Lighting Management Units

Highly integrated, flexible lighting management ICs support nearly all the illumination tasks performed in mobile phones.

Operational Amplifiers

Operational amplifiers from ams are ideally suited to audio applications.

Power Management Units

These highly integrated, flexible power management units are ideal for use in portable, battery-powered devices.

Supervisors

ams supervisors offer high accuracy and low power consumption. In battery-powered systems in particular, the supply must be monitored in order to perform safe start-up and shut-down operations.
