FUNCTIONAL BLOCK DIAGRAM
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 is
designed for use with an external N-channel
MOSFET which are readily available in a wide
variety of voltages.
