Small load switch has low on-resistance
The APE8937-HF-3 load switch measures 2 x 2mm and contains one N-channel MOSFET that can operate over an input range of 0.8 to 5.5V and support a maximum continuous current of up to 4A. On-resistance is very low with only 22mΩ from 1.8 to 5V input. The switch is controlled by an on/off input, and is capable of interfacing directly with control signals as low as 0.8V. Additional features include a 300Ω on-chip load resistor for output quick discharge when the switch is turned off. For power-sequencing, the rise time is adjustable by an external ceramic capacitor, which also reduces inrush current. It is supplied in an 8pin DFN package with thermal pad.
