ChargerLAB POWER-Z KM003C E-Marker Function Now Supports CYPD2803-Chargerlab

ChargerLAB POWER-Z KM003C tester has achieved another compatibility milestone. The latest firmware now fully supports the Infineon CYPD2803A1-09FNXI chip. Cables equipped with this chip can be quickly identified through the device's E-Marker reading function, allowing related chip information to be displayed clearly and intuitively.

The chip integrates a VCONN diode and Ra resistor, along with 47 bytes of internal memory for storing configuration data. It is designed for both single-chip and dual-chip passive cable applications, supports up to 48V/5A (240W) power delivery, and features an integrated oscillator that eliminates the need for an external clock source.

After upgrading the POWER-Z KM003C to the latest firmware, users can immediately test and read information from the chip.
