STEVAL-IFP015V2 STMicroelectronics

STEVAL-IFP015V2 Galvanically-isolated 8 channel high-side driver based on the ISO8200B Data brief PCC009V2 or STEVAL-PCC009V1 interface board to allow evaluation of all the features of the ISO8200B device. A large GND area on the printed circuit board has been designed to minimize noise effects and ensure good thermal performance. The ISO8200B is a galvanic isolated 8 channel driver featuring a very low supply current. It contains 2 independent galvanic isolated voltage domains (V for the power stage and V for the CC DD digital stage). The IC is intended to drive any type 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. Additional embedded functions are: loss of GND protection which automatically turns off the outputs in case of analog ground, undervoltage shutdown with hysteresis, and reset Features function for immediate power output shutdown. V operating voltage from 10.5 to 33 V CC Built-in thermal shutdown protects the chip 0.7 A for each channel against overtemperature and short-circuit. In Reverse polarity protection on V and V CC DD overload condition, the channel turns off, then supply voltage back on automatically after the IC temperature Digital supply voltage V 3.3/5 V DD has decreased below a reset threshold. If this Microcontroller interface direct/synchronous condition causes the case temperature to reach mode communication the TCR limit, the overloaded channel is turned Designed to meet requirements of IEC off and will restart only when case and junction 61000-4-2, IEC 61000-4-4, IEC 61000-4-5 temperature have decreased down to the reset standards threshold. Non overloaded channels continue to RoHS compliant operate normally. An internal circuit provides an OR-wired non Description latched common FAULT indicator signaling The STEVAL-IFP015V2 demonstration board channel OVT. The FAULT pin is an open-drain works in combination with the STEVAL- active-low fault indication pin.
