Version Introduction: The EV2400 Panda version allows fixed voltage output. It retains a single communication capability of 4 protocols and can be used to manually read and write battery parameters. Dual over-current protection. Double over-temperature protection. 6-way isolation. 11-way anti-static. 4 types of communication. Power supply anti-backfilling. USB powered. Built-in pull-up resistor. IO withstand voltage 100V. It has 4 ports and supports 4 protocols Input interface: USB B; Output interface: KF2510 x 4; PORT1 (SMB): Supported; PORT2 (): Supported; PORT3 (HDQ): Yes; PORT4 (SW): Supported; Tri-status LED: Yes; CPU power supply: Yes; Output power supply: 1-way; IO port isolation: multi-chip; CPU power supply capacity: 150mA; Maximum source current: 200uA; Isolation bandwidth: 1Mhz; IO port over-voltage strategy: 100V withstand voltage Protection: Output anti-backfilling: Yes; Over-current protection: chip; IO port anti-negative voltage: support; IO port current limiting: Yes; VOUT current limit: Yes; VOUT over-temperature protection: 1-way; Power supply over-temperature protection: Yes; USB anti-backfilling: Yes; Number of ESD protection: 11 ways Note: Output power supply: It allows different ports to connect different system chips, so that there is no series connection. Maximum source current: It allows more devices to be hung on the communication bus. Isolated bandwidth: It improves communication accuracy, which is conducive to reducing communication interference and bit errors. IO port over-voltage strategy: burn your devices or other devices if wrong wire is connected. Attention: Battery is not included in the package. It can solve most battery software problems, but it cannot solve battery hardware failures. During normal debugging, only VSS, SDA and S cables need to be connected, and Vout is disconnected. Vout is a function pin, not a power pin. Please not connect Vout when connecting the battery. When debugging the battery, do not turn on the battery to prevent short circuits. Connected to a computer for the first time, the EV2400 Panda automatically detect and activate for about 1 second, without user operation. After activation, install and open the bqstudio software to recognize the device and firmware version.
