Low VCEsat (BISS) load switches

Building on the success of our energy-saving BISS transistor technology, our BISS load switches combine low V_CEsat (BISS) transistors with resistor-equipped transistors (RETs) to deliver load switch functionality from a single package.

These ultra-low-loss devices help reduce component count and total system cost while cutting board space requirements by more than 45%.

Key features

• Low V_CEsat (BISS) transistor and resistor-equipped transistor (RET) in one package
• Low saturation voltage
• Low 'threshold' voltage (<1V) compared to MOSFET
• Low drive power required
• Range of small, very small and ultra-small packages

Key benefits

• Smaller end products
• Reduced component count
  
  • Less sourcing effort
  • Fewer solder points increases reliability
  • Potential for cost reduction
• More-efficient, cooler-running systems

Key applications

• Supply line switch
• Battery charge switch
• High-side switch for LEDs, drives and backlights
• Portable equipment
