GMT（致新） G2898KD1U TDFN2X3-14 双超低通阻负载开关 与控制刺激

　　General Description

　　The G2898 is dual N-channel MOSFET power switch

　　designed for high-side load-switching application. The

　　device has a typical RDS(ON) of 16mΩ and the output

　　current is limited to 6A. Each channel is controlled by

　　an on/off input (EN1, EN2) independently, which is

　　suitable for interfacing directly with low-voltage I/O

　　ports.

　　In the G2898, a 220Ω on-chip load resistor is added

　　for quick output discharge (QOD) when the switch is

　　turned off. Moreover, the controlled rise time can be

　　adjusted by using a ceramic capacitor on the CTx pins

　　in order to prevent in-rush current at start-up time.

　　The G2898 is available in 14 pin TDFN package.
