Product details
Overview
MAX16160NCAB+T from Maxim Integrated is a high-accuracy, four-channel supervisory IC that monitors IN2/VCC (1.7V–5.5V), IN1, IN3, and IN4 supply rails with ±1% threshold accuracy across -40°C to +125°C, asserts active-low open-drain RESET on any undervoltage event, and features 18μA internal pullup to IN2/VCC-used in multi-rail server power sequencing.
For engineers reviewing the MAX16160NCAB+T datasheet, MAX16160NCAB+T pinout, MAX16160NCAB+T application, or MAX16160NCAB+T equivalent, key selection criteria include guaranteed reset assertion for any input >1V during power-up, fixed/adjustable threshold options per channel, 20μs input-to-reset delay, 17μA quiescent current, and WLP package thermal resistance of 95.15°C/W.
Technical Context
The MAX16160NCAB+T implements independent voltage comparators per input with programmable hysteresis (0.25% or 0.5%), a precision bandgap reference, and a reset timeout timer whose period is factory-set (here: 140ms). Its power-up detection logic asserts RESET when any monitored input exceeds 1V before reaching its trip threshold.
It supports both fixed-threshold monitoring (IN1/IN3/IN4: 0.5V–5V in ~20mV steps; IN2/VCC: 1.76V–5V) and adjustable-threshold operation via external resistor dividers (0.62V internal reference), with all inputs validated for ±1% accuracy over full temperature and supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | IN2/VCC = 1.7V to 5.5V - powers device and serves as reference for internal pullup and comparator operation |
| Threshold Accuracy | ±1% over -40°C to +125°C - ensures reliable reset assertion without calibration across industrial temperature range |
| Quiescent Current | 17μA typical - enables low-power system supervision without burdening standby rail |
| Reset Timeout Period | 140ms - provides sufficient hold time for microcontroller initialization after all supplies stabilize |
| Input-to-Reset Delay | 20μs - guarantees fast response to supply faults while rejecting sub-20μs transients |
| RESET Output Type | Active-low open-drain with 18μA internal pullup to IN2/VCC - eliminates external pullup resistor in most 3.3V/5V systems |
| Input Hysteresis | 0.25% (MAX16160___B variant) - suppresses false resets from noise on monitored rails without degrading threshold precision |
Pinout & Package
MAX16160NCAB+T is packaged in a 6-bump Wafer-Level Package (WLP), outline number 21-100366, with land pattern 90-0175, RoHS-compliant, and thermal resistance θJA = 95.15°C/W on a four-layer board.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B1 (Pin 1) | IN1 | Monitoring input 1 - accepts fixed-threshold (0.5V–5V) or adjustable-threshold (via 0.62V reference + resistor divider) supply rail |
| B2 (Pin 2) | IN2/VCC | Power supply input and monitoring input - powers IC and sets internal pullup voltage; requires 0.1μF bypass capacitor to GND |
| B3 (Pin 3) | IN3 | Monitoring input 3 - functionally identical to IN1, supports same fixed/adjustable threshold configurations |
| A3 (Pin 4) | IN4 | Monitoring input 4 - identical to IN1/IN3; all three inputs share ±1% accuracy and 20μs response timing |
| A2 (Pin 5) | GND | Analog ground reference - must be connected to system ground plane with low-impedance path for stable comparator operation |
| A1 (Pin 6) | RESET | Active-low open-drain output - asserts low on any undervoltage condition; internally pulled up to IN2/VCC at 18μA |
Key Features
| Feature | Design Value |
|---|---|
| Any-input power-up reset guarantee | Asserts RESET low if any monitored input exceeds 1V before reaching trip threshold - prevents premature MCU release during brown-in |
| Internal 18μA pullup to IN2/VCC | Eliminates need for external pullup resistor in standard 3.3V/5V systems - reduces BOM count and layout area |
| 0.25% input hysteresis option | Rejects short-duration supply transients (<100ns) without compromising ±1% threshold accuracy - improves noise immunity in noisy environments |
| Four independent monitoring channels | Simultaneously supervises core, I/O, analog, and auxiliary rails - replaces multiple discrete supervisors in multi-supply systems |
| Fixed and adjustable threshold flexibility | IN1/IN3/IN4 support either factory-set thresholds (0.5V–5V) or user-configurable thresholds via resistor dividers - simplifies design reuse across voltage variants |
Applications
| Server Power Sequencing | Industrial PLC Power Monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar four-channel supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16161NCAB+T | Same pinout and package, but 0.5% hysteresis (vs. 0.25% in MAX16160NCAB+T); identical threshold accuracy and timeout | Better suited for systems with slower-rising supplies where larger hysteresis prevents chatter; same thermal performance and quiescent current | Select MAX16161NCAB+T if system supply ramps exceed 100mV/ms and noise margin >0.5% is required |
| TPS3808G33DBVR | Three-channel supervisor (not four); fixed 3.3V threshold only on VDD; no adjustable inputs; 2.9μA ICC vs. 17μA | Limited to simpler 3-rail systems; lacks IN1/IN3/IN4 flexibility and 1V power-up assertion logic | Choose only when monitoring exactly three fixed-voltage rails and ultra-low ICC is mandatory - not a functional replacement |
Compared with MAX16160NCAB+T, MAX16161NCAB+T trades finer hysteresis resolution for enhanced noise rejection, while TPS3808G33DBVR offers lower power but sacrifices channel count, threshold flexibility, and power-up behavior - making MAX16160NCAB+T optimal for complex, thermally constrained, multi-rail systems requiring deterministic reset timing.

FAQ
What is the reset timeout period for MAX16160NCAB+T?
The MAX16160NCAB+T has a factory-set reset timeout period of 140ms. This duration begins after all monitored inputs rise above their respective threshold voltages and ensures the RESET signal remains asserted long enough for microcontrollers and FPGAs to complete internal initialization before deassertion. The timeout accuracy is specified as -40% to +30% over temperature.
Does MAX16160NCAB+T require an external pullup resistor on the RESET pin?
No, MAX16160NCAB+T does not require an external pullup resistor on the RESET pin because it integrates an 18μA (typical) internal pullup current to IN2/VCC. This feature eliminates the need for external components in most 3.3V or 5V systems. An external pullup may be added only if interfacing to a logic supply different from IN2/VCC.
Can MAX16160NCAB+T monitor a 1.0V supply rail?
Yes, MAX16160NCAB+T can monitor a 1.0V supply rail using its adjustable-threshold capability on IN1, IN3, or IN4. Each of these inputs has an internal 0.62V reference; applying a resistor divider (e.g., R1 = 69.8kΩ, R2 = 10kΩ) scales the 1.0V input to match the 0.62V threshold, enabling precise undervoltage detection at ±1% accuracy.
What package type is used for MAX16160NCAB+T?
MAX16160NCAB+T uses a 6-bump Wafer-Level Package (WLP), outline number 21-100366, with dimensions of 0.8mm × 0.8mm and a pitch of 0.4mm. This ultra-compact RoHS-compliant package provides θJA = 95.15°C/W on a four-layer board and is optimized for space-constrained applications like notebooks and networking modules.
How does MAX16160NCAB+T behave during power-up when supply voltages are ramping?
During power-up, MAX16160NCAB+T asserts RESET low whenever any monitored input exceeds 1V-even before reaching its final trip threshold. This "any-input >1V" behavior ensures the microcontroller remains held in reset until all rails begin ramping reliably, preventing erratic boot sequences caused by partial power application or brown-in conditions.
