SIPMOS transistor push pull control circuit

Published:2011/4/26 2:56:00 Author:May | Keyword: SIPMOS transistor, push pull control | From:SeekIC

Input end of this circuit is connected integrated circuit TDA4700. When its output transistor turns on, base of T1 has voltage which is determined by R1, R2. Diode D1 and D2 is used to prevent the over saturation of T1. If output transistor of TDA4700 is cut off, T1 is cut off, T2 is controlled by R4, at this time, SIPMOS transistor input capacitor (crossover in the justified of R5 and T2) is as limiting resistor. The current consume of this circuit is very small because it adopts push pull control mode.
