Product details
Overview
MAX16193ATA00/VY+T from Analog Devices is a dual-channel, ±0.3% accurate window-detecting supervisory circuit that monitors core (0.9V) and I/O (3.28V) supply rails for undervoltage/overvoltage faults in automotive ADAS and FPGA systems. It features open-drain reset outputs, 10ms factory-set timeout, and operates from -40°C to +125°C in an AEC-Q100-qualified side-wettable TDFN package.
For engineers reviewing the MAX16193ATA00/VY+T datasheet, MAX16193ATA00/VY+T pinout, MAX16193ATA00/VY+T application, or MAX16193ATA00/VY+T equivalent, this page delivers verified threshold accuracy (±0.3%), IN1/IN2 voltage ranges (0.9V/3.28V), reset timing (10ms), automotive qualification status, and side-wettable flanks package details required for functional safety-critical power monitoring designs.
Technical Context
The MAX16193ATA00/VY+T implements two independent, factory-trimmed window comparators with ±0.3% threshold accuracy over -40°C to +125°C, supporting ±4%/±3% UV/OV tolerance on IN1 (0.9V) and IN2 (3.28V). Each channel drives an active-low, open-drain reset output with 10ms timeout after fault recovery.
Its BiCMOS process enables low quiescent current (50–100µA), 1.7V–5.5V VDD operation, and input bias currents of 3–6µA (IN1) and 6–12µA (IN2), ensuring minimal loading on precision low-voltage rails while maintaining noise immunity via 0.15% hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IN1 Threshold | 0.9V nominal, ±4% UV/OV window - matches typical 0.9V core rail with 3.6% margin |
| IN2 Threshold | 3.28V nominal, ±3% UV/OV window - targets 3.3V I/O supply with 98.4mV guardband |
| Threshold Accuracy | ±0.3% over full temperature and supply range - ensures reliable fault detection without calibration |
| Reset Timeout | 10ms factory-set - guarantees sufficient hold time for microcontroller initialization |
| Reset Output Type | Active-low open-drain - requires external pull-up; supports wired-OR reset bus architectures |
| Operating Temp | -40°C to +125°C - validated for under-hood automotive environments per AEC-Q100 Grade 0 |
| Supply Range | VDD = 1.7V to 5.5V - powers from same rail as monitored system or auxiliary LDO |
Pinout & Package
MAX16193ATA00/VY+T uses an 8-pin, 2mm × 3mm side-wettable flanks TDFN package (T823Y+3C) with exposed pad (EP) internally connected to GND. The package meets AEC-Q100 requirements and supports automated optical inspection (AOI) of solder joints on automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Power supply input | Accepts 1.7V–5.5V; must be bypassed with 0.1µF capacitor near pin for noise immunity |
| IN1 (Pin 2) | Core rail monitor input | Monitors 0.9V nominal supply; ±4% window with ±0.3% accuracy enables precise low-voltage fault detection |
| GND (Pin 3) | Ground reference | Primary ground return; EP must also connect to GND plane for thermal and EMI performance |
| IN2 (Pin 4) | I/O rail monitor input | Monitors 3.28V nominal supply; ±3% window ensures robustness against 3.3V rail variation |
| N.C. (Pins 5,6) | No-connect terminals | Not bonded; must remain unconnected to avoid parasitic coupling or latch-up risk |
| RST2 (Pin 7) | Active-low open-drain reset output 2 | Asserts low during IN2 fault; requires 10kΩ pull-up to system VCC for proper logic level |
| RST1 (Pin 8) | Active-low open-drain reset output 1 | Asserts low during IN1 fault; independently controlled; shares no internal logic with RST2 |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent window detectors | Enables simultaneous monitoring of core and I/O rails without shared timing or threshold dependencies |
| ±0.3% threshold accuracy over temp | Eliminates need for system-level calibration across -40°C to +125°C in automotive applications |
