STMicroelectronics IPS4140HQ Quad High-Side Solid State Relays
STMicroelectronics IPS4140HQ Quad High-Side Smart Power Solid State Relays are monolithic 4-channel drivers with very low RDS(on) and per-channel diagnostics. The ICs, realized in STMicroelectronics VIPower™ technology, are intended to drive any load with one side connected to ground. Active channel current limitation combined with independent protection for each channel, thermal shutdown, and automatic restart protects the device against overload.
A channel in an overload condition overheats and turns OFF and back ON automatically to maintain its junction temperature between TTSD and TR. If this condition causes the case temperature to reach TCSD, the overloaded channel is turned OFF and restarts only when the case temperature has decreased to TCR. In the case of more than one channel in overload, restarting the overloaded channels is not simultaneous to avoid high peak current from the supply. Non-overloaded (non-overheated) channels continue operating normally.
The four open drain STATUSX output pins indicate per-channel overtemperature conditions.
