Product details
Overview
MAX16161NDK300+T from Analog Devices is a nanoPower single-channel supply supervisor IC designed for ultra-low-voltage, battery-powered systems. It monitors VCC (1.7V–5.5V), asserts an active-low open-drain reset output when voltage falls below 3.00V threshold, guarantees glitch-free power-up/down by holding RST asserted down to 0V VCC, and features 825nA typical quiescent current - enabling reliable reset control in e-readers, wearables, and low-voltage microcontroller cores.
For engineers reviewing the MAX16161NDK300+T datasheet, MAX16161NDK300+T pinout, MAX16161NDK300+T application, or MAX16161NDK300+T equivalent, this page delivers verified technical context, exact pin functions for the 4-bump WLP package, confirmed reset timeout (1000ms typ), factory-set 3.00V threshold, and validated alternatives for low-power supervisory design.
Technical Context
The MAX16161NDK300+T implements a precision bandgap-based voltage monitor with 1% threshold accuracy and 1% hysteresis, coupled to a glitch-immune reset timer that only deasserts RST after VCC rises above VTH + VHYS and the full 1000ms timeout elapses. Its MR input supports both active-low and active-high triggering with 20ms debounce, ensuring noise immunity during manual reset events.
Unlike conventional supervisors, it maintains RST in a valid logic-low state even at 0V VCC via internal current-sinking capability - eliminating undefined regions during slow power ramps. The device operates across –40°C to +125°C and uses a 0.1μF ceramic bypass capacitor on VCC to ensure transient immunity in portable applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.00V ±1.5% - factory-trimmed for precise brownout detection in 3.3V I/O domains. |
| Quiescent Current | 825nA typ at 3.3V - extends battery life in always-on wearable sensors and e-reader standby modes. |
| Reset Timeout Period | 1000ms nominal (SUFFIX G) - provides sufficient delay for stable LDO/DC-DC startup before MCU release. |
| Operating Voltage Range | 1.7V to 5.5V - supports direct monitoring of 1.8V, 2.5V, 3.3V, and 5V rails without external level shifting. |
| Reset Output Type | Active-low open-drain - enables wired-OR reset bus configuration and flexible pullup voltage selection (≤3.6V). |
| Temperature Range | –40°C to +125°C - qualified for automotive infotainment modules and industrial edge controllers. |
| Threshold Hysteresis | 1% of VTH - prevents chatter during slow-rising supply edges near trip point. |
Pinout & Package
MAX16161NDK300+T is housed in a 1.06mm × 0.73mm, 4-bump Wafer-Level Package (WLP) with bottom-side solder bumps. This ultra-compact package enables high-density PCB layouts in space-constrained portable devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low open-drain reset output | Sinks current to hold downstream MCU in reset until VCC stabilizes above 3.00V + hysteresis and 1000ms timeout expires. |
| VCC | Supply and monitored voltage input | Powers internal circuitry and serves as the reference for 3.00V threshold detection; requires 0.1μF ceramic bypass to GND. |
| MR | Manual reset input | Accepts active-low or active-high logic signal (configurable per ordering suffix K/L); includes 20ms internal debounce. |
| GND | Ground reference | Provides return path for internal bias currents and reset sink current; must be connected to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-free power-up/-down | RST remains asserted down to 0V VCC - eliminates false releases during slow ramp-up or brownout recovery. |
| Ultra-low quiescent current | 825nA typical - reduces standby power draw in battery-backed systems by >90% vs. standard supervisors. |
| Configurable manual reset | Supports both active-low (K) and active-high (L) MR polarity - simplifies integration with diverse host logic interfaces. |
| Factory-trimmed threshold | 3.00V ±1.5% - removes need for external resistor dividers and improves system-level voltage margin accuracy. |
| Robust reset timing | 1000ms timeout with ±25% accuracy over –40°C to +125°C - ensures deterministic sequencing across temperature extremes. |
Applications
| Low-Voltage Microcontroller Supervision | e-Reader Power Sequencing |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar supply supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16162NDK300+T | No MR input; separate VIN pin enables 0.6V–4.85V monitoring range; identical 3.00V threshold and 1000ms timeout. | Used where manual reset is unnecessary but ultra-low-voltage core monitoring (e.g., 0.8V FPGA core) is required. | Select MAX16162NDK300+T if MR functionality is unused and VIN/VCC separation improves system flexibility. |
| TPS3808G30DBVR | Higher 1.2μA ICC; fixed 3.0V threshold; 200ms default timeout (adjustable via capacitor); SOT23-5 package. | Targets cost-sensitive industrial designs where 200ms timeout suffices and WLP size is not critical. | Choose TPS3808G30DBVR only if board area permits SOT23-5 and higher quiescent current is acceptable. |
Compared with MAX16161NDK300+T, MAX16162NDK300+T removes MR but adds VIN monitoring down to 0.6V - ideal for core-rail supervision - while TPS3808G30DBVR trades nanoPower efficiency and WLP footprint for lower unit cost and adjustable timeout, requiring layout revision.

FAQ
What is the exact reset threshold voltage of MAX16161NDK300+T?
The MAX16161NDK300+T has a factory-trimmed reset threshold of 3.00V with ±1.5% accuracy over –40°C to +125°C. This value is fixed and non-adjustable, corresponding to the "300" suffix in the part number. It is specified for VCC falling conditions and includes 1% hysteresis to prevent oscillation near the trip point. The threshold applies directly to the VCC pin, which serves as both supply and monitored rail.
Does MAX16161NDK300+T support manual reset, and how is its polarity configured?
Yes, MAX16161NDK300+T includes a manual reset (MR) input supporting both active-low and active-high triggering. Polarity is determined by the ordering suffix: "K" denotes active-low MR (default), while "L" denotes active-high MR. The device incorporates 20ms internal debounce circuitry to reject contact bounce from pushbutton switches. MR assertion forces RST low regardless of VCC level, and deassertion initiates the 1000ms timeout before RST releases.
What package type and dimensions does MAX16161NDK300+T use?
MAX16161NDK300+T is supplied in a 4-bump Wafer-Level Package (WLP) with outline number 21-100478 and land pattern referenced in Analog Devices Application Note 1891. Its physical dimensions are 1.06mm × 0.73mm, with bump pitch of 0.4mm. This ultra-compact package is optimized for high-density portable PCBs and requires compatible reflow profiles per JEDEC J-STD-020.
How does MAX16161NDK300+T achieve glitch-free power-up behavior?
MAX16161NDK300+T achieves glitch-free power-up by guaranteeing the RST output remains asserted - even when VCC is 0V - through an internal current-sinking structure that holds RST low independent of supply voltage. Unlike conventional supervisors whose RST floats or tracks VCC at low voltages, MAX16161NDK300+T only deasserts RST after VCC rises above 3.00V + hysteresis and the full 1000ms timeout period elapses. This eliminates undefined states during slow ramps.
What is the recommended pullup resistor value for the RST output of MAX16161NDK300+T?
A 10kΩ pullup resistor to a logic-compatible voltage (≤3.6V when VCC > 2V, or ≤1.8×VCC when VCC ≤ 2V) is recommended for the RST output of MAX16161NDK300+T. This value ensures VOL remains below 0.4V under worst-case sink conditions while limiting current to <1μA during reset assertion. Larger values (e.g., 100kΩ) may be used to further reduce leakage but require verification against downstream input thresholds and noise immunity requirements.
