AMIS-39101
Octal High Side Driver with
Protection
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 350 mA 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 interface 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 serial 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.
