AMIS-39101: Octal High-Side Driver with Protection Data Sheet 1.0 General Description The AMIS-39101 is a robust high-side driver IC featuring eight independent high current output drive channels along with a number of integrated fault-protection circuits. This highly integrated product is designed for controlled delivery of power to a large variety of loads in industrial applications including motors, relays and LED arrays, among others. With all driver output channels in the conducting state, each channel can source up to 350mA of continuous current (resistive load). In cases where all output drivers are not active, higher output current per channel can be achieved provided that the thermal limits of the device are not exceeded. Furthermore, in order to minimize system cost each output driver has built-in fly-back diodes. The device withstands short-circuits to ground and supply, respectively. It is designed with an array of integrated protection features including over-temperature and over-current detection and shut down. The integrated charge pump requires only one external capacitor and provides for operation of the critical fault-protection circuitry even in case of low supply voltages. The device can be interfaced to a variety of microcontrollers via the serial peripheral interface (SPI) link, in turn allowing for monitoring and controlling the state of each of the output drivers individually. In this case, at the onset of a potential hazardous situation the drivers are switched off and the diagnostic state of the drivers can be extracted via the SPI interface. The device also features a power down mode for reduced power consumption and has high built-in electrostatic discharge (ESD) protection capability for robust operation. 2.0 Key Features • • • • • • • • • • • • Eight high-side output drivers Up to 830mA continuous current per driver pair (resistive load) Charge pump with one external capacitor SPI Short-circuit protection Diagnostic features Power-down mode Internal thermal shutdown 3.3V and 5V microcontroller compliant Excellent system ESD Automotive compliant SO28 package with low Rthja 3.0 Typical Applications • • • • • Actuator control LED drivers Relays and solenoids Industrial process control Automotive load management 4.0 Ordering Information Product Name AMIS39101AGA Package PSOP 300-28 (JEDEC MS-013) Temperature Range -40°C…85°C AMI Semiconductor – November 06 - M-20638-001 www.amis.com 1 http://www.Datasheet4U.com AMIS-39101: Octal High-Side Driver with Protection Data Sheet 5.0 Block Diagram Figure 1: Block Diagram AMI Semiconductor – November 06 - M-20638-001 www.amis.com 2 AMIS-39101: Octal High-Side Driver with Protection 6.0 Typical Application Diagram Data Sheet Figure 2: Typical Application Diagram 6.1 External Components It is important to properly decouple the power supplies of the chip with external capacitors that have good high frequency properties.
