Product details
Overview
CYPD3195-24LDXST 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, 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 CYPD3195-24LDXST datasheet, CYPD3195-24LDXST pinout, CYPD3195-24LDXST application, or CYPD3195-24LDXST 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 hardware-based OVP/OCP/SCP fault protection for automotive power delivery systems.
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 enforcement. Its integrated high-voltage regulator enables direct VBUS_IN_DISCHARGE input (3.0–24.5 V) with internal 3.3-V VDDD generation.
Two 8-bit SAR ADCs interface with GPIOs and DP/DM pins 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 load-sharing control; and two PFET gate drivers (VBUS_P_CTRL active pull-up, VBUS_C_CTRL open-drain) manage external pass FETs in 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 | Lacks integrated MCU, flash, and legacy charger detection; requires external microcontroller for PD policy management. | Suitable for cost-sensitive non-automotive chargers where firmware customization is not required. | Select when BOM simplicity outweighs need for field-upgradable PD logic or proprietary charging support. |
| TPS65987D-LP | Includes integrated DC/DC converter and higher PD power handling (100 W), but no Type-A port support or built-in BC 1.2/Apple/QC detection. | Targeted at high-power laptop docks rather than automotive dual-port chargers with legacy compatibility needs. | Choose for >60-W applications needing native buck conversion, but avoid when Type-A backward compatibility is mandatory. |
Compared with STUSB4500QTR and TPS65987D-LP, CYPD3195-24LDXST uniquely combines AEC-Q100 qualification, dual-port (Type-C + Type-A) support, integrated legacy charger detection, and field-programmable MCU in a single wettable flank QFN-making it the only solution optimized for automotive rear-seat charging systems requiring both USB PD 3.0 and broad proprietary protocol coverage.

FAQ
What is the maximum VBUS input voltage the CYPD3195-24LDXST can tolerate?
The CYPD3195-24LDXST supports a VBUS_IN_DISCHARGE input range of 3.0 V to 24.5 V and is rated for 30-V absolute maximum tolerance. Its VBUS short protection circuitry handles sustained 17 V and transient exposure up to 22 V for 1000 hours on CC1, CC2, P2.2, and P2.3 pins-critical for automotive battery rail fluctuations and load dump events.
Does the CYPD3195-24LDXST support firmware updates in the field?
Yes. The device supports over-the-air firmware updates via the CC interface using Application Firmware Update (AFU) protocol defined in USB PD specification. This enables OEMs to deploy new charging policies, fix interoperability issues, or add support for emerging proprietary protocols without hardware modification.
How does the integrated current sense amplifier function in charging applications?
The low-side current sense amplifier detects current through a 5-mΩ external shunt resistor with 100-mA resolution, enabling precise constant-current regulation during PD contract negotiation. It feeds directly into the MCU subsystem, allowing closed-loop VBUS current control without external op-amps or ADCs-reducing component count and layout complexity.
Can the CYPD3195-24LDXST operate without an external crystal oscillator?
Yes. The device integrates a factory-trimmed internal oscillator that eliminates the need for an external crystal. It provides sufficient accuracy for USB PD BMC timing requirements and supports clock gating for low-power Deep Sleep modes-reducing BOM cost and board space in space-constrained automotive modules.
