Key features
- BISS transistor and RET in one package
- Low 鈥渢hreshold鈥?voltage (< 1 V) compared
to MOSFET
- Small drive power required
- Best-in-class performance for loadswitches
- Available for switching loads of 0.5 鈥?1 A
Key bene鏗乼s
- Integrated on-the-shelve solution for
switching loads
鈥?Saves design and sourcing costs
鈥?Reduction in boardspace requirements
鈥?Just one or two external resistors needed
for full loadswitch capability
- Combination of low voltage drop and low
base drive current
鈥?BISS transistor in the power path provides
the lowest energy-losses
鈥?RET in the control path provides a low
base drive current
