Combining a BISS transistor with a RET, BISS Loadswitches provide full

miniature loadswitch functionality in a single package and deliver

best-in-class performance.

Key features

- BISS transistor and RET in one package

- Low “threshold” voltage (< 1 V) compared

to MOSFET

- Small drive power required

- Best-in-class performance for loadswitches

- Available for switching loads of 0.5 – 1 A

Key benefits

- Integrated on-the-shelve solution for

switching loads

• Saves design and sourcing costs

• Reduction in boardspace requirements

• Just one or two external resistors needed

for full loadswitch capability

- Combination of low voltage drop and low

base drive current

• BISS transistor in the power path provides

the lowest energy-losses

• RET in the control path provides a low

base drive current

Key applications

- Supply line switches, e.g. in control units

- Control of lamps, motors and switches,

e.g. instrument clusters

- High side switches for drivers
