Analog Devices Inc. MAX25430AATLF/V+ Port Controller/Protector

Analog Devices MAX25430AATLF/V+ Port Controller/Protector combines an automotive-grade buck-boost controller, a USB-PD Analog Front-End (AFE), legacy USB Charging support, and USB Type-C™ protection. USB Type-C protection provides automotive system-level ESD and 24V short-circuit protection for D+, D-, CC1, CC2, and VCONN. The device also supports legacy USB 2.0 charging modes including BC1.2, Apple® 2.4A, Apple CarPlay®, Apple MFi, and USB On-The-Go (OTG). The MAX25430B integrates a USB-PD AFE which supports the USB-IF Type-C Port Controller Interface (TCPCI) specification and interfaces with any I2C Master in the application.

Features

  • USB-PD PHY that is TCPCI standard for use with any low-cost I2C Master such as Hub IC, MCU, or SOC (MAX25430B), ground-offset-adjusted BMC PHY for maximum signal-to-noise ratio
  • Non-TCPC versions available for protecting external USB-PD controller (MAX25430A)
  • Integrated buck-boost controller for external H-bridge
    • 4.5V to 36V input operating range
    • Fixed PDO 5V, 9V, 15V, and 20V up to 5.0A
    • 220kHz, 300kHz or 400kHz switching frequency
    • External frequency synchronization and spread spectrum for reduced EMI
  • Integrated and user-programmable buck-boost output voltage adjustment up to 500mΩ of cable resistance
  • Integrated 3.0V to 5.5V 1W smart, reliable VCONN switch with protection
  • Highest performance, safest, and lowest cost passenger cable-shield short-to-battery protection, minimizes short-circuit currents with a small, single-FET solution
  • Integrated 24V protection on HVD+, HVD-, HVCC1, and HVCC2
  • Integrated legacy USB 2.0 charging support including BC1.2, Apple CarPlay, MFi R33, and OTG
  • Integrated ±15kV air, ±8kV contact ISO 10605 and IEC 61000-4-2 ESD protection
  • -40°C to +125°C operating temperature range
  • 40-pin (6mm x 6mm) TQFN package with EP
  • AEC-Q100 and AEC-Q006 qualified

Applications

  • USB hubs, breakout boxes, and multimedia hubs
  • Dedicated charging modules
  • Rear-seat entertainment modules
