System Power Supply Circuit Protection
5.3.4.1
DC Power System Protection
The recommended DC Power System Protection consists of the following:
A DC Power Supply capable of delivering 7.5V to 21.0V to the mobile module
An Overcurrent Protection circuit providing a means to limit the maximum current available to
the system
A Slew Rate Control circuit providing a controlled voltage slew rate at turn on, which provides
protection for components sensitive to fast voltage rise times
An Undervoltage Lockout circuit that protects against potentially damaging high currents,
which might be encountered if the DC Power Supply voltage is too low
An Overvoltage Lockout circuit providing protection from potentially damaging high DC
Power Supply voltages
Bulk Decoupling Capacitors providing filtering and a reservoir of energy, which can provide a
faster transient response than the power supply
