Product details
Overview
CYPD3195-24LDXS 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, supports QC 4.0/Apple 2.4A/AFC/BC 1.2 charging protocols, and operates across –40 °C to +105 °C in rear-seat automotive chargers.
For engineers reviewing the CYPD3195-24LDXS datasheet, CYPD3195-24LDXS pinout, CYPD3195-24LDXS application, or CYPD3195-24LDXS equivalent, key selection criteria include AEC-Q100 qualification, integrated VBUS discharge FETs, ±8-kV contact ESD on CC pins, 24-pin wettable flank QFN package, and programmable current sense amplifier for constant-current charging control.
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 integrated RP/RD termination switching for DFP role detection. Its high-voltage regulator supports 3.0–24.5 V input with 30-V tolerance and provides analog feedback control of VBUS voltage per negotiated PD contract.
Two 8-bit SAR ADCs interface with GPIOs and DP/DM lines for charger detection and temperature monitoring; dual SCBs support I²C (up to 1 Mbps), SPI, or UART; four TCPWM blocks enable PWM-based power throttling and quadrature decoding; and two PFET gate drivers (VBUS_P_CTRL active pull-up, VBUS_C_CTRL open-drain) manage external pass FETs on provider/consumer paths.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB Type-C port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Standalone USB PD 3.0 controller (no MCU); requires external microcontroller for custom logic and charger detection. | Lacks integrated ADC, TCPWM, and proprietary charging blocks - unsuitable for QC 4.0 or AFC detection without additional ICs. | Select when only basic PD negotiation is needed and system already includes a capable host MCU. |
| TPS65987D-SR | TI USB PD controller with integrated DC/DC converter; supports dual-C port but no Type-A legacy charging detection. | No built-in BC 1.2 or Apple/QC/AFC detection circuitry - requires companion IC or firmware workaround for multi-protocol support. | Prefer for high-density dual-C port designs where integrated buck converter simplifies power architecture. |
Compared with STUSB4500QTR and TPS65987D-SR, CYPD3195-24LDXS uniquely combines AEC-Q100 qualification, full legacy charging support, and programmable MCU resources in a single wettable flank QFN - enabling BOM reduction and functional consolidation in automotive charging systems.

FAQ
What is the maximum VBUS voltage the CYPD3195-24LDXS can regulate?
The device regulates VBUS up to 20 V in constant-voltage mode per USB PD 3.0 specifications. Its VBUS_IN_DISCHARGE pin tolerates up to 30 V absolute maximum, and its integrated shunt regulator supports analog feedback control across the full 5–20 V PD contract range with ±1% accuracy under nominal conditions.
Does CYPD3195-24LDXS support USB Power Delivery Alternate Modes?
No - CYPD3195-24LDXS is designed exclusively for USB PD power contract negotiation and legacy charging. It does not implement DisplayPort Alt Mode, Thunderbolt, or other data tunneling protocols. Its DP/DM pins serve only for BC 1.2 and proprietary charger detection, not video/data transmission.
How is firmware updated in the field?
Firmware updates occur over the CC line using the Application Firmware Update (AFU) protocol defined in the USB PD specification. The device supports authenticated, encrypted updates via the CC interface without requiring SWD debug access, enabling secure over-the-air updates in deployed automotive systems.
What fault protections are implemented in hardware versus firmware?
Hardware-implemented protections include VBUS OVP/OCP/UVP/SCP, CC-to-VBUS short protection, and ESD clamping. Firmware-managed functions include thermal throttling, power state transitions, and charger protocol handshaking - all running on the integrated Cortex-M0 with real-time response to hardware fault interrupts.
