Load switch offers low on-resistance and 4-A maximum continuous current
Advanced Power Electronics Corp. (San Jose, CA) launched a small load switch with controlled turn on and very low on-resistance. The APE8937-HF-3 load switch contains one N-channel MOSFET that can operate over a wide input voltage range from 0.8 V to 5.5 V and support a maximum continuous current of up to 4 A. On-resistance is low with 22 mΩ from VIN=1.8 V to VIN=5.0 V. The switch is controlled by an on/off input, and is capable of interfacing directly with control signals as low as 0.8 V. Additional features include:
- A 300-Ω on-chip load resistor for output quick discharge when the switch is turned off.
- Adjustable rise time by an external ceramic capacitor on the CT pin, which also reduces inrush current, for power-sequencing.
- Availability in a small, 2-mm x 2-mm 8-pin DFN package with thermal pad.
