The L9680TR device is a chip that can be used in the mature airbag market. The device enables safety system integration through higher supply current and a drive wheel speed sensor interface.
The operating frequency of the switching regulator is in the range of 1.882MHz. Buck converters integrate synchronous rectifiers.
The backup capacitor is galvanically isolated from the boost regulator using a 65 mA rated current source. And can effectively control the surge.
Because the quiescent current of the L9680TR device is small, it can be connected directly to the battery. In this way, the turn-on and turn-off of the L9680TR device is controlled by the wake-up input function.
