Octal High-Side Driver includes built-in protection systems.
Press Release Summary:
Monolithic Model VN808 drives any load that has one side connected to ground. It handles 0.7 A with 45 V supply and offers RDS(ON) of 150 mohms. Part is equipped with active current limiter, thermal shutdown, and automatic restart circuits, as well as protection against shorted loads and under-voltage conditions. Provided in PowerSO-36 package, driver is suited for applications that must conform to IEC 1131 standard for programmable controllers.
Original Press Release:
Octal High-Side Driver from STMicroelectronics Drives and Protects
Multiple protection strategies are built in
Geneva, December 7, 2004 - STMicroelectronics (NYSE: STM) has launched an octal high-side driver with built-in protection systems and diagnostics for use in automation and industrial process control.
The VN808 is a monolithic device designed to drive any load that has one side connected to ground. It handles 0.7A with a 45V supply and offers an RDS(ON) of 150m ohms. The part works with VCC/2 inputs.
The VN808 has been equipped with various protection mechanisms. It has an active current limiter, thermal shutdown and automatic restart circuits. If the part becomes overloaded, one channel turns off and back on automatically to maintain the junction temperature between its shutdown temperature and its reset temperature. If this condition makes the case temperature reach its shutdown limit, the overloaded channel is turned off and will restart only when the case temperature has fallen to the case reset temperature. Channels that have not been overloaded will continue to work normally.
The driver turns off if the ground pin is disconnected. Other built-in safety mechanisms include protection against shorted loads and under-voltage conditions. The part also has a very low stand-by current requirement.
The VN808 is especially suitable for industrial applications that must conform to the IEC 1131 international standard for programmable controllers.
It is offered in a PowerSO-36 package. Pricing is US$3.50 in quantities of 10K pieces.
