Integrated circuit device e.g. supply-sided/mass-sided driver, for switching electrical loads, has switch configured such that switch is used either in supply-sided configuration or in mass-sided configuration

摘要

The device has a power stage with a MOS power transistor, and a driver circuit for controlling a gate of the MOS power transistor e.g. laterally double diffused MOS transistor. A switch is configured such that the switch is used either in a supply-sided configuration or in a mass-sided configuration. The gate of the power transistor is decoupled by the driver circuit, if the transistor is in a locking state and has a supply-sided configuration. A drain gate voltage is attached to the MOS power transistor.
