In the CXAS42278, a 250Ω on-chip load resistor is added for quick output discharge (QOD) when the switch is turned off. The rise time of the device is internally controlled in order to avoid in-rush current and can be adjusted using a ceramic capacitor on the CTx pins. The CXAS42278 is available in 14 pin TDFN package.The CXAS42278 is dual N-channel MOSFET power switch designed for high-side load-switching applications, and the device has a typical RDS(ON) of 16mΩ and the output current is limited to 6A. Each switch is independently controlled by an on/off input (EN1, EN2), which is capable of interfacing directly with low-voltage GPIO control signals.
