摘要： An electronic device (102) includes a power supply (114), an amplifier circuit (132), and a power down protection circuit (160). The power supply (114) supplies power to the electronic device (102). The amplifier circuit (132) is powered by the power supply (114) to amplify a signal into an amplified output signal and controllable to vary a power level of the amplified output signal. The power down protection circuit (160) is coupled directly to the power supply (114) to lower the power level of the amplified output signal of the amplifier circuit (132) when the power supply (114) falls below a threshold.

摘要： A safety system for electronic devices having multiple power inputs includes dedicating a different power detector to each power input and includes disabling all of the power inputs upon detection that one input has been disabled. Each of the power inputs is typically a power cord that provides electrical energy to a discrete electrical circuit. Thus, the safety system permits the electronic device to use a different power supply for each electrical circuit, while ensuring that there is no erroneous assumption that disconnecting one of the power cords will de-energize the entire electronic device. In the preferred embodiment, the paths to the power supplies are disabled by opening relay switches, with the switches that are specific to a power cord being in a logical AND arrangement.

摘要： An automatic safety switch provides an automotive battery with protection against accidental discharge due to operator neglect. Such operator neglect includes inadvertent use of electrical circuits such as headlights, parking lights, or interior lights subsequently to turning the ignition off. This invention is connected in series with at least one of the power cables connecting the battery to the fuse box of a vehicle. The choice of power cable is made based on where the circuits to be protected are connected inside the fuse box itself. The automatic safety switch is connected as close to the fuse box as possible, since all necessary connection points are available in the immediate vicinity of the fuse box. The automatic safety switch comprises circuitry that impedes a current flow to its protected output loads when the battery voltage has diminished to a minimum voltage that can safely start a vehicle. The automatic safety switch remains in its current impeded state until reset by the ignition switch. The ignition switch unconditionally resets the automatic safety switch. The automatic safety switch further comprises safety features that prevents it from turning off during reset, even if the battery voltage would diminish to an extremely low voltage. A timer further protects against battery discharge from small electrical loads such as the automatic safety switch itself.
摘要翻译：自动安全开关提供汽车电池，防止由于操作员疏忽而意外卸载。这样的操作者忽略包括随后将点火开关关闭，无意中使用诸如前大灯，停车灯或室内灯之类的电路。本发明与将电池连接到车辆的保险丝盒的至少一个电力电缆串联连接。电源电缆的选择是基于保险丝盒本身连接到被保护电路的位置。自动安全开关尽可能靠近保险丝盒连接，因为所有必要的连接点在保险丝盒的紧邻附近可用。自动安全开关包括当电池电压已经降低到可以安全地启动车辆的最小电压时阻止电流流向其受保护的输出负载的电路。自动安全开关保持在电流阻碍状态，直到点火开关复位为止。点火开关无条件复位自动安全开关。自动安全开关还包括安全功能，即使电池电压降低到极低的电压，也可防止在复位期间关闭电源。定时器进一步防止诸如自动安全开关本身的小电气负载的电池放电。

摘要： An on-chip voltage regulator circuit isolates the chip circuitry from spurious signals and electrostatic discharge (ESD) of peripheral circuitry. A bypass function for the regulator circuit is initiated on detection of the onset of an over voltage condition. In one implementation, a MOSFET is used to (1) initiate a parallel current path from Vcc to Vdd and (2) bypass the regulator to establish a continuous current path from the ESD diode to the Vcc to the Vdd power grid. The circuit addresses level shifting and uses an RC triggering technique.

摘要： A fuse blown detection circuit for use in conjunction with the control transistor output circuits of a programmable controller which provides low leakage after the fuse is blown. The detection circuit comprises a pair of voltage dividers and a diagnostic triggering device forming an H-bridge network connected across the terminals of the fuse and a blocking diode. When the fuse is blown the voltage levels defined by the dividers change to activate the trigger device and enable a diagnostic signal indicative of the fuse blown condition while the blocking diode prevents current flow back through the control transistor and output circuit.
