Description
The STEVAL-IFP033V1 functions with the
STEVAL-PCC009V2 or STEVAL-PCC009V1
interface board to allow evaluation of the
ISO8200BQ device. A large GND area on the
printed circuit board is included to minimize noise
effects and ensure good thermal performance.
The ISO8200BQ is a galvanic isolated 8 channel
driver featuring a very low supply current. It
contains two independent galvanic isolated
voltage domains (V
CC
for the power stage and
V
DD
for the digital stage). The IC is intended to
drive any type of load with one side connected to
ground. Independent active channel current
limitation combined with thermal shutdown for
each channel and automatic restart protect the
device against overload. Other embedded
functions include loss of GND protection which
automatically turns off the outputs in case of
analog ground, undervoltage shutdown with
hysteresis and a reset function for immediate
power output shutdown.
Built-in thermal shutdown protects the chip
against overtemperature and short-circuit. The
channel is turned off in the overload condition
and switched back on automatically once the IC
temperature decreases below the reset
threshold. If this condition causes the case
temperature to reach the TCR limit, the
overloaded channel is turned off and will only
restart when case and junction temperature
decreased down to the reset threshold. Non
overloaded channels continue to operate
normally.
An internal circuit provides an OR-wired non
latched common FAULT indicator signaling
channel OVT. The FAULT pin is an open-drain
active-low fault indication pin.
