The present invention refers to a control unit (1) for a battery system for controlling a power switch, comprising: a microcontroller (10) configured to generate a first control signal (12); a monitoring unit (20) configured to detect an operational state of the microcontroller (10) and configured to generate a fault signal (22) indicative of the operational state of the microcontroller; a first signal source (30) configured to generate a state signal (31) indicative of a system state; a comparator circuit (40) configured to receive the first control signal (12) and the fault signal (22) and configured to generate an intermediate control signal (41) based on the first control signal (12) and the fault signal (22); the comparator circuit (40) comprising a comparator node (n0), the comparator circuit (40) configured to transmit the intermediate control signal (41) to the comparator node (n0); wherein the first signal source (30) is further connected to the comparator node (n0) to transmit the state signal (31) to the comparator node (n0); the comparator circuit (40) further comprises a comparator (50) connected to the comparator node (n0) and configured to generate a switch control signal (43) based on a voltage on the comparator node (n0) and based on a threshold voltage (Vth).
