Title: Protective circuit for power supply
Inventor: TANAKA MASAKI
IPC: H02H3/087
Filed: 1990-08-28
Abstract: PURPOSE:To prevent heating by providing a short circuit current detecting means for inverting the output of a flip-flop and holding the inverted output when the voltage drop across a short circuit detecting resistor reaches a predetermined level and a base current interrupting means to be driven by the output from the short circuit current detecting means thereby interrupting the current of a control transistor upon occurrence of short circuit. CONSTITUTION:When a load L is short-circuited and an overcurrent I flows through a short circuit detecting resistor R0, a transistor Q5 is turned ON and current flows through resistors R1, R2. A flip-flop FF inverts Q output thereof by the rising of a voltage VG appearing across the resistor R2 and holds the inverted Q output thus turning a transistor Q4 ON. Consequently, base current of a transistor Q3 is bypassed and the transistor Q3 is turned OFF thus interrupting the base current of a control transistor Q1. According to the constitution, the control transistor Q1 is turned OFF perfectly.
