Product details
Overview
MAX16193CATA00+T from Analog Devices is a dual-channel, ±0.3% accurate window-detecting supervisory circuit that monitors core (0.6V–0.9V) and I/O (0.9V–3.3V) supply rails for undervoltage/overvoltage faults in automotive ADAS and FPGA-based systems. It features push-pull active-low reset outputs, 10ms factory-set reset timeout, and operates from -40°C to +125°C in an 8-pin TDFN package.
For engineers reviewing the MAX16193CATA00+T datasheet, MAX16193CATA00+T pinout, MAX16193CATA00+T application, or MAX16193CATA00+T equivalent, key selection criteria include its ±0.3% threshold accuracy across temperature, push-pull RST output configuration (no external pull-up required), 0.9V/3.280V nominal input thresholds with ±4%/±3% UV/OV tolerance, and AEC-Q100-qualified side-wettable flanks package compatibility.
Technical Context
The MAX16193CATA00+T implements two independent voltage monitoring channels with factory-trimmed nominal thresholds (IN1 = 0.9V, IN2 = 3.280V) and programmable UV/OV windows (±4% on IN1, ±3% on IN2). Each channel uses precision bandgap references and comparator circuitry to achieve ±0.3% threshold accuracy over -40°C to +125°C.
Its push-pull reset outputs (RST1, RST2) drive low during fault conditions and return high after a fixed 10ms timeout when inputs re-enter their valid windows. The device incorporates undervoltage lockout (1.5V typical) and draws only 50–100µA quiescent current, enabling reliable supervision in low-power automotive and industrial embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16193ATA00/VY+T | Open-drain RST outputs; side-wettable flanks package (T823Y+3C); same thresholds and accuracy | Requires external 10kΩ pull-up resistors; suited for legacy designs with existing open-drain reset bus architecture | Select when interoperability with existing open-drain reset buses is required and AOI capability is needed. |
| TPS389033DSER | Single-channel, 0.5% accuracy, 3.3V fixed threshold; SOT-23-6; no IN1 core-rail option | Lacks dual-rail capability and sub-1V monitoring; limited to I/O rail supervision only | Consider only for cost-sensitive, single-rail applications where core rail supervision is handled separately. |
Compared with MAX16193ATA00/VY+T, the MAX16193CATA00+T removes pull-up dependencies and simplifies layout but lacks side-wettable flanks for AOI. Against TPS389033DSER, it delivers true dual-rail supervision with higher accuracy and core-rail support-making it irreplaceable in multivoltage safety-critical systems.

FAQ
What is the nominal input voltage configuration for MAX16193CATA00+T?
The MAX16193CATA00+T is factory-configured with IN1 nominal threshold at 0.9V (±4% UV/OV window) and IN2 at 3.280V (±3% UV/OV window). These values are laser-trimmed and specified in the Selector Guide Table of the datasheet. The ±0.3% accuracy applies across the full -40°C to +125°C operating range, making MAX16193CATA00+T suitable for high-reliability automotive and industrial applications where voltage margining is critical.
Does MAX16193CATA00+T require external pull-up resistors on its reset outputs?
No, MAX16193CATA00+T features push-pull active-low reset outputs (RST1 and RST2), eliminating the need for external pull-up resistors. This contrasts with open-drain variants like MAX16193ATA00/VY+T. The push-pull configuration ensures fast, low-impedance high-state transitions without relying on external components, simplifying PCB layout and improving noise immunity in dense automotive electronics. MAX16193CATA00+T's internal driver is rated for VOH ≥ 0.8×VDD and VOL ≤ 0.1V.
What is the reset timeout period for MAX16193CATA00+T, and is it adjustable?
The MAX16193CATA00+T has a factory-set reset timeout period of 10ms - the time between fault clearance and reset deassertion. This value is non-adjustable and laser-trimmed during production. The timeout begins once the monitored input voltage returns within its programmed UV/OV window and is guaranteed to be within ±20% tolerance. This fixed timing ensures predictable power-up sequencing in FPGAs and microcontrollers without external RC networks, a key design advantage of MAX16193CATA00+T.
Is MAX16193CATA00+T qualified for automotive applications?
Yes, MAX16193CATA00+T is AEC-Q100 qualified and packaged in an 8-pin TDFN (T823+3C) with side-wettable flanks - though not the Y-suffix variant (which denotes side-wettable flanks explicitly). Its -40°C to +125°C operating range, ±0.3% threshold accuracy over temperature, and robust ESD/latch-up performance meet automotive functional safety requirements. While MAX16193ATA00/VY+T offers enhanced AOI capability via side-wettable flanks, MAX16193CATA00+T remains fully qualified for automotive use in ADAS and body control modules.
How does the hysteresis function in MAX16193CATA00+T, and what is its value?
MAX16193CATA00+T incorporates 0.15% of threshold voltage hysteresis on both IN1 and IN2 inputs to prevent chatter near trip points caused by noise or slow-moving supply ramps. For example, with IN2 = 3.280V, hysteresis is 3.280V × 0.15% ≈ 4.92mV. This small, fixed hysteresis is factory-trimmed and contributes to stable fault detection without requiring external components. The hysteresis improves noise immunity while maintaining the ±0.3% overall threshold accuracy specification of MAX16193CATA00+T.
