摘要: In an amplifier device, a negative output voltage (−) of a differential amplifier stage corresponding to an input signal voltage (Vin) is supplied to the gate of Output transistor M25 for charging electrical charges to Capacitive load (80). A current corresponding to a positive output voltage (+) of the differential amplifier stage is supplied to Node (A) through which the gate of Output transistor M26 for discharging electrical charges from Capacitive load (80) is connected to Constant current source (4). This current becomes a value (Iy+&Dgr;I) according to the voltage (Vin). By changing the gate voltage of Output transistor M26, it enters ON, and the electrical charges are discharged as a current I3 from Capacitive load (80). The voltage (Vin) is converted to a current by Voltage-current converter (1), and Current-voltage converter (2) then converts this current to a voltage. It is thereby possible to increase the driving ability of Output transistor M26 and to perform a response operation at high speed with low power consumption only by changing the current corresponding to the positive output voltage (+) of the differential pair.

摘要: In an assembled battery system, parallel battery blocks are connected in series. Each of the battery blocks includes battery unit modules connected in parallel, and each of the modules includes a battery unit and a fuse connected in series. The battery block is provided with a common connection line connected to a fuse monitoring module, and MOS-FETs each having a gate, source and drain, wherein the fuse is connected between the gate and source, and the drain is connected to the connection line. The FET is turned on and a voltage is applied to the connection line through the FET from the battery unit, when the fuse is blown out. Thus, the fuse monitoring module can detects the blowout of the fuse, and a control module can turn off a control switch to stop charging/discharging of the assembled battery in accordance with the control signal from the fuse monitoring module.
