Product Details

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.


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.
