Product overview
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.
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 TCR limit threshold, the overloaded channel is turned off and it only restarts when case and junction temperature decrease down to the reset thresholds. Non-overloaded channels continue operating 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.
