This device is a high efficiency boost power supply which converts 12V nominal input to 14V/19V nominal output, plus a linear regulation stage for tone signal transmission. It could repeat the external 22kHz tone input symmetrically or synthesize a 22kHz tone signal upon external on/off control. Pulsing on its EN initials -1V/+0.4V drop correction, makes it suitable for using external surge absorbing devices and for long cable installation.
The SGM41286 is available in Green TDFN-3×3-8L and SOIC-8 (Exposed Pad) packages. It operates over an ambient temperature range of -40℃ to +85℃.
