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.
