USB Type C PMIC 40-TQFN (6x6)
The MAX25432 combines an automotive-grade buckboost controller capable of full-range 3.3V to 21V
programmable power supply (PPS) at up to 6.35A, 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 TypeC 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
controller 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.
