Description

The ISO8200B is a galvanic isolated 8-channel

driver featuring a very low supply current. It

contains 2 independent galvanic isolated voltage

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.
