3 Description
The TPS2400 overvoltage protection controller is
used with an external N-channel MOSFET to isolate
sensitive electronics from destructive voltage spikes
and surges. It is specifically designed to prevent large
voltage transients associated with automotive
environments (load dump) from damaging sensitive
circuitry. When potentially damaging voltage levels
are detected by the TPS2400 the supply is
disconnected from the load before any damage can
occur.
Internal circuitry includes a trimmed band-gap
reference, oscillator, Zener diode, charge pump,
comparator, and control logic. The TPS2400 device is
designed for use with an external N-channel
MOSFET, which are readily available in a wide
variety of voltages.
