The maximum current rating of the TPS2421-2DDAR is 2.5A per channel, with a total current limit of 5A for both channels.
To configure the TPS2421-2DDAR for USB-C PD applications, connect the CC1 and CC2 pins to the CC lines of the USB-C connector, and use the I2C interface to configure the power delivery profiles.
The EN (enable) pin is used to enable or disable the power switches. When the EN pin is high, the power switches are enabled, and when it is low, the power switches are disabled.
The TPS2421-2DDAR has built-in current and voltage monitoring capabilities. The current sense pins (ISEN1 and ISEN2) can be used to monitor the current, and the voltage sense pins (VSEN1 and VSEN2) can be used to monitor the voltage.
The thermal shutdown temperature of the TPS2421-2DDAR is 150°C. If the junction temperature exceeds this value, the device will shut down to prevent damage.
