AMIS-39100
Octal High Side Driver with
Protection
General Description
The AMIS39100 is a general purpose IC with eight integrated high
side (HS) output drivers. The device is designed to control the power
of virtually any type of load in a 12 V automotive environment, such
as transistor gates, relays, LEDs etc.
Each of the output drivers of the AMIS39100 is able to drive up to
275 mA continuously when connected to an inductive load of
300 mH. Even higher driver output currents can be obtained as long as
the total current of the device is limited. The integrated chargepump
of the AMIS39100, which uses only one low cost external capacitor,
avoids thermal runaways even if the battery voltage is low. The HS
drivers withstand short to ground (even when AMIS39100 has lost its
ground connection), short to the battery and has overcurrent
limitation. In case of a potential hazardous situation, the drivers are
switched off and the diagnostic state of the HS drivers can be read out
via serial peripheral interface (SPI). In case of a short to ground, the
output driver is deactivated after a debounce time.
The AMIS39100 can be connected to a 3.3 V or 5 V
microcontroller by means of a SPI interface. This SPI interface is used
to control each of the output drivers individually (on or off) and to read
the status of each individual output driver (readback of possible error
conditions). This allows the detection of error situations for each
driver individually. Furthermore, the SPI interface can be used to
readback the status of the builtin thermal shutdown protection. The
AMIS39100 has a lowpower mode and excellent handling and
system ESD characteristics.
