VN920B5TR-E

VN920B5-E Single channel high-side solid state relay Features Type RDS(on) IOUT VCC VN920B5-E 16 mΩ 30 A 36 V ■ ECOPACK®: lead free and RoHS compliant ■ Automotive Grade: compliance with AEC Guidelines ■ Very low standby current ■ CMOS compatible input ■ Proportional load current sense ■ Current sense disable ■ Thermal shutdown protection and diagnosis ■ Undervoltage shutdown ■ Overvoltage clamp ■ Load current limitation P2PAK Description The VN920B5-E is a monolithic device designed in STMicroelectronics™ VIPower™ M0-3 technology. The VN920B5-E is intended for driving any type of load with one side connected to ground. The active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility table). Active current limitation combined with thermal shutdown and automatic restart protect the device against overload. The device integrates an analog current sense output which delivers a current proportional to the load current. The device automatically turns off in the case where the ground pin becomes disconnected. Table 1.
