Product details
Overview
CYPD3196-24LDXST from Infineon Technologies (formerly Cypress) is an automotive-grade USB Type-C port controller with integrated Arm® Cortex®-M0 MCU, 64-KB flash, USB PD 3.0 v1.1 compliance, and dual-port support (one Type-C + one Type-A). It delivers VBUS regulation via integrated shunt regulator, ±8-kV contact ESD on CC pins, and operates across –40 °C to +105 °C for rear-seat charger and infotainment head unit applications.
For engineers reviewing the CYPD3196-24LDXST datasheet, CYPD3196-24LDXST pinout, CYPD3196-24LDXST application, or CYPD3196-24LDXST equivalent, key selection criteria include AEC-Q100 qualification, integrated PFET gate drivers for VBUS path control, dual 8-bit SAR ADCs for temperature/power monitoring, and native support for QC 4.0, Apple 2.4A, AFC, and BC 1.2 legacy charging protocols.
Technical Context
The device implements a full USB PD 3.0 physical layer with BMC encoding/decoding on CC lines, collision-avoidance half-duplex communication, and programmable RP/RD termination for DFP role detection. Its integrated high-voltage regulator supports VBUS control in constant-voltage or constant-current mode using external feedback resistors and a current sense amplifier with 100-mA resolution across a 5-mΩ shunt.
Two SCBs provide configurable I²C/SPI/UART interfaces up to 1 Mbps (Fast-mode Plus), while four TCPWM blocks enable timing-critical functions like load-sharing duty-cycle management and VBUS discharge timing. The MCU subsystem includes SWD debug, 8-KB SRAM, and hardware OVP/OCP/SCP/UVP protection triggered independently per fault condition.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Standalone USB PD 3.0 controller without integrated MCU; no flash/SRAM; relies on external host for policy engine. | Lacks firmware programmability for custom charging profiles or thermal algorithms; limited to fixed PD contracts. | Select when cost-sensitive designs require minimal BOM but accept reduced flexibility in power management logic. |
| TPS65987D-64RGER | TI USB PD controller with integrated buck-boost converter; no AEC-Q100 qualification; commercial temp range only. | Not rated for automotive under-hood or cabin environments; unsuitable for rear-seat chargers operating above 85 °C ambient. | Select for non-automotive industrial docking stations where extended temperature operation is not required. |
