APPLICATION INFORMATION

Typical application setup is shown below.

Microcontroller is controlling MAS9118 using DIN,

CCLK and XCS. The microcontroller power supply is

regulated voltage, which is lower than the battery

voltage.

MAS9118 output drivers are directly connected to the

battery voltage.The buzzer or loudspeaker can be

directly connected between MAS9118 positive

(OUTP) and negative (OUTN) outputs. The MAS9118

chip will automatically connect these outputs to VSS

when chip is at power-down mode.
