VNI2140J

The VNI2140J is a monolithic device designed using STMicroelectronics' VIPower technology.

The device drives two independent resistive or inductive loads with one side connected to ground. Active current limitation prevents a drop in system power supply in cases of shorted-load, and built-in thermal shutdown protects the chip from damage due to overtemperature and short-circuit.

In overload conditions, channel turns OFF and ON automatically to maintain the junction temperature between T_TSD and T_R. If the case temperature reaches T_CSD, the overloaded channel is turned OFF and restarts only when case temperature decreases down to T_CR. In order to avoid high-peak current from the supply, when more than one channel is overloaded the T_CSD restart is not simultaneous. Non overloaded channels continue to operate normally. The open-drain diagnostics output indicates overtemperature conditions and open-load in OFF-state.
