Product overview
Description
The ISO8200BQ 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).
The IC is intended to drive any kind of load with one side connected to ground. Active channel current limitation (OVL) combined with thermal shutdown (OVT) and automatic restart (independent for each channel) , protects the device against overload and short-circuit.
Built-in thermal shutdown protects each channel from over-temperature and overload: each overheated channel automatically turns OFF after its junction temperature triggers the protection threshold (TJSD). The channel turns back ON if its junction temperature decreases lower than restart threshold (TJR).
An additional case temperature sensor protects the whole chip against over-temperature (OVC event): if the case temperature triggers the TCSD threshold then overloaded channels are turned OFF and restart only when case temperature decreased down to the reset threshold (TCR). Non overloaded channels continue to operate normally.
Other embedded functions are loss of ground protection, VCC and VDD UVLOs (with hysteresis), reset function for immediate power output shutdown and watchdog.
An internal circuit provides an OR-wired not latched OVT that is reported on the common FAULT indicator pin. FAULT is an open drain, active low, fault indication pin.
The Synchronous Control Mode (by driving SYNC and LOAD pins independently) is used to reduce the jittering of the outputs and to drive at the same time the outputs of different devices.
