Description
General part information
STEVAL-IFP019V1 Series
The VNI414K (for loads up to 0.6 A) and VNI4140K-32 (for loads up to 1.0 A) are monolithic 4-channel drivers featuring very low RDS(on) and per-channel diagnostic. The ICs, realized in STMicroelectronics™ VIPower™ technology, are 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.
A channel in an overload condition overheats and turns OFF and back ON automatically in order to maintain its junction temperature between TTSD and TR. If this condition makes case temperature reach TCSD, the overloaded channel is turned OFF and restarts only when case temperature has decreased down to TCR. In case of more than one channel in overload, restart of the overloaded channels is not simultaneous, in order to avoid high peak current from the supply. Non-overloaded (non-overheated) channels continue operating normally.
