Product details
Overview
The MAX9062EBS+T 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 (1mm × 1mm × 0.6mm). It operates from 1.0V to 5.5V supply, draws ≤700nA quiescent current, and delivers 15µs propagation delay across –40°C to +85°C - ideal for low-voltage battery monitoring in portable medical devices.
For engineers reviewing the MAX9062EBS+T datasheet, MAX9062EBS+T pinout, MAX9062EBS+T application, or MAX9062EBS+T equivalent, this page provides verified technical context, package-validated pin functions, real-world use scenarios, and two confirmed alternative comparators with documented functional and interface differences.
Technical Context
The MAX9062EBS+T implements a BiCMOS input stage enabling rail-to-rail input voltage range (–0.3V to +5.5V) independent of VCC, and maintains high-impedance inputs even when powered down (VCC = 0V). Its internal 0.2V reference is temperature-compensated (6µV/°C tempco) and stable over supply voltages from 1.0V to 5.5V.
This device uses an open-drain output requiring external pull-up, supports hysteresis-enabled noise immunity, and features on-chip RF filtering. It is not pin-compatible with push-pull-output variants like MAX9064, and its noninverting input topology differs functionally from inverting-input MAX9063.
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 at full discharge) or low-voltage digital rails. |
| Quiescent Supply Current | ≤700nA (max) - extends battery life in always-on sensing nodes beyond 10 years with typical coin-cell capacity. |
| Input Voltage Range | –0.3V to +5.5V - allows input signals to exceed VCC without clamping diodes, supporting flexible signal routing in mixed-supply systems. |
| Internal Reference Voltage | 0.2V ±15mV (–40°C to +85°C) - fixed threshold for ultra-low-voltage detection (e.g., brown-out, battery depletion) without external components. |
| Propagation Delay | 15µs (typ, ±100mV overdrive) - sufficient for slow-changing sensor outputs (e.g., thermistor, photodiode) while minimizing dynamic power. |
| Input Offset Voltage | 1.3mV (min), 6mV (typ), 9mV (max) - defines minimum detectable differential at the 0.2V reference, critical for precision thresholding. |
| Hysteresis | ±12mV - suppresses false triggering from EMI or noisy analog inputs without requiring external feedback resistors. |
Pinout & Package
Package: 4-bump UCSP (B4+1), 1.0mm × 1.0mm × 0.6mm footprint, bottom-side bumps, RoHS-compliant (+T suffix denotes tape-and-reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | OUT | Open-drain output - requires external pull-up resistor; sinks current when VIN > 0.2V; floats high otherwise. |
| A2 | IN | Noninverting input - compares applied voltage against internal 0.2V reference; accepts –0.3V to +5.5V regardless of VCC. |
| B1 | VCC | Power-supply input - supplies operating current and powers internal reference; bypass with 0.1µF capacitor to GND. |
| B2 | GND | Analog ground reference - common return path for VCC, IN, and OUT; must be low-impedance for stable reference accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small 4-bump UCSP | 1mm × 1mm footprint - occupies same board area as two 0402 resistors, enabling placement in space-constrained wearables and hearing aids. |
| Integrated 0.2V reference | Stable over 1.0V–5.5V VCC and –40°C to +85°C - eliminates external reference IC or resistor divider, reducing BOM count and layout complexity. |
| Rail-to-rail input capability | Inputs functional at –0.3V to +5.5V independent of VCC - supports direct connection to sensors or signals referenced to different supplies. |
| Power-down input impedance | High-Z inputs at VCC = 0V - prevents back-driving of sensor circuits during system sleep, preserving signal integrity and power savings. |
| On-chip RF filtering | Immunity to conducted and radiated RF noise - avoids external RC filters on IN line, simplifying EMC design for FCC/CE-certified portable devices. |

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 × 1.75mm) - 3× larger footprint, higher thermal resistance (312mW max vs. 238mW). | Suitable where hand-soldering or prototyping ease outweighs board space constraints; not interchangeable without PCB redesign. | Select MAX9062EUK+ for evaluation or low-volume assembly; choose MAX9062EBS+T for production miniaturization. |
| TLV3691IDCKR | 0.3V internal reference, 350nA max ICC, SOT23-5 package - lacks UCSP option, no guaranteed –0.3V input capability, and no specified RF immunity. | Acceptable for cost-sensitive, non-medical consumer toys where 0.3V threshold suffices and board space is less constrained. | Use TLV3691IDCKR only if 0.2V threshold is not required and UCSP size is unnecessary; verify input range compatibility per design. |
Compared with MAX9062EUK+, the MAX9062EBS+T saves >75% board area and improves thermal performance in sealed enclosures; compared with TLV3691IDCKR, it offers tighter reference accuracy, wider input range, and proven RF robustness - critical for certified medical and industrial portable designs.

FAQ
What is the exact function of the MAX9062EBS+T in a circuit?
The MAX9062EBS+T functions as a noninverting comparator with an integrated 0.2V reference voltage and open-drain output. It compares the voltage at its IN pin to the internal 0.2V threshold and pulls its OUT pin low when IN exceeds 0.2V. This makes MAX9062EBS+T ideal for fixed-threshold detection tasks such as battery brown-out monitoring or sensor trip-point signaling without external reference components.
Does the MAX9062EBS+T require an external pull-up resistor?
Yes, the MAX9062EBS+T has an open-drain output and requires an external pull-up resistor to define the high-state voltage level. The value depends on speed and drive strength needs - typically 10kΩ to 3.3V or 5.5V - and must be placed close to the OUT pin. Without this resistor, the output cannot assert a logic high, rendering MAX9062EBS+T nonfunctional in most digital interface applications.
Can the MAX9062EBS+T operate with a supply voltage lower than 1.0V?
No, the MAX9062EBS+T is specified to operate only from 1.0V to 5.5V supply voltage. Below 1.0V, parameters including reference accuracy, propagation delay, and output drive are not guaranteed. While some units may appear functional at 0.9V, Analog Devices does not characterize or warrant performance below the 1.0V minimum - thus MAX9062EBS+T must be used within its rated VCC range for reliable operation.
Is the MAX9062EBS+T pin-compatible with other devices in the MAX9060–MAX9064 family?
No, the MAX9062EBS+T is not pin-compatible with MAX9060/MAX9061 (which use REF instead of VCC) or MAX9064 (which has push-pull output and different pin mapping). Even within UCSP variants, the bump assignments differ: MAX9062EBS+T uses VCC on B1, whereas MAX9060EBS+G45 uses REF on B1. Therefore, substituting MAX9062EBS+T for any other family member requires PCB redesign and firmware validation.
How does the MAX9062EBS+T handle input signals exceeding the supply voltage?
The MAX9062EBS+T supports input voltages from –0.3V to +5.5V independent of VCC, meaning its IN pin can safely accept signals up to 5.5V even when powered from 1.0V. This is enabled by its specialized BiCMOS input stage without ESD diode clamps to VCC. As a result, MAX9062EBS+T can interface directly with higher-voltage sensors or legacy analog signals without level-shifting circuitry - a key advantage over conventional comparators.
