Surge Stopper with Ideal Diode Protects Input and Output
Zhizhong Hou Power systems in automobile and industrial applications must cope with short duration
high voltage surges, maintaining regulation at the load, while protecting sensitive
circuitry from dangerous transients. One common protection scheme involves a series
iron core inductor and high value electrolytic bypass capacitor, augmented by a high
power transient voltage suppressor (TVS) and fuse. This heavy-handed approach takes
significant board real estateвЂ”the bulky inductor and capacitor are often the tallest
components in the system. Even this protection scheme cannot protect against reverse
input potentials or supply brownoutsвЂ”possible scenarios in automotive environments.
To protect against these events and maintain the output voltage, designers add a
blocking diode, but the additional voltage drop in the diode increases power losses.
The LTC4364 is a complete control solution
for load protection and output holdup in a
small footprint, eliminating bulky components and undesirable voltage drops.
Figure 1 shows a functional block diagram of the LTC4364. The part drives two
back-to-back N-channel pass transistors:
one protects against voltage surges and
maintains a regulated voltage to the output (M1 in Figure 1), while the other acts
as an ideal diode for reverse input protection and output holdup (M2 in Figure 1).
The LTC4364 also guards against overloads
and short circuits, withstands output
voltage reversal, holds off the MOSFETs in
input undervoltage conditions and inhibits …
