• Manufacturer Part Number: bts50080a
• Description: Smart High-side Power Switch
• Manufacturer: Infineon Technologies Corporation

The power stage has a defined switching behavior. Defined slew rates as well as edge shaping support PWM’ing
of the load while achieving lowest EMC emission at minimum switching losses.

Switching the device on and off may cause switching losses
losses depend on the supply voltage
shows this dependencies of the switching losses.
