Excelliance MOS EM5220
The EM5220 is a single channel load switch with programmable rise time and with an integrated output discharge control. The device contains a P-channel NOSFET that can operate over an input voltage range of 4.5V to 10V. The switch is controlled by an on and off low level logic input, which is capable of interfacing with GPIO signals.GENERAL DESCRIPTION
The programmable rise time of the device can reduces inrush current caused by large load capacitances during power up. The configurable DIS pin controls the on/off time of the device to allow design flexibility for controlling the power on/off sequence.APPLICATIONS
