摘要： A fail-safe timer circuit which does not generate such an erroneous output that shortens delay time when a fault occurs and an on-delay circuit. The timer circuit comprises an oscillator circuit (11) which generates a timer output from the cathode terminal of a PUT prescribed period after an input signal (VIN) is received and a monitoring circuit (12) which monitors the operation of the oscillator circuit (11). The on-delay circuit comprises a latch (13) which has a first terminal (a) for receiving the input signal (VIN) and a second terminal (b) for receiving an output signal (VO) that the monitoring circuit produces only when it is confirmed that the oscillator circuit (11) is normal by detecting a fall of a cathode terminal voltage of the circuit (11). The latch generates an output signal only when both the input signals are higher in level than the power supply potential, and maintains the state.

摘要： A gate drive unit includes a charging device, a switch, and a timing module. The charging device is conductively coupled with an electrical energy source and a power switch between the electric energy source and the charging device. The switch closes to transfer electrical energy from the energy source to the charging device. The timing module is configured to close the switch to direct the electrical energy from the electrical energy source to the charging device for a designated charging time period in order to charge the charging device with the electrical energy while the power switch is in an OFF state. The timing module opens the switch to cause the electrical energy stored in the charging device to be transferred out of the charging device in the form of a trigger current that is conducted to a gate terminal of the power switch to activate the power switch to an ON state from the OFF state.
