Description
The ISO8200B is a galvanic isolated 8-channel
driver featuring a very low supply current. It
contains 2 independent galvanic isolated voltage
domains (Vcc for the power stage and Vdd for the
digital stage). Additional embedded functions are:
loss of GND protection, undervoltage shutdown
with hysteresis, and reset function for immediate
power output shutdown.

The IC is intended to drive any kind of load with
one side connected to ground. Active channel
current limitation combined with thermal
shutdown, (independent for each channel), and
automatic restart, protect the device against
overload and short-circuit. In overload conditions,
if junction temperature overtakes threshold, the
channel involved is turned off and on again
automatically after the IC temperature decreases
below a reset threshold. If this condition causes
case temperature to reach the limit threshold
TCR, the overloaded channel is turned off and
only restarts when case and junction temperature
decrease down to the reset thresholds. Non-
overloaded channels continue to operate
normally. An internal circuit provides an OR-wired
non latched common FAULT indicator signaling
the channel OVT. The FAULT pin is an open drain
active low fault indication pin.
