LATCH CIRCUIT AND POWER SUPPLY CONTROL DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18552177 titled 'LATCH CIRCUIT AND POWER SUPPLY CONTROL DEVICE

Simplified Explanation

The abstract describes a patent application for a latch circuit that switches on when the voltage between the input end and control end reaches a threshold voltage. The circuit includes multiple switches and resistors to control the flow of current and voltage levels.

  • The latch circuit switches on when the voltage between the input and control ends reaches a threshold voltage.
  • A first switch is turned on, allowing current to flow through a first resistor and a second resistor in sequence.
  • The current is then input to a second switch and a comparator switch, which are turned on when the first switch is on.
  • The voltage across the first resistor is monitored to ensure it is at the threshold voltage or higher.
  • A microcomputer provides a voltage input to the emitter of the first switch, while the collector of the second switch outputs a voltage to a driving circuit.

Original Abstract Submitted

In a first switch of a latch circuit, when the voltage between an emitter (input end) and a base (control end) has increased to a threshold voltage or more, the first switch is switched from off to on. The current that flows through a first resistor and a second resistor in that order is input to a collector (input end) of a second switch and a comparator switch. The second switch is switched on when the first switch is switched on. When the second switch or the comparator switch (third switch) is on, the voltage across the first resistor is the threshold voltage or more. A voltage is input to the emitter of the first switch from a microcomputer. A voltage is output from the collector of the second switch to a driving circuit.
