VNI4140KTR STMicroelectronics

VNI4140K Quad high-side smart power solid-state relay Datasheet - production data Open drain diagnostic outputs 3.3 V CMOS/TTL compatible inputs Fast demagnetization of inductive loads Conforms to IEC 61131-2 PowerSSO-24 ESD according to IEC 61000-4-2 up to +/- 25 kV Description Features The VNI4140K is a monolithic device made using (1) (1) (1) Type V R I V STMicroelectronics VIPower technology, intended demag DS(on) out CC to drive four independent resistive or inductive VNI4140K V -41 V 0.08 0.7 A 41 V CC loads with one side connected to ground. Active 1. Per channel. current limitation avoids dropping the system power supply in case of shorted load. Built-in thermal shutdown protects the chip from Output current: 0.7 A per channel overtemperature and short-circuit. In overload Shorted load protections conditions, channel turns OFF and back ON automatically so to maintain junction temperature Junction overtemperature protection between T and T . If this condition makes TSD R Case overtemperature protection for thermal case temperature reach T , overloaded CSD independence of the channels channel is turned OFF and restart only when case Thermal case shutdown restart not temperature has decreased down to T . In case CR simultaneous for the various channels of more than one channel in overload, restart of the overloaded channels is not simultaneous, in Protection against loss of ground order to avoid high peak current from the supply. Current limitation Non-overloaded channels continue operating Undervoltage shutdown normally. The open drain diagnostics outputs indicate overtemperature conditions. Figure 1.