| Side-wettable flanks package | Supports automated X-ray and AOI inspection of solder joints for zero-defect automotive manufacturing |
| AEC-Q100 qualified | Validated for automotive use including stress testing, lifetime reliability, and failure mode analysis |
| Factory-programmed 10ms timeout | Guarantees consistent reset assertion duration without external RC components or configuration registers |
Applications
| ADAS Power Monitoring | FPGA Configuration Supervision |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16193BATA00+T | Same IN1/IN2 thresholds (0.9V/3.28V), ±4%/±3% tolerance, and ±0.3% accuracy; differs only in package (T823+3C, non-side-wettable) | Industrial-grade only; not AEC-Q100 qualified or automotive-qualified | Select for cost-sensitive industrial PLCs where AOI inspection is not required. |
| TLV809E33DBVR | Single-channel 3.3V supervisor with ±1% threshold accuracy, 200ms timeout, SOT-23-3 package; no IN1 capability or window detection | Lacks dual-rail monitoring, accuracy, and automotive qualification; suitable only for basic single-rail reset | Use only if monitoring one rail at lower accuracy is sufficient and AEC-Q100 compliance is unnecessary. |
Compared with MAX16193BATA00+T, the MAX16193ATA00/VY+T adds side-wettable flanks and AEC-Q100 qualification for automotive AOI and reliability, while TLV809E33DBVR offers no functional equivalence-lacking dual channels, window detection, or sub-1% accuracy-making it unsuitable for safety-critical multi-rail systems.

FAQ
What is the exact IN1 and IN2 threshold voltage for MAX16193ATA00/VY+T?
The MAX16193ATA00/VY+T has factory-programmed nominal thresholds of 0.9V on IN1 and 3.28V on IN2, with ±4% and ±3% UV/OV windows respectively. These values are fixed per the ordering code and confirmed in the Selector Guide Table of the official datasheet. The ±0.3% accuracy applies across -40°C to +125°C and 1.7V–5.5V VDD range. No external programming or resistor networks are needed to set these thresholds in the MAX16193ATA00/VY+T.
Is MAX16193ATA00/VY+T pin-compatible with other MAX16193 variants?
Yes, all MAX16193 variants-including MAX16193ATA00/VY+T, MAX16193BATA00+T, and MAX16193CATA00+T-share identical 8-pin TDFN pinouts and footprint (T823Y+3C or T823+3C). However, MAX16193ATA00/VY+T uses the side-wettable flanks variant (T823Y+3C), while others use standard T823+3C. Electrical pin functions are fully identical; only package construction and qualification differ.
Does MAX16193ATA00/VY+T support push-pull reset outputs?
No, MAX16193ATA00/VY+T is factory-configured with open-drain reset outputs (RST1 and RST2). The push-pull option is available only in the MAX16193CATA00+T variant. For MAX16193ATA00/VY+T, each reset output requires an external 10kΩ pull-up resistor to the appropriate system rail, as specified in the Pin Descriptions section of the datasheet.
What is the reset timeout period for MAX16193ATA00/VY+T?
The MAX16193ATA00/VY+T has a factory-set reset timeout period of 10ms. This is the duration RST1 or RST2 remains asserted low after the corresponding monitored rail (IN1 or IN2) returns within its undervoltage/overvoltage window. The timeout accuracy is ±20% over temperature and supply, and no external components or configuration are required to achieve this timing in the MAX16193ATA00/VY+T.
How does the side-wettable flanks feature benefit MAX16193ATA00/VY+T in automotive production?
The side-wettable flanks on the MAX16193ATA00/VY+T package enable automated optical inspection (AOI) of solder joint quality on the PCB's edge, a critical requirement for zero-defect automotive manufacturing. Unlike standard TDFN packages, the exposed vertical metal sidewalls allow machine vision systems to verify reflow integrity without X-ray, directly supporting AEC-Q100 process reliability and IATF 16949 compliance in high-volume ADAS ECU production.
