AMI Semiconductor is launched to control...

AMI Semiconductor has introduced a new device that expands its range of high-end driver ASSP (Special Application Standard Products) designed to control LEDs, relays, solenoids, transistor gates, transistors and other loads in industrial systems Designed for things. The new AMIS-39101 meets the conditions for operation up to 28V and is perfectly matched to the 24V rated system supply voltage. It integrates eight high-end (HS) output drivers in a single SO28 package with a variety of features and features designed to dramatically reduce component count and cost. Its built-in features include a serial-to-parallel conversion interface (SPI) for direct connection to the microcontroller, integrated diagnostic circuitry, and short-circuit and thermal protection circuitry. When connected to a 300mH inductive load, each high-end driver in the new device can generate 275mA of continuous current. Independent output current can be increased by limiting the sum of the device currents to a maximum. Even if it is not grounded, the drive can be short-circuited to the power supply or shorted to ground, respectively. These drivers also provide an overcurrent limit that automatically shuts down when a fault condition occurs. The AMIS-39101 features an overheat protection circuit that protects itself from thermal runaway, even at low supply voltages. The SPI interface is compatible with 3.3V and 5V microcontrollers to control individual independent output drivers and provide a path for integrated diagnostic circuitry to feed back fault signals. This interface can also be used to read the status of the built-in thermal shutdown protection. The AMIS-39101 ASSP features a “power saving” mode that reduces energy consumption during inactivity, while it uses integrated slope control to ensure low electromagnetic emissions (EME). It is rated for operation from -40 ° C to 80 ° C. “Since this new device has been used to drive general industrial loads (from LEDs to relays, transistors and solenoids), it has become a highly integrated, small alternative to discrete solutions,” AMI Semiconductor High Voltage Communications and Toshi Denayer, senior vice president of ASSP business, said, "AMIS-39101 enables engineers to use a single device as a drive circuit for multiple loads at supply voltages up to 24V." AMIS-39101 is available now, priced at: 1,000 The unit price is $2.07.
