BTM7700G 4 Circuit Description 4.1 Input Circuit The control inputs IH1,2 consist of TTL/CMOS compatible Schmitt-Triggers with hysteresis. Buffer amplifiers are driven by these stages and convert the logic signal into the necessary form for driving the power output stages. The inputs are protected by ESD clamp-diodes. The inputs IL1 and IL2 are connected to the gates of the standard N-channel vertical power-MOS-FETs. 4.2 Output Stages The output stages consist of an low RDSON Power-MOS H-bridge.
