Product details
Overview
MAX16134QAA+T from Analog Devices is a precision quad-voltage microprocessor supervisor IC designed for automotive ADAS systems. It monitors four independent supply rails (IN1–IN4) with ±1% threshold accuracy over -40°C to +125°C, supports factory-programmable window thresholds (±4% to ±11%), and delivers 200ms minimum reset timeout via active-low open-drain outputs. Its SOT23-8 package enables compact integration in multivoltage ASICs and storage equipment.
For engineers reviewing the MAX16134QAA+T datasheet, MAX16134QAA+T pinout, MAX16134QAA+T application, or MAX16134QAA+T equivalent, this device is selected for high-reliability voltage monitoring where tight window detection, functional safety compliance (AEC-Q100), and immunity to short transients are required in automotive and industrial embedded systems.
Technical Context
The MAX16134QAA+T implements independent undervoltage/overvoltage window comparators per input channel, each with factory-trimmed hysteresis (0.25% or 0.5%) and ±1% threshold accuracy across temperature. Its internal voltage reference and trimming architecture ensures stable monitoring without external components.
All four inputs (IN1–IN4) are monitored simultaneously against user-configured nominal voltages (1.0V–5.0V) and tolerance bands; reset assertion occurs when any input breaches its window, and deassertion follows a fixed 200ms timeout period after re-entry-guaranteed correct logic state down to VDD = 1.07V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Channels | Quad (IN1–IN4), independently monitored with dedicated reset logic |
| Threshold Accuracy | ±1% over -40°C to +125°C - enables precise fault detection without calibration |
| Window Tolerance Range | Factory-programmable ±4% to ±11% - sets UV/OV trip points relative to nominal input |
| Reset Timeout | 200ms minimum - ensures reliable system reset hold time after fault clearance |
| Supply Current | 12.5μA typical - ultra-low power for always-on monitoring in battery-sensitive systems |
| Operating Voltage | 1.71V to 5.5V - compatible with modern low-voltage SoCs and legacy 3.3V/5V rails |
| Output Type | Active-low, open-drain - allows wired-OR configuration and flexible pull-up voltage selection |
Pinout & Package
MAX16134QAA+T is housed in an 8-pin SOT23 package (outline 21-0078, land pattern 90-0176), optimized for space-constrained automotive PCB layouts and qualified per AEC-Q100 Grade 0.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VDD | Power supply input | Bypassed with 0.1µF capacitor to GND; UVLO ensures valid reset state above 1.07V |
| 2 - IN3 | Third monitoring input | Connected to nominal supply rail; triggers RESET3 if voltage falls outside programmed window |
| 3 - IN1 | First monitoring input | Primary rail monitor; asserts RESET1 on UV/OV event per factory-set thresholds |
| 4 - GND | Ground reference | Common return path for all analog and digital circuitry; critical for noise immunity |
| 5 - IN2 | Second monitoring input | Independent rail monitor; RESET2 asserted only when IN2 violates its window |
| 6 - IN4 | Fourth monitoring input | Enables full quad-rail supervision; RESET2 also responds to IN4 per MAX16134 dual-reset architecture |
| 7 - RESET3 | Active-low open-drain output | Drives external reset line; requires external pull-up resistor to host VDD |
| 8 - RESET1 | Active-low open-drain output | Dedicated reset for IN1; shares 200ms timeout with all other reset outputs |
Key Features
| Feature | Design Value |
|---|---|
| Quad independent monitoring | Simultaneous real-time supervision of four distinct supply domains without shared thresholds |
| ±1% threshold accuracy over temp | Eliminates need for external calibration or margining in automotive-grade designs |
| 23 selectable reset timeouts | 200ms option (suffix Q) provides robust hold time for complex processor boot sequences |
| Immunity to short supply transients | Internal comparator hysteresis (0.25%/0.5%) rejects noise spikes ≤15µs without false resets |
| AEC-Q100 qualified | Validated for automotive use at -40°C to +125°C junction temperature |
Applications
| ADAS Domain Controller | Multivoltage ASIC Power Sequencing |

IC Role / Device Role / Timing Role: Window-based supervision detects both under- and overvoltage faults before they damage downstream logic. Use Value: Supports functional safety requirements (IEC 61508 SIL-2) via deterministic reset behavior and ±1% accuracy traceability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16135QAA+T | Dual-reset architecture (RESET1 for IN1/IN2, RESET2 for IN3/IN4); same quad-input capability but grouped outputs | Preferred when system-level reset grouping simplifies board routing or reduces external logic | Select MAX16135QAA+T only if dual-output grouping aligns with system reset tree topology |
| TPS3808G33DBVR | Single-channel supervisor with 3.3V fixed threshold; no window monitoring or quad capability | Limited to single-rail applications; lacks UV/OV window detection and multi-supply coordination | Use only for simple 3.3V monitoring where quad supervision and window accuracy are not required |
Compared with MAX16135QAA+T, the MAX16134QAA+T provides fully independent reset outputs per input-critical for systems requiring granular fault isolation. Versus TPS3808G33DBVR, it delivers quad-channel window supervision with ±1% accuracy, enabling higher system reliability in multivoltage automotive electronics.

FAQ
What is the nominal input voltage configuration for MAX16134QAA+T?
The MAX16134QAA+T is configured with IN1 = 3.300V, IN2 = 1.800V, IN3 = 1.160V, and IN4 = 1.160V per its Q suffix in the Selector Guide. These values are factory-programmed and define the center points for undervoltage and overvoltage window thresholds across all four inputs.
How does the reset timeout period work on MAX16134QAA+T?
The MAX16134QAA+T features a fixed 200ms minimum reset timeout period (suffix Q). All four reset outputs share this identical timeout value. After any input exits its window threshold, the corresponding reset output remains asserted for ≥200ms, then deasserts only after the input returns within the window and the full timeout elapses.
Is MAX16134QAA+T AEC-Q100 qualified?
Yes, MAX16134QAA+T is AEC-Q100 qualified for Grade 0 (-40°C to +125°C ambient operation). This qualification covers stress testing, reliability validation, and thermal cycling specific to automotive electronic control units, confirming suitability for ADAS and powertrain applications.
What is the function of the open-drain reset outputs on MAX16134QAA+T?
The MAX16134QAA+T provides three active-low open-drain reset outputs (RESET1, RESET3, and RESET2 which serves IN3/IN4). Each requires an external pull-up resistor to the host supply rail. This architecture enables wired-OR connections, level translation, and compatibility with diverse processor reset input requirements.
Can unused inputs on MAX16134QAA+T be left floating?
No. Unused inputs on MAX16134QAA+T must be connected to their nominal voltage setting (e.g., via a resistor divider or clean supply rail) to prevent false resets. Floating inputs introduce noise susceptibility and violate the device's specified operating conditions, risking unreliable window monitoring behavior.
