The FA7612 is a small, ultra-low RON, single-channel load switch supporting a current up to 3A, allowing for a +12V or +5V power rail. The FA7612 is controlled by an on/off input, which is capable of interfacing directly with low-voltage control signals. A 250Ω on-chip load resistor is added for quick output discharge when the switch is turned off. The FA7612 provides under-voltage protection during soft-start. If a short circuit is present before power on, the device will be triggered UVP while start-up. The VOUT keep low until the short circuit remove. The device The FA7612 also integrates OTP against the fault conditions.
