CYPD7191-40LDXS

Application Specific Microcontrollers Overview

The Infineon CYPD7191-40LDXS is an AEC-Q100 Grade 2 qualified single-port USB Type-C controller with Power Delivery (PD) and a buck-boost converter. It features a 32-bit Arm Cortex-M0 processor, 128 KB Flash, and 16 KB SRAM. The device supports USB PD 3.2, including PPS and AVS modes, alongside legacy charging protocols like QC 3.0/4.0/5.0 and Apple fast charging. It operates on a 4 V to 24 V input (40 V tolerant) and provides a 3.3 V to 21.5 V output. The component integrates system-level fault protections such as OVP, OCP, and SCP.

Application Specific Microcontrollers Feature Summary

• USB PD 3.2 compliant with support for Programmable Power Supply (PPS) and Adaptive Voltage Supply (AVS).
• Integrated buck-boost controller with 150 kHz to 600 kHz switching frequency and programmable spread spectrum.
• On-chip 48 MHz Arm Cortex-M0 MCU with 128 KB Flash and 16 KB SRAM for custom application logic.
• Supports multiple legacy charging standards including Qualcomm QC 2.0/3.0/4.0/5.0, Apple 3A, and Samsung AFC.

Application Specific Microcontrollers Applications

• Automotive head unit (HU) chargers
• Rear seat entertainment (RSE) systems
• Rear seat chargers (RSC)

Application Specific Microcontrollers Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and temperature grade. Confirm that the selected variant matches the required integration level of external switching FETs. Ensure compliance with automotive qualification standards during sourcing.

Application Specific Microcontrollers Selection Notes

Select this part for applications requiring a single-port solution without integrated switching FETs. Compare with other EZ-PD CCG7S variants if internal FET integration is needed to reduce BOM. Verify that the 40-pin QFN package fits the target PCB layout constraints.

Application Specific Microcontrollers Part Context

This component belongs to the EZ-PD CCG7S family of automotive-grade controllers. It is designed specifically for high-reliability automotive environments, offering extensive programmability through its onboard MCU compared to fixed-function controllers.

Application Specific Microcontrollers Replacement Considerations

Check for updated revisions within the CYPD719x series or alternative grades in the EZ-PD CCG7S family. Verify pinout compatibility before substituting with other single-port USB-C controllers.
