摘要： A semiconductor device (10) is described herein. The semiconductor device includes a semiconductor chip having a load current path operable to carry - in accordance with an input signal (IN 1 ) - a load current (i L ) from a supply terminal (SUP) having a supply voltage (V S ) to an output circuit node (OUT 1 ). The device further includes a voltage comparator (16) that is configured to compare the supply voltage with a voltage threshold (V LV ) and to signal (LV) a low supply voltage when the supply voltage reaches or falls below the voltage threshold. An over-current detector (15) is configured to compare a load current signal (S C ) that represents the load current with an over-current threshold (S TH ) and to signal (S OC ) an over-current when the load current signal reaches or exceeds the over-current threshold. Furthermore, the semiconductor device includes a control logic unit (12) that is configured to deactivate the load current flow when an over-current is signalled and to reduce the over-current threshold from a first value (S HI ) to a lower second value (S LO ) as long as the voltage comparator (16) signals (LV) a low supply voltage.

摘要： Provided is a power-supply control device that uses an IPD with self-protection functionality, the IPD reducing heat generation and loss when compared with an electromagnetic relay, and that is operable even at a power source voltage equal to or below an operating voltage. A power-supply control device includes a transistor 7 that is interposed between a power source 6 and a load 2 as well as a control circuit 8 to which a voltage from the power source 6 is applied, the voltage being applied across a high-voltage side input terminal and a low-voltage side input terminal of the control circuit 8, and which turns the transistor 7 on or off based on an operating signal for the load 2 that is applied from an external device, and the power-supply control device controls supply of power to the load 2. The power-supply control device includes a voltage detector 4 that detects the value of the voltage applied to the control circuit 8 by the power source 6, a determination means (4) that determines whether or not the applied voltage value detected by the voltage detector 4 is lower than a predetermined voltage value, and a negative voltage output circuit 5 that outputs a negative voltage to the low-voltage side input terminal of the control circuit 8 if the determination means (4) determines that the applied voltage value is lower than the predetermined voltage value.

摘要： Es wird ein aus einem Akkumulator gespestes und mit einem Tastschalter ein- und ausschaltbares elektronisches Gerät beschrieben, das nach einem kurzzeitigen Ausfall der Akkumulatorspannung (U A ) ohne Betätigung einer Schalttaste sofort wieder betriebsbereit ist. Das elektronische Gerät weist einen ersten Tastschalter (10) auf, der bei kurzzeitiger Betätigung einen von der Akkumulatorspannung gespeisten Ladestromkreis für einen Kondensator (22) schließt. Sobald der Kondensator zumindest teilweise aufgeladen ist, löst die Kondensatorspannung die Erregung eines Relais (32) aus. Bei erregtem Relais wird ein von dem Relais gesteuerter Schalter (34) geschlossen, der eine Verbindung zwischen dem Akkumulator und einem Speisespannungsanschluß (35) für die elektrische Schaltung (36) des elektronischen Gerätes herstellt. Beim Loslassen des ersten Tastschalters (10) kommt ein Haltestromkreis (31,12,13) für das Relais zur Wirkung. Ein zweiter Tastschalter (30) bildet einen Ausschalter. Bei Betätigung dieses Tastschalters wird ein den Kondensator (22) entladender Stromkreis geschlossen. Dadurch wird das Relais (32) stromlos gemacht und der Schalter (34) geöffnet, so daß die Speisespannung für die elektrische Schaltung (36) abgeschaltet ist. (Figur)

摘要： A control apparatus has a momentary switch. In response to an operation performed on a momentary switch, a latch circuit (13) switches a latch output signal to be outputted to a microcomputer (11) from "high" to "low" and keeps the latch output signal "low". A capacitor (C) supplies an electric power to the latch circuit (13) when supply of the electric power is cut off. A reset circuit (15) sends a signal to the latch circuit (13) in response to an input of a high-level latch reset signal from the microcomputer (11) so that the latch circuit (13) switches the latch output signal from "low" to "high". If the latch output signal is "high" when the microcomputer (11) detects that the switch (SW) is operated, a transistor (Tr) is turned on under the control of the microcomputer (11). If the latch output signal is "low" when the microcomputer (11) detects that the switch (SW) is operated, the transistor (Tr) is turned off under the control of the microcomputer (11). The microcomputer (11) outputs the high-level latch reset signal to the reset circuit.

摘要： A method of powering up a circuit includes powering up a latch circuit (104) in a known latch state by applying a first power supply voltage differential of a first voltage domain (VDDO) across power supply terminals of the latch circuit. A current diode (152 146) inhibits current diode in a current path between a latch node (RST, RSTb) of the latch circuit and a power supply terminal when the power supply voltage differential is below a threshold voltage during the powering up in which the inhibiting prevents the latch circuit from switching from the known latch state during the powering up.
