresholds referenced to a stable internal voltage reference. Threshold hysteresis is fixed at either 0.25% or 0.50% of nominal input voltage, ensuring immunity to short-duration supply transients without compromising accuracy.
All three reset outputs share a single factory-set timeout period (here: 70ms, per suffix 'M'), assert on threshold violation, and remain asserted for the full timeout after return to valid window. The device guarantees correct logic state down to VDD = 1.07V and draws only 12.5µA typical supply current, enabling low-power system supervision.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Channels | Triple independent voltage monitor inputs (IN1, IN2, IN3) |
| Nominal Input Range | Factory-programmable from 1.0V to 5.0V per input - enables direct supervision of core, I/O, and auxiliary rails |
| Threshold Accuracy | ±1% over -40°C to +125°C - ensures reliable fault detection across full automotive temperature range |
| Window Tolerance | Programmable ±4% to ±11% - sets UV/OV trip points relative to nominal voltage (e.g., ±10% on 3.3V = 2.97V/3.63V) |
| Reset Timeout | 70ms minimum (suffix 'M') - provides sufficient hold time for µP initialization and power stabilization |
| Supply Current | 12.5µA typical - minimizes impact on battery-backed or ultra-low-power subsystems |

Pinout & Package
Package: 8-pin SOT23 (package code K8+5A), footprint compatible with JEDEC MO-178AB, thermal resistance θJA = 196°C/W on four-layer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Power supply input | Accepts 1.71V–5.5V; requires 0.1µF bypass capacitor to GND for noise immunity |
| 2 - IN1 | Monitoring input 1 | Connect to first nominal rail (e.g., 3.3V); asserts RESET1 if voltage falls outside programmed UV/OV window |
| 3 - IN2 | Monitoring input 2 | Connect to second nominal rail (e.g., 1.8V); asserts RESET2 independently upon window violation |
| 4 - GND | Ground reference | Common return path for all analog and digital circuitry; must be low-impedance |
| 5 - IN3 | Monitoring input 3 | Connect to third nominal rail (e.g., 1.2V); asserts RESET3 independently upon window violation |
| 6 - RESET3 | Active-low open-drain output | Drives low during IN3 fault; requires external pull-up resistor to system VDD or logic rail |
| 7 - RESET2 | Active-low open-drain output | Drives low during IN2 fault; shares same timeout as RESET1/RESET3 but operates independently |
| 8 - RESET1 | Active-low open-drain output | Drives low during IN1 fault; deasserts only after full 70ms timeout following return to valid window |

FAQ
What is the function of the MAX16134MLG+T in a power management system?
The MAX16134MLG+T serves as a triple-channel voltage supervisor that continuously monitors three independent supply rails for undervoltage and overvoltage conditions within a precise factory-programmed window. When any monitored input falls outside its set threshold boundaries, the corresponding active-low open-drain reset output asserts for a guaranteed 70ms minimum timeout period. This ensures reliable microprocessor or ASIC reset initiation before system-level instability occurs, making MAX16134MLG+T essential for robust power integrity in automotive and industrial applications.
How does the MAX16134MLG+T achieve ±1% threshold accuracy over temperature?
The MAX16134MLG+T achieves ±1% threshold accuracy over -40°C to +125°C through a combination of laser-trimmed internal voltage references, matched comparator architectures, and on-die temperature compensation circuitry. All threshold-setting components are co-located and thermally coupled on the die, minimizing drift-induced errors. This performance is validated across the full automotive temperature range and specified in the Electrical Characteristics table - not derived from extrapolation or typical-only data - ensuring MAX16134MLG+T meets functional safety requirements for ADAS and mission-critical embedded systems.
Can the reset timeout period of the MAX16134MLG+T be adjusted externally?
No, the reset timeout period of the MAX16134MLG+T is factory-programmed and fixed at 70ms (indicated by the 'M' suffix in the part number). It cannot be modified externally via resistors, capacitors, or digital interfaces. All three reset outputs (RESET1, RESET2, RESET3) share this identical timeout value. For designs requiring different timeout durations, alternate variants such as MAX16134Nxx+T (100ms) or MAX16134Kxx+T (40ms) must be selected - confirming that MAX16134MLG+T is optimized for applications where 70ms aligns precisely with processor boot timing requirements.
What are the absolute maximum ratings for the MAX16134MLG+T supply and input pins?
The MAX16134MLG+T has an absolute maximum VDD-to-GND rating of -0.3V to +6V, and each input pin (IN1, IN2, IN3) is rated from -0.3V to +6V relative to GND. Maximum continuous output sink current per reset pin is ±20mA, and junction temperature must not exceed +150°C. These ratings define electrical stress limits beyond which permanent damage may occur; normal operation is guaranteed only within the recommended operating conditions: VDD = 1.71V–5.5V, ambient temperature -40°C to +125°C, and input voltages within their programmed nominal ranges. Exceeding these limits invalidates MAX16134MLG+T reliability and warranty coverage.
Is the MAX16134MLG+T AEC-Q100 qualified, and what grade does it meet?
Yes, the MAX16134MLG+T is AEC-Q100 qualified and certified for Grade 0 (-40°C to +150°C junction) and Grade 1 (-40°C to +125°C ambient) operation. Its qualification includes stress testing for HTOL (High-Temperature Operating Life), TC (Temperature Cycling), AC (Autoclave), and ESD (Human Body Model ≥2kV, Charged Device Model ≥1kV). This certification confirms MAX16134MLG+T's suitability for automotive safety-critical applications including ADAS, powertrain, and body electronics where long-term reliability under harsh environmental conditions is mandatory.
