Product details
Overview
CYPD3197-24LDXS 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 CYPD3197-24LDXS datasheet, CYPD3197-24LDXS pinout, CYPD3197-24LDXS application, or CYPD3197-24LDXS 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 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 detection. Its integrated current sense amplifier enables 100-mA resolution sensing across a 5-mΩ shunt for constant-current charging control.
Two PFET gate drivers (VBUS_P_CTRL with active pull-up; VBUS_C_CTRL requiring external pull-up) manage high-side and low-side VBUS path switching, while dual 8-bit SAR ADCs monitor temperature and charger voltage via GPIO/DP/DM multiplexing - all coordinated by the Cortex-M0 subsystem running custom firmware.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB PD Version | Complies with USB PD 3.0 v1.1 including Programmable Power Supply (PPS) mode for adaptive voltage/current negotiation. |
| MCU Core | Arm Cortex-M0 CPU with 64-KB flash and 8-KB SRAM, enabling field-updatable system management logic (e.g., thermal throttling, load sharing). |
| Operating Voltage | 3.0 V–24.5 V input range (30-V tolerant), supporting direct connection to automotive battery rails without external pre-regulation. |
| ESD Protection | ±8-kV contact / ±15-kV air-gap per IEC61000-4-2 Level 4C on CC1, CC2, DP0, DM0, P2.2, P2.3 pins - critical for connector hot-plug robustness. |
| Temperature Range | AEC-Q100 Grade 2 qualified (–40 °C to +105 °C ambient), validated for under-dash and infotainment head unit mounting locations. |
| Package | 24-pin QFN wettable flank (5 mm × 5 mm, 0.5-mm pitch), enabling automated optical inspection (AOI) of solder joints in automotive SMT lines. |
| VBUS Regulation | Integrated analog feedback loop with shunt regulator function supports constant-voltage (CV) and constant-current (CC) modes for USB PD contract enforcement. |

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 blocks; relies on external microcontroller for PD policy engine and QC/AFC decoding. | Suitable only for simple fixed-contract chargers (5 V/9 V/15 V), not adaptive PPS or multi-protocol legacy charging. | Select when cost sensitivity outweighs feature integration and firmware flexibility is handled externally. |
| NCP81239MNTXG | PD 2.0-only support; no PPS mode; no integrated ADC or temperature sensing; requires external VBUS discharge circuitry. | Limited to basic automotive USB-C charging without dynamic thermal/power management or firmware-upgradable features. | Choose only for legacy designs targeting PD 2.0 compliance and minimal bill-of-materials cost. |
Compared with STUSB4500QTR and NCP81239MNTXG, CYPD3197-24LDXS provides full PD 3.0 PPS, on-chip firmware execution, and integrated legacy charging detection - enabling single-chip solutions for adaptive, multi-protocol, thermally aware automotive chargers where BOM reduction and field-upgradability are critical.

FAQ
Does CYPD3197-24LDXS support USB PD 3.0 Programmable Power Supply (PPS) mode?
Yes, it fully complies with USB PD 3.0 v1.1 including PPS mode, enabling precise voltage adjustments in 20-mV steps and current control in 50-mA increments. This allows dynamic optimization of power delivery for fast-charging smartphones and laptops, with regulation accuracy maintained across the full –40 °C to +105 °C operating range.
What is the maximum VBUS input voltage the device can tolerate during fault conditions?
CYPD3197-24LDXS supports 30-V absolute maximum rating on VBUS_IN_DISCHARGE and withstands VBUS-to-CC shorts up to 22 VDC for 1000 hours. Its integrated VBUS short protection circuitry clamps transient ringing voltages (e.g., up to 44 V observed in unclamped cables) using on-chip ESD diodes, preventing latch-up or permanent damage.
Can the device operate without an external crystal or oscillator?
Yes, it integrates a factory-trimmed internal oscillator sufficient for USB PD BMC timing and system clock generation, eliminating the need for external crystals. The oscillator supports full-speed USB communication and meets USB specification jitter requirements without additional components or layout complexity.
How many independent USB charging protocols does the device support simultaneously?
CYPD3197-24LDXS supports QC 4.0, Apple 2.4A, AFC, and BC 1.2 concurrently on both DP0/DM0 and DP1/DM1 pairs. Its dual charger detection blocks allow simultaneous identification and negotiation with two legacy devices - for example, a QC 4.0 phone on Type-A and an Apple tablet on Type-C - without firmware arbitration delay.
