Product details
Overview
The MAX9063EBS+TG45 from Analog Devices is a nanoPower single comparator with integrated 0.2V reference, inverting input configuration, open-drain output, and ultra-small 4-bump UCSP (1mm × 1mm) package. It operates from 1.0V to 5.5V supply, draws ≤700nA quiescent current, and delivers 15µs propagation delay over –40°C to +85°C - ideal for battery-critical signal threshold detection in portable medical sensors.
For engineers reviewing the MAX9063EBS+TG45 datasheet, MAX9063EBS+TG45 pinout, MAX9063EBS+TG45 application, or MAX9063EBS+TG45 equivalent, key selection criteria include its inverting-input topology, internal 0.2V reference accuracy (±12mV hysteresis), G45 protective die coating, UCSP footprint compatibility with 0402 resistor layouts, and operation down to 1V supply for single-cell AA/AAA systems.
Technical Context
The MAX9063EBS+TG45 implements an inverting-input comparator architecture with internal 0.2V reference voltage and open-drain output stage requiring external pull-up. Its input stage supports rail-to-rail input voltage range (–0.3V to +5.5V) independent of VCC and maintains high impedance even when powered down (VCC = 0V).
It features on-chip filtering for RF immunity, internal hysteresis (±0.9mV typical over temperature), and power-up time of 2–3ms. The device uses BiCMOS process and is specified across –40°C to +85°C with junction temperature limit of +150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0V to 5.5V - enables direct use with single alkaline or lithium coin cells without regulation. |
| Quiescent Supply Current | ≤700nA max - extends battery life in always-on sensor wake-up circuits beyond 10 years. |
| Input Offset Voltage | 1.3mV (typ), 6mV (max) at +25°C - ensures precise 0.2V threshold detection with minimal trip-point error. |
| Propagation Delay | 15µs (typ) at ±100mV overdrive - supports reliable low-frequency event detection (e.g., button press, lid open). |
| Input Voltage Range | –0.3V to +5.5V - allows input signals to exceed VCC, enabling direct connection to unregulated or higher-voltage analog sources. |
| Hysteresis | ±0.9mV (typ) over –40°C to +85°C - provides noise margin against EMI-induced false triggering in handheld environments. |
| Reference Voltage | 0.2V ±12mV (hysteresis), 6µV/°C tempco - stable low-threshold reference for ultra-low-voltage brown-out or battery depletion sensing. |
Pinout & Package
MAX9063EBS+TG45 is housed in a 4-bump UCSP package (1.0mm × 1.0mm × 0.6mm), RoHS-compliant with G45 protective die coating. Bump pitch is 0.5mm; land pattern follows Maxim/Analog Devices outline 21-0789 (B4+1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | OUT | Open-drain output - requires external pull-up; sinks current when VIN > 0.2V (inverting logic behavior). |
| A2 | IN | Inverting input - threshold comparison occurs when input falls below 0.2V reference. |
| B1 | VCC | Power-supply input - bypass to GND with 0.1µF capacitor; powers internal circuitry and reference. |
| B2 | GND | Ground reference - common return for VCC, IN, and OUT; must be low-impedance for stable hysteresis. |
Key Features
| Feature | Design Value |
|---|---|
| 4-bump UCSP footprint | 1mm × 1mm area - fits within space of two 0402 passives, enabling ultra-dense PCB layouts for wearables. |
| Inverting-input + 0.2V reference | Dedicated low-threshold detection - triggers output low when input drops below 0.2V, ideal for battery voltage sag monitoring. |
| 1V minimum supply operation | Functional down to single-cell discharge endpoint (~0.9V) - eliminates need for LDO in energy-harvesting or primary-cell systems. |
| Input high-impedance during power-down | Leakage <0.1nA at VCC = 0V - prevents signal loading or back-powering in multi-rail power-gated subsystems. |
| On-chip RF filtering | Immunity to >100MHz noise - reduces need for external ferrite beads or RC filters in noisy portable RF environments. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9063EUK+ | Same electrical specs, but in 5-pin SOT23 package (3.05mm × 1.65mm) - 3× larger footprint, no G45 coating. | Suitable for prototyping or boards with available space; lacks die protection for harsh environments. | Select for breadboarding or legacy SOT23 layouts where UCSP rework is impractical. |
| TLV3691IDCKR | 0.3V internal reference, 650nA supply current, SC-70-5 package; no G45 rating; input range limited to VSS to VDD. | Requires ≥1.4V supply; cannot accept inputs below GND or above VDD - unsuitable for overvoltage-tolerant designs. | Choose only if 0.3V threshold suffices and board space permits SC-70; verify input voltage compliance per design. |
Compared with MAX9063EUK+, the MAX9063EBS+TG45 saves >85% board area and adds die-level moisture/contamination protection; versus TLV3691IDCKR, it offers lower threshold, wider input range, and guaranteed 1V operation - critical for primary-cell and ruggedized portable systems.

FAQ
What is the function of the G45 suffix in MAX9063EBS+TG45?
The G45 suffix denotes protective die coating applied to the UCSP die surface, enhancing resistance to moisture, ionic contamination, and mechanical abrasion during assembly and field operation. This coating is especially valuable in wearable and portable medical devices exposed to sweat or environmental humidity. The MAX9063EBS+TG45 retains full electrical specifications under G45 protection, and the coating is qualified per JEDEC standards for reliability in extended-temperature applications.
Does MAX9063EBS+TG45 require an external pull-up resistor on the output?
Yes, the MAX9063EBS+TG45 features an open-drain output and requires an external pull-up resistor to establish a valid HIGH logic level. Typical values range from 10kΩ to 100kΩ depending on speed and drive requirements. The pull-up may connect to any compatible voltage rail (e.g., MCU I/O voltage), independent of VCC. This flexibility allows interfacing with mixed-voltage systems - a key capability confirmed in the MAX9063EBS+TG45 datasheet's Typical Operating Circuits section.
Can MAX9063EBS+TG45 operate with input voltages below ground?
Yes, the MAX9063EBS+TG45 supports an input voltage range of –0.3V to +5.5V relative to GND, independent of VCC. This allows direct connection to signals that swing slightly negative - such as AC-coupled sensor outputs or op-amp stages with bipolar supplies - without clamping diodes or level-shifting circuitry. This specification is explicitly guaranteed in the Absolute Maximum Ratings and DC Characteristics tables of the MAX9063EBS+TG45 datasheet.
What is the actual threshold voltage used by MAX9063EBS+TG45?
The MAX9063EBS+TG45 uses an internal precision reference of 0.2V (185mV to 215mV over temperature), configured as the fixed comparison threshold. Because it is an inverting-input comparator, the output goes LOW when the IN pin voltage falls *below* this 0.2V threshold. This behavior is confirmed in Table 1 ("How Devices Behave Under Various Input Voltage Conditions") and the "Detailed Description" section of the MAX9063EBS+TG45 datasheet.
Is MAX9063EBS+TG45 pin-compatible with other MAX906x variants in UCSP?
No - while all MAX906x UCSP variants share the same 4-bump physical layout (A1/A2/B1/B2), their bump functions differ by part number. For MAX9063EBS+TG45, A2 is IN (inverting), B1 is VCC, and A1 is OUT. In contrast, MAX9060EBS+G45 assigns B1 to REF instead of VCC. Therefore, direct PCB substitution without schematic and layout review is not supported. The MAX9063EBS+TG45 pinout is uniquely defined for inverting-comparator operation with internal reference.
