【Product Overview】

The MAX40003ANS02 is a single-channel nano-watt comparator, with its core advantages being exceptionally low power consumption and a remarkably compact package size.

 

The MAX40003ANS02 features a typical quiescent supply current of just 500nA, with a maximum of no more than 1.1μA, significantly extending battery life in portable devices.

 

The MAX40003ANS02 utilises a diminutive 4-bump wafer-level package (WLP) measuring just 0.73mm x 0.73mm, occupying approximately the area of two 0402 resistors. This makes it exceptionally well-suited for applications with constrained PCB space.

 

The MAX40003ANS02 operates from 1.7V to 5.5V supply voltages, with a wide input range of 0.1V to 5.5V independent of the supply voltage. The input remains high impedance even during power-down (VCC or external VREF=0V).

 

The MAX40003ANS02 also offers factory-trimmed reference voltage options (0.2V, 0.5V, 0.9V, 1.222V), eliminating the need for external references and saving both space and cost.

 

【Core Features】

The MAX40003ANS02 is a single-channel comparator integrating multiple advanced features that set it apart from other comparators.

 

Ultimate Energy Efficiency and High Performance

Nano-level Power Consumption: The most striking feature of the MAX40003ANS02 is its typical supply current consumption of just 500nA (maximum 1.1μA), earning it the designation of a ‘nano-power’ device. This exceptionally low power consumption significantly extends battery life in applications requiring continuous monitoring.

Wide Supply Voltage Range: The MAX40003ANS02 supports a supply voltage range from 1.7V to 5.5V. This enables flexible integration into various power systems operating at 1.8V, 2.5V, 3V, and 5V, enhancing design flexibility.

Wide Input Voltage Range: The MAX40003ANS02 features an input voltage range from 0.1V to 5.5V, independent of the supply voltage. Even during power-down conditions (VCC or external VREF = 0V), the input remains in a high-impedance state, enhancing system reliability.

 

Precision Comparison and Rapid Response

Internal Voltage Reference: The MAX40003ANS02 offers factory-trimmed precision reference voltage options, including 0.2V, 0.5V, 0.9V, and 1.222V. This eliminates the need for external references, saving space and cost.

Rapid Response Capability: Despite being an ultra-low-power comparator, the MAX40003ANS02 delivers a typical propagation delay of 9μs, achieving an excellent balance between power consumption and speed.

Integrated Hysteresis: The MAX40003ANS02 incorporates 8mV of built-in hysteresis. This effectively prevents oscillation near input voltage thresholds, enhancing output stability and reducing false triggering.

 

Exceptional Robustness and Immunity

High RF Immunity: The MAX40003ANS02 incorporates internal filtering to deliver high radio-frequency immunity. This is particularly crucial for portable devices operating in complex electromagnetic environments.

Excellent Power Supply Rejection: The MAX40003ANS02 achieves a minimum PSRR (Power Supply Rejection Ratio) of 70dB. This enables effective suppression of power supply noise, ensuring accurate comparison results.

 

 

【Detailed Performance Parameters】

The MAX40003ANS02 demonstrates outstanding electrical performance. Its propagation delay is typically 9μs, offering an excellent balance between speed and power consumption.

 

With a typical hysteresis of 8mV, the MAX40003ANS02 helps prevent output oscillations caused by input noise, enhancing system stability.

 

with a maximum input bias current of just 30nA, ensuring comparison accuracy. The power supply rejection ratio (PSRR) is a minimum of 70dB, helping to mitigate the impact of power supply noise on comparison results.

 

The MAX40003ANS02 employs an open-drain output structure, allowing the output to be pulled up to a voltage higher than VCC, facilitating level conversion functionality.

 

The operating temperature range spans -40°C to +125°C, meeting application demands in diverse harsh environmental conditions.

 

【Package and Mounting】

The MAX40003ANS02 employs a 4-bump wafer-level package (WLP) measuring just 0.73mm × 0.73mm. This package size is approximately equivalent to two 0402-sized resistors, occupying minimal PCB space and offering significant advantages for highly integrated portable devices.

 

Wafer-level packaging (WLP) enables the integrated circuit to be mounted face-down onto the printed circuit board (PCB), with the chip pads connected to PCB pads via a single solder ball. Unlike other CSPs based on ball grid arrays, leads, and laminates, this technology eliminates bonding wires or interposers. Its primary advantages include minimising inductance between the IC and PCB, reducing package size and manufacturing cycle time, and enhancing thermal conductivity.

 

Maxim provides detailed guidelines for PCB design and assembly processes: PCB pad surface treatment recommends electroless nickel immersion gold (ENIG); For all solder bump grid array packages, non-solder mask defined (NSMD) pads are always preferable to solder mask defined (SMD) pads; Solder mask is recommended between all pads.

 

【Application Areas】

The MAX40003ANS02 is ideally suited for portable electronic applications with stringent PCB space and power consumption constraints:

 

Mobile Consumer Electronics

Within devices such as smartphones, media players, and laptops, the MAX40003ANS02 can be employed for power monitoring, battery management, interface detection, and similar functions. Its miniature dimensions and ultra-low power characteristics make it exceptionally well-suited for these space- and power-sensitive applications.

 

Portable Medical Devices

Portable medical devices such as heart rate monitors, blood glucose meters, and portable diagnostic equipment demand exceptionally low component power consumption and high reliability. The MAX40003ANS02 excels in these applications due to its low power consumption and high accuracy.

 

Electronic Toys and Portable Instruments

Electronic toys and portable instruments typically require extended battery life while maintaining compact dimensions. The MAX40003ANS02's nano-level power consumption and miniature packaging perfectly meet these demands.
