The MAX25432 combines an automotive-grade buck-boost controller capable of full-range 3.3V to 21V programmable power supply (PPS) at up to 6.35A, a USB Power Delivery (USB PD) analog front-end (AFE), legacy USB charging support, and USB Type-C® protection switches for automotive USB host or downstream-facing (DFP) applications. The USB Type-C protection switches provide automotive system-level ESD protection and 24V short-circuit protection for D+, D-, CC1, CC2, and VCONN. The device can optionally support legacy charging modes for older passenger phones including BC1.2, Apple® Charge, Apple CarPlay®, Apple MFi, and USB On-The-Go (OTG).


The MAX25432B integrates a USB PD AFE, which supports the USB-IF Type-C Port Controller Interface (TCPCI) specification and can interface with any I2C master in the application. The MAX25432A provides configuration channel (CC) signal pass-through protection for an external USB PD controller.


P-suffix and G-suffix devices include intelligent detection and protection to avoid high short-circuit currents flowing from the car battery through the cable shield to ground during fault events, thus preventing car module damage.


The MAX25432 is available in a small, 6mm x 6mm, 40-pin TQFN-EP package and requires very few external components. The MAX25432 evaluation (EV) kit and collateral provide a convenient platform to the design engineer for rapid evaluation with reduced test and firmware development time.

Applications

  • Dedicated Charging Modules
  • Head Unit, Radio, Navigation
  • Rear-Seat Entertainment Modules
  • USB Hubs, Breakout Boxes, and Multimedia Hubs

Product Detail

The MAX25432 EV kit and collateral provides a convenient platform to the design engineer for rapid evaluation with reduced test and firmware-development time.

The MAX25432B evaluation kit (EV kit) features MAX25432BATLG/V+ automotive 100W USB-PD PPS buck-boost port controller and protector for head-unit, multi-media hub, rear-seat infotainment, and dedicated charging port (DCP) applications.

The IC combines an automotive-grade buck-boost controller capable of full range PPS 3.3V-21V at up to 6.35A, a USB-PD analog front-end (AFE), legacy USB charging support and USB Type-C® protection switches for automotive USB host or DFP applications.

The integrated USB Type-C protection switches provide 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 USB-PD source capabilities and I2C registers can be changed using the PC GUI software available for download.

The EV kit also allows evaluation of the intelligent shield short-to-battery detection and protection available on MAX25432. This feature protects against high shortcircuit currents flowing from the car battery through the cable shield to module ground during fault events, preventing car module damage.

Automotive USB-PD reference designs are also available. contact Maxim Integrated for more information.
