VN808SR Octal channel high side driver Features Type RDS(on) Iout VCC VN808SR 150mΩ 0.7A 45V ■ VCC/2 compatible input ■ Junction over-temperature protection ■ Case over-temperature protection for thermal independence of the channels ■ Current limitation ■ Shorted load protection ■ Undervoltage shudown ■ Protection against loss of ground ■ Very low stand-by current ■ Compliance to 61000-4-4 IEC test up to 4KV Description The VN808SR is a monolithic device designed in STMicroelectronics VIPower M0-3 technology, intended for driving any kind of load with one side connected to ground. Figure 1. March 2007 PowerSO-36 Active current limitation combined with thermal shutdown and automatic restart, protect the device against overload. In overload condition, channel turns OFF and back ON automatically so as to maintain junction temperature between TTSD and TR. If this condition makes case temperature reach TCSD, overloaded channel is turned OFF and and will restart only when case temperature has decreased down to TCR( see waveform 3 Figure 7 on page 10). Non overloaded channels continue to operate normally. Device automatically turns OFF in case of ground pin disconnection. This device is especially suitable for industrial applications conform to IEC 61131 Block diagram Rev 3 1/16 www.st.com 16 Contents VN808SR Contents 1 Maximum ratings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 2 Electrical characteristics . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4 3 Pin connections . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6 4 Current, voltage conventions and internal diagram . . . . . . . . . . . . . . . 8 5 Switching time waveforms . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 6 Mechanical data . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13 7 Order codes . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15 8 Revision history . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16 2/16 VN808SR 1 Maximum ratings Maximum ratings Table 1.
