Product details
Overview
The MAX40001ANT22+T from Maxim Integrated is a nanoPower, open-drain comparator with integrated 2.22V precision voltage reference, designed for ultra-low-power level detection in space-constrained portable electronics. It operates from 1.7V to 5.5V, draws only 0.9μA supply current, features 2.5mV internal hysteresis, and is fully specified over –40°C to +125°C for automotive-grade reliability.
For engineers reviewing the MAX40001ANT22+T datasheet, MAX40001ANT22+T pinout, MAX40001ANT22+T application, or MAX40001ANT22+T equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use-value analysis, and validated alternative options - all grounded in Maxim's official 19-8610 Rev 6 specification.
Technical Context
The MAX40001ANT22+T integrates a factory-trimmed bandgap reference (±1% initial accuracy, <2.5% over –40°C to +125°C) with a rail-to-rail input stage supporting –0.2V to VDD + 0.2V common-mode range and an open-drain output capable of sinking up to 2mA while tolerating pullup voltages up to 5.5V. Its break-before-make output architecture minimizes supply-current surges during switching.
Internal 2.5mV hysteresis eliminates oscillation near threshold transitions, and the device maintains stable reference output into capacitive loads ≤100pF. RF immunity is enhanced via on-chip filtering - critical for noisy portable environments like cell phones and wearables.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.7V to 5.5V - supports direct operation from 1.8V/2.5V/3V/5V rails without regulation. |
| Quiescent Current | 0.9μA typical - enables multi-year battery life in always-on monitoring circuits. |
| Reference Voltage | 2.22V ±1% at +25°C, <2.5% over –40°C to +125°C - eliminates need for external precision reference. |
| Propagation Delay | 14μs L→H (100kΩ pullup), 5.2μs H→L - balances speed and power for low-frequency threshold detection. |
| Input Common-Mode Range | –0.2V to VDD + 0.2V - allows detection of signals slightly beyond supply rails (e.g., battery overvoltage). |
| Output Type | Open-drain - enables wired-OR logic, level translation (e.g., 5V-to-3V), and shared-pullup fault-detection networks. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial edge-sensing applications. |
Pinout & Package
MAX40001ANT22+T uses a 6-bump wafer-level package (WLP) with 1.11mm × 0.76mm footprint and 0.35mm pitch (Package Code: N60D1+1). The WLP is bottom-terminal; bump layout matches standard SOT23 pinout functionally but requires micro-scale PCB land pattern per Application Note 1891.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B1 | Inverting Input (IM) | Accepts reference or fixed threshold voltage; high-impedance node (±1nA bias current). |
| B2 | Reference Output (REF) | 2.22V precision voltage source; stable into 100pF; bypass with 0.1μF capacitor if noise-sensitive. |
| B3 | Ground (GND) | Primary return path for reference, comparator, and output sink current. |
| A1 | Noninverting Input (IP) | Monitors signal (e.g., battery voltage, sensor output); supports –0.2V to VDD + 0.2V range. |
| A2 | Supply (VDD) | 1.7V–5.5V power input; bypass with 0.1μF capacitor close to bump for noise rejection. |
| A3 | Open-Drain Output (OUT) | Sinks up to 2mA; requires external pullup (e.g., 100kΩ to 3.3V/5V); enables level translation and fault-wire ORing. |
Key Features
| Feature | Design Value |
|---|---|
| NanoPower Operation | 0.9μA supply current enables decade-scale battery life in coin-cell-powered wearables and IoT sensors. |
| Integrated 2.22V Reference | ±1% initial accuracy and <2.5% tempco over –40°C to +125°C replaces discrete reference + resistor divider, saving ≥3 mm² PCB area. |
| Open-Drain Output Architecture | Supports mixed-voltage systems: e.g., 5V VDD with 3V pullup enables safe 5V→3V logic translation without level-shifters. |
| 2.5mV Internal Hysteresis | Prevents chatter on slow-moving inputs (e.g., thermistor ramps, battery discharge curves) without external components. |
| Rail-to-Rail Input Stage | –0.2V to VDD + 0.2V common-mode range allows direct monitoring of battery terminals or unbuffered sensor outputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV4041DBVR | Fixed 1.2V reference; 1.8V–5.5V supply; 1.8μA IDD; SOT23-6 only | Lacks automotive temp range (–40°C to +125°C); lower reference voltage limits high-threshold detection | Select TLV4041DBVR only for cost-sensitive consumer apps where 1.2V threshold suffices and extended temp not required. |
| MAX40000ANT22+T | Same 2.22V reference, WLP/SOT23 options, and temp range - but push-pull (not open-drain) output | Cannot perform wired-OR or level translation; requires dedicated output load path | Choose MAX40000ANT22+T when driving LEDs or logic gates directly without pullup; avoid if shared-bus fault detection needed. |
Compared with TLV4041DBVR, MAX40001ANT22+T offers superior temperature stability and lower power for automotive-grade sensing; compared with MAX40000ANT22+T, its open-drain output enables flexible interface topologies - making it the sole choice for multi-comparator fault-wire schemes or mixed-voltage logic translation.
