VN920PEP-E Single channel high side driver Features Type RDS(on) IOUT VCC VN920PEP-E 15 m 30 A 36 V • CMOS compatible input • Proportional load current sense • Shorted load protection • Under voltage and overvoltage shutdown • Overvoltage clamp • Thermal shutdown • Current limitation • Protection against loss of ground and loss of VCC • Very low standby power dissipation • Reverse battery protected (see Application schematic on page 17) • In compliance with the 2002/95/ec european directive u d o PowerSSO-24 r P e t e l o Description r P e t e l o s b O ) (s t c u od Table 1. ) s ( ct s b O The VN920PEP-E is a monolithic device designed in STMicroelectronics VIPower™ M0-3 technology, intended for driving any kind of load with one side connected to ground. Active VCC pin voltage clamp protects the device against low energy spikes (see ISO7637 transient compatibility able). 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. Device automatically turns off in case of ground pin disconnection.
