Pocatello, IdahoAMI 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 28-V and suited to designs with nominal system supply voltages of 24-V. 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 a serial-to-parallel interface (SPI) for direct connection to a microcontroller, an integrated diagnostic circuit and short circuit and thermal overload protection.
Each of its HS drivers will drive a continuous current of 275-mA when connected to an inductive load of 300-mH. 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 (EME). Operating temperature is rated at -40°C to 80°C.
The AMIS-39101 is available now for $2.07 each in 1000-piece quantities.
