The VNI4140KTR (for loads up to 0.6 A) and VNI4140K-32 (for loads up to 1.0 A) are monolithic 4-channel drivers with very low RDS(on) and per-channel diagnostics. Implemented using STMicroelectronics™ VIPower™ technology, these ICs are designed to drive any kind of load that is grounded on one side.

The VNI4140KTR active channel current limit combined with thermal shutdown, independent of each channel, and automatic restart to prevent device overload.

A channel under VNI4140KTR overload condition overheats and automatically turns off and back on to maintain the junction temperature between its TTSD and TR. If this condition causes the case temperature to reach TCSD, the overload channel will shut down and only restart when the case temperature drops to TCR. In the event of multiple channel overloads, the restart of the overloaded channels is not done simultaneously to avoid high peak currents from the power supply. Non-overloaded (non-overheated) channels continue to operate normally.
