Analog Devices Inc./Maxim Integrated MAX25252ATIA/VY+

Overview

MAX25252ATIA/VY+ from Analog Devices / Maxim Integrated is a five-output ASIL B PMIC for next-generation automotive camera sensors. The device integrates one high-voltage synchronous buck converter, two 1.7A low-voltage buck converters, and two high-PSRR LDO rails so high-megapixel cameras and high-speed serializers can be powered from a compact monitored PMIC.

As part of the MAX25252 product family, MAX25252ATIA/VY+ combines 3.5V to 22V power-over-coax input support, I2C-programmable output voltages and sequencing, OV/UV monitoring on all outputs, RESET diagnostics, NTC temperature monitoring with a 12-bit ADC, spread-spectrum EMI reduction, ASIL B compliance, and AEC-Q100 qualification. For engineers reviewing the MAX25252ATIA/VY+ datasheet, MAX25252ATIA/VY+ pinout, MAX25252ATIA/VY+ application, or MAX25252ATIA/VY+ equivalent, this device is widely used in surround-view cameras, rear-view cameras, side-view cameras, forward-looking cameras, high-megapixel image sensors, and automotive serializer power systems.

Technical Context

In automotive camera modules, MAX25252ATIA/VY+ uses OUT1 as a 1A high-voltage synchronous buck converter operating from a 3.5V to 22V power-over-coax input. OUT1 can generate 2.5V to 5V in 100mV steps and supports the upstream rail structure for the lower-voltage outputs.

OUT2 and OUT3 are low-voltage synchronous bucks that deliver up to 1.7A each across a 0.75V to 3.9375V programmable range. LDO4 supplies up to 0.4A for low-noise camera-sensor rails, and LDO5 supplies up to 0.9A for secondary imager or serializer rails.

MAX25252ATIA/VY+ is commonly used when camera power requires I2C-controlled sequencing, 2.1MHz forced-PWM switching, spread-spectrum EMI behavior, RESET-based OV/UV diagnostics, board-temperature measurement through an NTC input, and a 28-pin side-wettable TQFN package for automotive inspection.

Key Specifications

Pinout & Package

The MAX25252ATIA/VY+ pinout includes high-voltage input and switch pins for OUT1, low-voltage buck pins for OUT2 and OUT3, LDO4 and LDO5 outputs, SDA/SCL I2C pins, RESET diagnostics, NTC temperature input, enable and sequencing controls, and exposed thermal ground.

For PCB design, OUT1 power-over-coax input filtering should be close to the IC, each buck inductor loop should be compact, LDO output capacitors should sit near their pins, and I2C/RESET/NTC traces should be routed away from LX switching copper.

Key Features

• Five integrated outputs reduce camera-module regulator count.
• OUT1 supports 3.5V to 22V power-over-coax input operation.
• Two 1.7A low-voltage bucks support high-megapixel sensors and serializers.
• LDO4 and LDO5 provide low-noise secondary camera rails.
• I2C programming and RESET diagnostics support monitored startup.
• ASIL B compliance, AEC-Q100 qualification, and NTC temperature monitoring support automotive safety reviews.

Applications

Equivalent & Alternatives

When evaluating a MAX25252ATIA/VY+ equivalent, engineers should compare output count, OUT1 input range, low-voltage buck current, LDO current, I2C programming, temperature monitoring, ASIL documentation, and package.

Compared with MAX25249ATPA/VY+, MAX25252ATIA/VY+ adds a five-output structure with two LDO rails and temperature monitoring for newer camera sensors. MAX25252ATIA/VY+ vs MAX20428ATIA/VY+ selection depends on whether the design needs a camera-focused five-output PMIC or a broader ADAS multi-output power architecture.

Quality

MAX25252ATIA/VY+ should be sourced as original Analog Devices / Maxim Integrated components through traceable supply channels. Quality checks may include side-wettable TQFN inspection, top-mark validation, solderability testing, output-voltage verification, I2C communication testing, RESET diagnostics, and AEC-Q100 documentation review.

Production validation should include OUT1 power-over-coax startup, OUT2/OUT3 transient behavior, LDO noise and load regulation, OV/UV thresholds, NTC temperature accuracy, spread-spectrum EMI behavior, thermal rise, and short-circuit protection.

Availability

MAX25252ATIA/VY+ available at Aetrix Electronics and is suitable for automotive camera, surround-view, rear-view, side-view, forward-looking, serializer, and high-megapixel image-sensor power systems.

Supply support may include volume procurement planning, scheduled delivery arrangements, traceable sourcing management, and long-term supply support for OEM, industrial electronics, automotive electronics, and embedded product programs. Sample and NPI supply support, as well as urgent in-stock supply support, can also be arranged for prototype builds, pilot runs, and time-critical production needs.

For production builds, confirming output configuration, I2C setup, package, ASIL documentation, lifecycle status, lead time, and sourcing continuity helps reduce procurement risk.
