Infineon – OPTIREG™ TLT807B0EPV – adjustable voltage regulator
Trucks as well as commercial, construction and agricultural vehicles have 24V battery operated systems instead of the usual 12V battery in cars. The different voltage requirements lead to a load dump voltage for the latter which is typically higher and could go up to 58V. In addition to higher load dump voltages, another important requirement to consider is the lifetime requirements of trucks and commercial agricultural vehicles. A car on average has a lifetime of about 300kkm where as heavy duty trucks can have lifetimes of 800kkm up to 1000kkm. This makes the ‘lifetime’ requirements for these vehicles three times as much as those for cars.
With the new TLT807B0EPV, not only takes into consideration the load dump requirements, but also that the lifetime requirements for the intended application by means of extended qualifications. A choice of a robust package in addition to the above mentioned criteria make the TLT807 the first linear voltage regulator specifically designed for trucks and commercial agricultural vehicles!
