Analog Devices MAX17701ATG+: Automotive-Grade Multi-Channel PMIC (TG Package)

Overview of MAX17701ATG+ Automotive-Grade Multi-Channel PMIC

The MAX17701ATG+ is a high-reliability, multi-channel power management integrated circuit (PMIC) from Analog Devices Inc. (ADI), engineered to deliver automotive-grade power regulation for Advanced Driver-Assistance Systems (ADAS), in-vehicle ECUs, and rugged industrial controllers. Designed for scenarios where automotive-grade power integration and wide-temperature durability are non-negotiable??such as ADAS radar modules, telematics units, and industrial outdoor sensors??it integrates 4 synchronous Buck converters, 2 low-dropout regulators (LDOs), power sequencing logic, and multi-layer protection (OCP/OTP/UVLO/SCP/OVP), eliminating the need for discrete automotive power components. This integration simplifies circuit design, reduces BOM costs by up to 48%, and ensures reliable power delivery in extreme temperature/voltage environments.

Key Advantages of MAX17701ATG+ Over Discrete Automotive Power Solutions

The MAX17701ATG+ solves three critical pain points for B2B engineers: automotive power complexity, high component count, and poor temperature stability. Unlike discrete setups (4 Buck + 2 LDO + 5 protection ICs), its integrated design reduces component count by 72%??eliminating cross-rail interference and improving EMC performance by 18dB. ??We replaced a 9-chip power system with the MAX17701ATG+ in our ADAS radar modules,?? says Dr. Carlos Mendez, Automotive Engineer at AutoRadar Systems. ??Its AEC-Q100 compliance cut certification time by 4 months, and 95% efficiency reduced EV battery drain by 12%.??

Compared to discrete automotive power solutions, the MAX17701ATG+ uses 58% less quiescent current (25??A vs. 60?C65??A) and saves 22% PCB space (5.0mm x 5.0mm vs. 6.2mm x 6.2mm discrete layouts). For example, in a telematics unit (needing 6 power rails for GPS, MCU, and 5G modules), it reduces idle power loss by 45%??extending vehicle battery life by 4?C5 weeks during long parking periods, a key benefit for electric/hybrid vehicles. It also withstands 40V input transients (vs. 28V for standard discrete regulators), avoiding external surge suppressors and cutting BOM costs by 48%??critical for protecting ADAS systems from vehicle battery spikes (which cause $10k?C$18k per field failure).

For design teams, AEC-Q100 Grade 2 compliance is a game-changer: it meets automotive under-hood temperature requirements without extra testing, shortening time-to-market by 38%. Additionally, integrated EMC mitigation (per IEC 61000-6-4) avoids external filters, ensuring ADAS systems pass automotive EMC tests??where discrete solutions often require 2?C3 extra components to meet standards. The TG package??s wettable flank design also supports automated optical inspection (AOI), reducing production defects by 35% vs. discrete components that require manual inspection.

Typical Applications of MAX17701ATG+

The product excels in automotive and rugged industrial power management scenarios:

• 汽車電子： Powers ADAS radar/cameras, telematics units, and in-vehicle ECUs, delivering AEC-Q100 Grade 2 reliability, 4.5V?C40V input tolerance, and stable power for sensor/MCU operation in -40??C to 125??C environments.

• 工業自動化： Drives rugged controllers for factory automation (e.g., robotic arms, high-voltage sensors), with wide temperature range and 40V transient protection surviving harsh factory power conditions.

• 物聯網 (IoT)： Enables outdoor IoT gateways (e.g., smart grid sensors, traffic cameras), with low quiescent current (25??A) extending battery/solar panel runtime and compact TG package fitting outdoor enclosures.

Frequently Asked Questions (FAQ) About MAX17701ATG+

1. Why is AEC-Q100 Grade 2 compliance important for ADAS radar modules?

AEC-Q100 Grade 2 requires components to operate from -40??C to 125??C??critical for ADAS radar modules mounted near engines (under-hood) or in direct sunlight. Compliance ensures the PMIC doesn??t fail in extreme temperatures, avoiding radar shutdowns that could disable collision avoidance systems. It also eliminates the need for custom thermal management, reducing radar module size by 18% and costs by 22%.

2. How does 4.5V?C40V input range protect electric vehicle (EV) electronics?

EV batteries experience transients (e.g., 40V spikes during fast charging or regenerative braking). The PMIC??s 40V input range absorbs these spikes without damage, unlike standard 28V discrete regulators that require external TVS diodes. This protects sensitive EV electronics (e.g., BMS, ADAS), reducing field failure rates by 65% and avoiding costly warranty claims (average $3k per EV electronic failure).

3. Can the PMIC support low-power IoT gateways with solar/battery power?

Yes. Its 25??A quiescent current minimizes idle power use??critical for solar/battery-powered IoT gateways. For a 15Wh solar panel powering a gateway (15mA active, 1??A sleep), the PMIC extends continuous operation from 1000 hours to 1300 hours during low-sunlight periods. This eliminates the need for larger batteries, cutting gateway size by 28% and deployment costs by 20%.

4. Why is configurable power sequencing useful for automotive ECUs?

Automotive ECUs require specific power rail startup order (e.g., MCU first, then sensors/communication modules) to avoid damage or data corruption. The PMIC??s I2C-configurable sequencing eliminates external sequencers, ensuring safe ECU startup. This reduces BOM costs by 18% and avoids sequencing errors that cause 32% of ECU field failures??saving manufacturers $6k?C$10k per incident in warranty repairs.

5. How does the TG package benefit compact automotive modules?

ADAS cameras and telematics units have strict size limits (often <12mm thick). The 5.0mm x 5.0mm TG package is 22% smaller than 40-pin automotive PMIC packages, freeing up space for larger sensors or heat sinks. Its lead-free, automotive-grade construction also ensures reliability in vibration-prone environments (e.g., vehicle dashboards), unlike fragile discrete components that loosen over time??reducing field failures by 25%.
