ET3176数据手册ETEK中文资料规格书

描述 Description

The ET3176 is a dual-channel load switch with controlled turn on. The device contains two N-channel MOSFETs that can operate over an input voltage range of 0.6V to 5.7V and can support a maximum continuous current of 6A per channel. Each switch is independently controlled by an on and off input (ON1 and ON2),which can interface directly with low-voltage control signals. The ET3176 is capable of thermal shutdown when the junction temperature is above the threshold, turning the switch off. The switch turns on again when the junction temperature stabilizes to a safe range. The ET3176 also offers an optional integrated 230Ω on-chip load resistor for quick output discharge when the switch is turned off.The ET3176 is available in a small DFN14 package with thermal pad allowing for high power dissipation.
