Product details
Overview
The MAX9062EBS+TG45 from Analog Devices is a nanoPower single comparator with integrated 0.2V reference, noninverting input, and open-drain output, housed in a 4-bump UCSP package (1mm × 1mm × 0.6mm). It operates from 1.0V to 5.5V supply, draws ≤700nA quiescent current, supports −40°C to +85°C, and delivers 15µs propagation delay - ideal for ultra-low-power voltage monitoring in space-constrained battery-powered systems.
For engineers reviewing the MAX9062EBS+TG45 datasheet, MAX9062EBS+TG45 pinout, MAX9062EBS+TG45 application, or MAX9062EBS+TG45 equivalent, key selection criteria include its internal 0.2V reference accuracy (±12mV hysteresis), rail-to-rail input range (−0.3V to +5.5V), ultra-low ICC at 1V supply (0.4µA typ), UCSP footprint compatibility with 0402 resistors, and power-down input high-impedance behavior when VCC = 0V.
Technical Context
The MAX9062EBS+TG45 implements a BiCMOS input stage enabling input voltages up to 6V beyond GND regardless of VCC level, with no ESD diode clamping - allowing safe interfacing to signals exceeding supply rails. Its internal temperature-compensated 0.2V reference is trimmed to ±12mV over temperature and exhibits 6µV/°C tempco.
This device uses an open-drain output stage requiring external pull-up, supporting logic-level translation across supply domains. Its propagation delay remains stable across input overdrive (10–250mV) and temperature (−40°C to +85°C), with typical tPD = 15µs at 100mV overdrive and CL = 10pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0V to 5.5V - enables direct operation from single AA/AAA cell (down to 0.9V) or low-voltage microcontroller rails. |
| Quiescent Supply Current | ≤700nA max - extends battery life in always-on sensing nodes; 0.4µA typ at VCC = 1.0V. |
| Input Voltage Range | −0.3V to +5.5V independent of VCC - permits monitoring of signals beyond supply rails without level-shifting. |
| Internal Reference Voltage | 0.2V ±12mV over −40°C to +85°C - fixed threshold for low-voltage brown-out detection or wake-up triggers. |
| Propagation Delay | 15µs typical at ±100mV overdrive - balances speed and nanoPower consumption for event-driven wake-up circuits. |
| Input Offset Voltage | 1.3mV to 9mV - defines minimum detectable voltage difference above 0.2V reference. |
| Hysteresis | ±12mV - suppresses noise-induced false triggering on slow-moving or noisy input signals. |
Pinout & Package
MAX9062EBS+TG45 uses a 4-bump UCSP (Ultra Compact Silicon Package) with 0.5mm pitch, 1mm × 1mm footprint, and 0.6mm height. The package features bumps on the bottom surface; top marking is "AFZ". G45 denotes protective die coating; T indicates tape-and-reel packaging.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | OUT | Open-drain comparator output - requires external pull-up; sinks current when VIN > 0.2V; floats when VIN < 0.2V. |
| A2 | IN | Noninverting input - accepts signals from −0.3V to +5.5V; maintains high impedance even with VCC = 0V. |
| B1 | VCC | Positive supply terminal - powers internal circuitry and reference; bypass with 0.1µF capacitor to GND. |
| B2 | GND | Ground reference - common return path for supply, input, and output circuits. |
Key Features
| Feature | Design Value |
|---|---|
| 4-bump UCSP footprint | 1mm × 1mm area - occupies same PCB area as two 0402 passives, enabling placement in tight RF or sensor zones. |
| Rail-to-rail input capability | −0.3V to +5.5V input range independent of VCC - eliminates need for external attenuators or level shifters. |
| Power-down input isolation | Input remains high-impedance when VCC = 0V - prevents back-driving of signal sources during system sleep modes. |
| On-chip RF filtering | Integrated input-stage filtering - rejects GSM/Bluetooth-band interference without external ferrites or RC networks. |
| Internal 0.2V reference | Trimmed, temperature-compensated reference - provides stable low-threshold detection without external precision references. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9062EUK+ | Same electrical specs, but in 5-pin SOT23 package (3.05mm × 1.65mm) - larger footprint, higher thermal mass, easier hand-soldering. | Suitable for prototyping, lower-volume production, or designs where UCSP reflow capability is unavailable. | Select MAX9062EUK+ when board assembly lacks fine-pitch UCSP reflow capability or when thermal derating above 70°C is required (312mW vs. 238mW). |
| TLV7011DBVR | Lower supply current (350nA max), but no internal reference; requires external reference or resistor divider; 6-pin SOT23 package. | Used where adjustable thresholds are needed or where higher precision (1.5mV VOS) outweighs added component count. | Choose TLV7011DBVR only if design requires user-defined thresholds or tighter offset spec; adds BOM complexity and board area vs. MAX9062EBS+TG45's integrated 0.2V reference. |
Compared with MAX9062EUK+, the MAX9062EBS+TG45 saves >80% PCB area and enables higher-density layouts; compared with TLV7011DBVR, it eliminates external reference components and simplifies layout, though with slightly higher ICC and fixed threshold.

FAQ
What is the function of the internal 0.2V reference in MAX9062EBS+TG45?
The internal 0.2V reference in MAX9062EBS+TG45 serves as a fixed, temperature-compensated threshold for the comparator's decision point. It eliminates the need for external reference components, enabling compact, low-BOM-count designs. This reference is trimmed to ±12mV over −40°C to +85°C and exhibits 6µV/°C tempco, making MAX9062EBS+TG45 suitable for precision low-voltage detection such as battery UVLO or sensor wake-up triggers.
Can MAX9062EBS+TG45 operate with supply voltage below 1.0V?
No, MAX9062EBS+TG45 is specified to operate down to 1.0V supply voltage per its Absolute Maximum Ratings and Electrical Characteristics tables. Operation below 1.0V is not guaranteed - parameters like propagation delay, output low voltage, and reference accuracy degrade outside the 1.0V–5.5V range. For sub-1V applications, consider alternative comparators explicitly rated for 0.9V operation, such as the MAX9060 series with external reference.
Does MAX9062EBS+TG45 support rail-to-rail input when VCC = 1.0V?
Yes, MAX9062EBS+TG45 maintains its full −0.3V to +5.5V input voltage range independent of VCC level - including at VCC = 1.0V. This is enabled by its innovative BiCMOS input architecture without ESD diode clamping to VCC. As a result, inputs can safely exceed VCC by several volts (within Absolute Maximum Ratings), allowing direct interface to higher-voltage sensors or legacy signals without level-shifting circuitry.
What is the purpose of the G45 suffix in MAX9062EBS+TG45?
The G45 suffix in MAX9062EBS+TG45 indicates protective die coating - a conformal layer applied to the silicon die to enhance moisture resistance and mechanical robustness in harsh or high-humidity environments. This coating improves reliability during reflow soldering and long-term field operation, particularly in consumer electronics and portable medical devices exposed to variable ambient conditions.
How does the open-drain output of MAX9062EBS+TG45 interface with a 3.3V microcontroller I/O pin?
The open-drain output of MAX9062EBS+TG45 interfaces with a 3.3V microcontroller I/O pin using an external pull-up resistor (e.g., 10kΩ) tied to the MCU's 3.3V rail. When the comparator input exceeds 0.2V, the output pulls low (VOL ≤ 0.2V at 50µA sink); when input is below 0.2V, the output floats and the pull-up drives the node to 3.3V. This configuration ensures logic-level compatibility and avoids bus contention, even if the MAX9062EBS+TG45 itself runs at 1.0V.
