Product details
Overview
The MAX9064EBS+T from Analog Devices is a nanoPower single comparator with integrated 0.2V reference, push-pull output, and 4-bump UCSP (1mm × 1mm) package. It operates from 1.0V to 5.5V supply, draws ≤700nA quiescent current, and delivers 15µs propagation delay - ideal for ultra-low-power battery monitoring in portable medical devices and wearables.
For engineers reviewing the MAX9064EBS+T datasheet, MAX9064EBS+T pinout, MAX9064EBS+T application, or MAX9064EBS+T equivalent, key selection criteria include its internal 0.2V reference accuracy (±12mV hysteresis), push-pull output eliminating external pull-up, operation down to 1V supply, and guaranteed -40°C to +85°C performance in space-constrained designs.
Technical Context
The MAX9064EBS+T implements a noninverting-input comparator architecture with an on-chip temperature-compensated 0.2V reference. Its input stage supports rail-to-rail input voltage range (-0.3V to +5.5V) independent of VCC, enabling direct sensing of signals exceeding supply voltage - critical for battery voltage detection across discharge curves.
It features a true push-pull output capable of sourcing up to 0.75mA at VCC = 3.3V (VOH ≥ VCC − 0.13V) and sinking up to 1.2mA (VOL ≤ 0.50V), eliminating external pull-up components. Power-up time is 2–3ms, and input shutdown leakage remains <0.1nA when VCC = 0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0V to 5.5V - enables direct interface with single-cell alkaline (0.9V min) or Li-ion systems without level-shifting. |
| Quiescent Supply Current | ≤700nA (max) - extends battery life in always-on sensor nodes and wearable health monitors. |
| Internal Reference Voltage | 0.2V ±12mV hysteresis - provides stable low-threshold detection for battery end-of-life or brown-out signaling. |
| Propagation Delay | 15µs (typ) at ±100mV overdrive - sufficient for slow-varying battery voltage monitoring and power-good assertion. |
| Input Voltage Range | -0.3V to +5.5V - allows input signals to exceed VCC, supporting direct connection to unregulated battery rails. |
| Output Type | Push-pull - drives logic inputs directly without external pull-up, reducing BOM count and PCB area. |
| Operating Temperature | -40°C to +85°C - qualified for industrial and portable medical environments. |
Pinout & Package
MAX9064EBS+T uses a 4-bump UCSP package (1.0mm × 1.0mm × 0.6mm), with bumps on the bottom surface. The package footprint matches two 0402 resistors and requires no lead-frame or wire bonds - optimized for ultra-dense portable PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | OUT | Push-pull output - actively drives high/low; compatible with 1.0V–5.5V logic interfaces without external components. |
| A2 | IN | Noninverting input - accepts analog signals from -0.3V to +5.5V regardless of VCC; high-impedance (>1GΩ) when powered down. |
| B1 | VCC | Power-supply input - bypass with 0.1µF capacitor to GND; powers internal reference and comparator core. |
| B2 | GND | Ground reference - common return for VCC, IN, and OUT; must be low-impedance for RF immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small 4-bump UCSP | 1.0mm × 1.0mm footprint - fits within tight spaces where even SOT23 is prohibitive, e.g., hearing aids and smart patches. |
| Integrated 0.2V reference | ±12mV hysteresis, 6µV/°C tempco - eliminates external reference IC or resistor divider, reducing component count and layout sensitivity. |
| Push-pull output | No external pull-up required - simplifies interface to microcontroller GPIOs and reduces standby current in open-drain alternatives. |
| Rail-to-rail input capability | Accepts inputs beyond VCC (up to +5.5V) - enables direct battery voltage monitoring without attenuation or clamping diodes. |
| Power-down input immunity | Input impedance remains high when VCC = 0V - prevents signal injection into powered-down systems, enhancing system-level safety. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9064EUK+ | Same electrical specs, but in 5-pin SOT23 package (2.9mm × 1.6mm vs. UCSP's 1.0mm × 1.0mm). | Preferred where hand-soldering, test probing, or thermal dissipation >238mW is required. | Select MAX9064EUK+ when board assembly favors larger packages or reworkability is prioritized over miniaturization. |
| TLV3691IDCKR | 0.3V internal reference, 600nA max ICC, open-drain output - requires external pull-up and lacks push-pull drive. | Suitable for cost-sensitive designs where output flexibility (e.g., wired-OR) is needed, not direct logic drive. | Choose TLV3691IDCKR only if open-drain topology aligns with system bus architecture and space constraints allow larger 1.0mm × 1.25mm SC70. |
Compared with MAX9064EUK+, the MAX9064EBS+T saves >75% PCB area and enables higher-density layouts; compared with TLV3691IDCKR, it delivers deterministic logic levels without pull-up, reduces BOM count, and offers tighter reference tolerance (±12mV vs. ±25mV typical).

FAQ
What is the function of the internal 0.2V reference in MAX9064EBS+T?
The internal 0.2V reference in MAX9064EBS+T serves as the fixed comparison threshold for the noninverting input. It is temperature-compensated (6µV/°C), stable across 1.0V–5.5V supply, and enables precise low-voltage detection - such as identifying battery end-of-life at ~0.9V using simple resistor scaling. This eliminates external reference components and associated calibration drift.
Does MAX9064EBS+T require an external pull-up resistor on its output?
No, MAX9064EBS+T does not require an external pull-up resistor because it features a push-pull output stage. Unlike open-drain comparators (e.g., MAX9062), the MAX9064EBS+T actively drives both high and low logic states - sourcing up to 0.75mA and sinking up to 1.2mA - making it directly compatible with standard CMOS/TTL inputs without additional components.
Can MAX9064EBS+T operate with a 0.9V supply voltage?
MAX9064EBS+T is specified to operate down to 1.0V supply voltage per datasheet Absolute Maximum Ratings and Electrical Characteristics tables. While some units may function at 0.9V, it is not guaranteed - the device's VOL, VOH, propagation delay, and reference accuracy are only characterized and warranted from VCC = 1.0V to 5.5V.
What is the maximum input voltage allowed on the IN pin of MAX9064EBS+T?
The IN pin of MAX9064EBS+T supports an absolute maximum input voltage of -0.3V to +6.0V (per Absolute Maximum Ratings), and functional operation is guaranteed from -0.3V to +5.5V independent of VCC. This rail-to-rail input capability allows direct connection to unregulated battery rails or signals exceeding the supply voltage - a key advantage over traditional comparators with ESD-clamp-limited inputs.
How does the UCSP package of MAX9064EBS+T impact PCB layout and assembly?
The 4-bump UCSP package of MAX9064EBS+T (1.0mm × 1.0mm, 0.6mm height) requires precise stencil design and controlled reflow profiling due to its bump-on-bottom construction. It eliminates leads and wire bonds, reducing parasitic inductance - beneficial for RF immunity - but demands X-ray inspection for void detection. Footprint matches two 0402 passives, enabling placement in ultra-dense areas inaccessible to SOT23.
