Infineon Technologies CYPD717140LQXQXQLA1

Overview

CYPD717140LQXQXQLA1 from Infineon is a single-port USB Type-C Power Delivery (PD) 3.1 controller with integrated buck-boost regulator, Arm® Cortex®-M0 MCU (48 MHz, 128 KB flash), 4–24 V input (40 V tolerant), 3.3–21.5 V output, and support for Programmable Power Supply (PPS) at 20-mV/50-mA steps-designed for cigarette lighter adapters and compact wall chargers.

For engineers reviewing the CYPD717140LQXQXQLA1 datasheet, CYPD717140LQXQXQLA1 pinout, CYPD717140LQXQXQLA1 application, or CYPD717140LQXQXQLA1 equivalent, this device delivers full USB PD 3.1 compliance-including extended messaging, PPS regulation, hardware-controlled VBUS protection, and legacy charging (QC 5.0, AFC, Apple 2.4 A)-in a 40-pin QFN package with industrial temperature range (−40°C to +105°C).

Technical Context

The device integrates three co-located subsystems: a USB PD 3.1 PHY with BMC encoding/decoding, configurable Rp/Rd, VCONN 100-mW supply, and VBUS-to-CC short protection; a digitally controlled buck-boost converter with selectable PSM/FCCM modes, soft-start, and spread-spectrum modulation; and a 48-MHz Cortex-M0 MCU with 16-KB SRAM, 2×8-bit ADCs, 8×TCPWMs, and 3×SCBs (I²C/SPI/UART/LIN).

Hardware-level fault management includes on-chip VBUS OVP/OCP/UVP (configurable thresholds), overtemperature detection via internal sensor or external thermistors, and gate drivers for high-side NFET switching-enabling autonomous protection without host intervention during transient faults or thermal events.

FAQ

What USB PD specification versions does CYPD717140LQXQXQLA1 support?

CYPD717140LQXQXQLA1 fully supports USB PD 3.1, including Programmable Power Supply (PPS) mode, extended messaging (up to 260 bytes with chunking), and all mandatory features of PD 3.0 and 2.0. It implements BMC physical layer with collision avoidance and hardware-based Rp/Rd switching per USB Type-C 2.1 specification.

Does this device require an external crystal or oscillator?

No. CYPD717140LQXQXQLA1 includes a fully integrated oscillator and clock generation system-eliminating the need for any external crystal, resonator, or clock source. The internal oscillator provides timing for the Cortex-M0 core, USB PD PHY, and buck-boost controller with ±2% frequency stability over temperature and voltage.

Can the buck-boost controller operate in standalone mode without MCU firmware?

No. The buck-boost controller is tightly coupled to the Cortex-M0 subsystem and requires firmware initialization and runtime control. All configuration-including voltage setpoint, current limit, switching frequency, and protection thresholds-is managed via registers accessible only through the MCU or EZ-PD™ configuration utility.

How many GPIOs are available for custom system functions?

CYPD717140LQXQXQLA1 provides up to 13 GPIOs, two of which are high-voltage tolerant (supporting up to 24 V) for direct sensing of VBUS or adapter presence. These pins support multiple functions including PWM output, ADC input, SCB interface, and interrupt generation-enabling custom power throttling, LED status indication, or thermistor monitoring without external logic.
