(DE19706946-A1)      The monitor includes a power semiconductor circuit breaker which is connected into a battery feed line. The feed line includes a power FET group (11) and an associated sensing FET group (13).    Circuitry coupled to the sensing FET enables current flowing in either direction to be monitored by resistors (R1,R2). The power FET group forms the circuit-breaker which can provide short circuit protection or prevent unauthorised use.    ADVANTAGE -   Provides the possibility of switching off the battery current. Provides bidirectional current sensing to enable charge monitoring for the battery.
