The present invention refers to a solid state switch, SSS, driver circuit (100) for controlling a solid state switch (150) that is operated as high side switch between a battery cell stack and a load. The SSS driver circuit (100) comprises a voltage generation circuit (10), a switch off circuit (30) and a switch controller (50). Therein, the voltage generation circuit (10) is configured for receiving an supply voltage, VSUP, via a first input node (11), an output voltage of the battery cell stack, GNDdriver, via a second input node (12), a ground voltage, GND, via a first ground node (13) and a first control signal, PWM. The voltage generation circuit (10) is further configured for generating a drive voltage, VCCDriver, higher than VSUPand GNDdriverin dependence of the first control signal and for outputting VCCDriverto a first output node (15). The switch off circuit (30) is configured for receiving sthe output voltage GNDdrivervia a third input node (31), a ground voltage, GND, via a second ground node (33), a second control signal, OFF1, and a third control signal, OFF2, and is further configured for outputting, GNDDriver, to a second output node (35) in dependence of the second and third control signals. The switch controller (50) is connected to the first output node (15) and to the second output node (35) and is configured for receiving a ground voltage, GND, via a third ground node (53) and a fourth control signal, ON1. The switch controller (50) is further configured for connecting the first output node (15) and a gate node (151) of the solid state switch (150) in dependence of the fourth control signal. The invention further relates to a battery system (200) comprising the SSS driver circuit (100) of the invention.
