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 patent application describes a latch circuit that switches on a second switch based on the voltage increase at the input end of the circuit, controlled by a first switch. Here are the key points explained in bullet form:

  • The first switch is turned on when the voltage at the input end reaches a threshold voltage.
  • The current flows through a first resistor and a second resistor in sequence.
  • The second switch is turned on when the first switch is on.
  • The voltage across the first resistor is the threshold voltage or higher when the second switch is on.
  • A microcomputer provides voltage input to the emitter of the first switch.
  • The collector of the second switch outputs 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.
