AMIS-39101 ASSP from AMI Semiconductor

AMI Semiconductor has expanded its family of high-side driver ASSPs with a device designed to control LEDs, relays, solenoids, transistor gates, valves and other loads in industrial systems.

The AMIS-39101 ASSP is qualified for operation up to 28V and suited for designs with nominal system supply voltages of 24V. In an SO28 package, the AMIS-39101 integrates eight high-side (HS) output drivers and a range of functions designed to reduce component count and cost.

Built-in functions include an SPI for direct connection to an MCU, an integrated diagnostic circuit and short circuit and thermal overload protection.

Each of its HS drivers will drive a continuous current of 275mA when connected to an inductive load of 300mH. Higher individual output currents are possible by limiting device current to the total maximum.

The drivers will withstand short circuits to the power supply or to ground, respectively, even in situations in which the device has lost its ground connection.

The AMIS-39101 ASSP incorporates a power down mode to reduce power consumption during non-active periods and uses an integrated slope control function that ensures low electromagnetic emission. Operating temperature is rated at -40C to 80C.

The AMIS-39101 is available today for $2.07 each in 1,000-piece quantities.
