Overview
The MAX9612AUB+T is a high-side current-sense amplifier featuring an integrated 12-bit ADC and a selectable op amp or comparator. It operates over a 0V to 60V common-mode voltage range with a 2.7V to 5.5V supply. The device provides programmable gains of 1x, 4x, and 8x for sense voltages up to 440mV. It includes an I2C interface compatible with 1.8V and 3.3V logic, supporting 16 addresses. The package is a 10-pin µMAX (3mm x 5mm), rated for -40°C to +125°C.
Feature Summary
- Integrated 12-bit ADC capable of reading sense voltage, common-mode voltage, SET voltage, OUT voltage, and die temperature.
- Internal selectable op amp or comparator with watchdog, latch, and retry functionality for fault monitoring.
- Wide 0V to 60V input common-mode voltage range with low input bias and offset currents.
- I2C bus interface compatible with 1.8V and 3.3V logic levels.
Applications
- Hybrid Automotive Power Supplies
- Server Backplanes
- Base-Station PA Control
- Base-Station Feeder Cable Bias-T
- Battery-Operated Equipment
Procurement Notes
Verify the specific suffix 'AUB+T' against the manufacturer's official documentation to confirm the inverting configuration, µMAX package, and tape-and-reel delivery format. Ensure compatibility with the required I2C logic levels and operating temperature range before integration into the design.
Selection Notes
Select this component when a high-side current-sense solution requires simultaneous analog control via an internal op amp/comparator and digital monitoring via an integrated ADC. The MAX9612 is specifically chosen for its inverting input-to-output configuration compared to the noninverting MAX9611. Consider the 10-pin µMAX package constraints and the need for I2C communication for system integration.
Part Context
The MAX9612 belongs to the MAX9611/MAX9612 family of high-side current-sense amplifiers from Analog Devices/Maxim Integrated. These devices are designed for industrial and automotive applications requiring precise current measurement and fault protection. The MAX9612 variant is distinguished by its inverting input-to-output configuration, whereas the MAX9611 offers a noninverting configuration.
Replacement Considerations
The MAX9611AUB+T is a functional substitute within the same family, differing only in having a noninverting input-to-output configuration instead of the MAX9612's inverting configuration.
FAQ
What is the difference between the MAX9611 and MAX9612?
The MAX9611 features a noninverting input-to-output configuration, while the MAX9612 features an inverting input-to-output configuration.
Can the internal amplifier be used as a comparator?
Yes, the internal amplifier can be configured as a comparator using the Control Register. This mode supports latched and retry functionality for fault events.
What variables can the integrated ADC measure?
The ADC can measure the voltage across the sense resistor (VSENSE), the input common-mode voltage (VRSCM), the op-amp/comparator output (VOUT), the SET reference voltage, and the internal die temperature.
