Product details
Overview
MAX16162NDK300+ from Analog Devices is a nanoPower supply supervisor IC designed for glitch-free power-up in ultra-low-voltage systems. It monitors VIN (0.6V–4.85V threshold), asserts an active-low open-drain RST output, guarantees reset assertion down to 0V VCC, and provides a factory-set 300ms reset timeout period. It is used to ensure reliable boot sequencing of low-voltage FPGA cores and microcontrollers in battery-powered wearables.
For engineers reviewing the MAX16162NDK300+ datasheet, MAX16162NDK300+ pinout, MAX16162NDK300+ application, or MAX16162NDK300+ equivalent, key selection considerations include its 0.6V minimum monitoring voltage, 825nA typical quiescent current, guaranteed reset assertion at 0V VCC, 4-bump WLP package (1.06mm × 0.73mm), and absence of manual reset input - distinguishing it from the MAX16161 family.
Technical Context
The MAX16162NDK300+ implements a dedicated VIN monitoring path separate from VCC, enabling supervision of sub-1V core supplies while operating from a higher VCC rail (1.7V–5.5V). Its internal reference and timer circuitry guarantee RST remains asserted until VIN exceeds VTH + VHYS (1% hysteresis) and the full 300ms timeout elapses - eliminating undefined reset states during slow or noisy power ramps.
Unlike conventional supervisors, it sinks RST current even when VCC = 0V, ensuring no power-up glitch. The device uses no internal MR logic or debounce circuitry (as it lacks MR), and its reset timeout is fixed by the "300" suffix per Table 1 - eliminating configuration pins or external components for timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold Voltage | 3.00V ±1.5% - factory-trimmed for precise brownout detection of 3.0V system rails |
| Quiescent Current | 825nA typ at 3.3V - enables multi-year battery life in always-on wearable sensors |
| Reset Timeout Period | 300ms nominal - ensures sufficient hold time for slow-ramping LDOs or DC-DC converters |
| Minimum Monitored Voltage | 0.6V - supports supervision of modern sub-1V FPGA/microcontroller core supplies |
| Operating Temperature | -40°C to +125°C - qualified for automotive cabin and industrial edge environments |
| Supply Voltage Range | VCC = 1.7V to 5.5V - allows flexible biasing from I/O rails independent of monitored VIN |
| Reset Output Type | Active-low open-drain - enables wired-OR reset bus and compatibility with 1.2V–5V logic families |
Pinout & Package
MAX16162NDK300+ is housed in a 4-bump Wafer-Level Package (WLP), outline 21-100478, measuring 1.06mm × 0.73mm with 0.4mm bump pitch. This ultra-compact, bottom-terminal package targets space-constrained portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low open-drain reset output | Must be pulled up externally; asserts low during fault and remains low for full 300ms after VIN recovery |
| VCC | IC supply voltage input | Provides operating power only; not monitored - enables biasing from stable I/O rail while supervising core rail |
| VIN | Monitored voltage input | Input to internal comparator; threshold set to 3.00V; supports 0.6V–4.85V range |
| GND | Ground reference | Return path for all internal circuits and RST sink current; requires low-inductance connection to system ground plane |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar supply supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16162KEK310+T | Same function and specs, but in 5-pin SOT23 package with NC pin; 310ms timeout (vs. 300ms) | Requires larger PCB area and different layout; suited for prototyping or where hand-soldering is preferred | Select for ease of assembly or when 310ms timeout better matches system timing margin |
| TPS389001DSER | TI part with 3.0V threshold, 200ms timeout, 350nA IQ, and integrated pullup - no external RPU needed | Lacks 0.6V–4.85V VIN flexibility; only monitors VDD (not separate VIN); lower IQ but fixed 200ms timeout | Select when minimizing external components is priority and 200ms timeout suffices for target regulator ramp time |
Compared with MAX16162NDK300+, the MAX16162KEK310+T offers identical supervision logic in a through-hole-friendly package but trades 10ms timeout precision and 0.33mm² footprint for solderability. The TPS389001DSER reduces BOM count via integrated pullup but sacrifices VIN/VCC separation and sub-1V monitoring capability - limiting use in advanced multi-rail systems.

FAQ
What is the exact reset threshold voltage of the MAX16162NDK300+?
The MAX16162NDK300+ has a factory-trimmed reset threshold voltage of 3.00V, with ±1.5% accuracy over the full -40°C to +125°C temperature range. This value is fixed by the "300" suffix in the part number and corresponds to the 3.00V option in Table 3 of the datasheet. The threshold applies to the VIN pin, not VCC.
Does the MAX16162NDK300+ have a manual reset (MR) input?
No, the MAX16162NDK300+ does not include a manual reset input. It is a variant of the MAX16162 family, which omits MR functionality to simplify design and reduce pin count. Only MAX16161 variants (e.g., MAX16161NDK300+) feature MR. The MAX16162NDK300+ relies solely on VIN monitoring for reset assertion.
What package type is used for the MAX16162NDK300+?
The MAX16162NDK300+ is supplied in a 4-bump Wafer-Level Package (WLP) with outline number 21-100478, measuring 1.06mm × 0.73mm and featuring a 0.4mm bump pitch. This RoHS-compliant, lead(Pb)-free package is optimized for minimal footprint in ultra-compact portable electronics.
Can the MAX16162NDK300+ monitor a 0.8V supply rail?
Yes, the MAX16162NDK300+ can monitor supply rails as low as 0.6V on its VIN pin. With a 3.00V threshold, it is intended for rails ≥3.0V, but the device's VIN input range (0.6V–4.85V) and internal architecture support accurate supervision of any rail within that span - including 0.8V, provided the threshold is selected accordingly (e.g., MAX16162NDK080+).
What is the guaranteed reset timeout period for the MAX16162NDK300+?
The MAX16162NDK300+ provides a nominal reset timeout period of 300ms, with a tolerance of ±25% over temperature and process variation. This fixed delay begins when VIN rises above VTH + VHYS (3.00V + 1% hysteresis) and ensures the reset output remains asserted for the full duration before deassertion - critical for stabilizing downstream regulators.
