Optional External Protection
1.5.1
REVERSE BATTERY PROTECTION
An external reverse-battery-blocking diode should be
used to provide polarity protection (see Figure 1-9).
1.5.2
TRANSIENT VOLTAGE
PROTECTION (LOAD DUMP)
An external 43V transient suppressor (TVS) diode,
between VBB and ground, with a transient protection
resistor (RTP) in series with the battery supply and the
VBB pin protects the device from power transients and
ESD events greater than 43V (see Figure 1-9). The
maximum value for the RTP protection resistor depends
upon two parameters: the minimum voltage the part will
start at, and the impacts of this RTP resistor on the VBB
value, thus on the Bus recessive level and slopes.
This leads to a set of three equations to fullfil.
the minimum battery voltage the user wants.
the maximum error on the recessive level, thus VBB,
since the part uses VBB as the reference value for the
recessive level.
the maximum relative variation the user can accept on
the slope when IREG varies.
Since both Equation 1-1 and Equation 1-2 must be
fulfilled, the maximum allowed value for RTP is thus the
smaller of the two values found when solving
Equation 1-1 and Equation 1-2.
Usually Equation 1-1 gives the higher constraint
(smaller value) for RTP as shown in the following exam-
ple where VBATmin is 8V.
However, the user needs to check that the value found
3 as well.
While this protection is optional, it should be
considered as good engineering practice.
Note 1: IREG less than llim, regulator on
2: After IREG exceeds llim, voltage regulator output will be reduced until
voltage regulator shutdown voltage VSD is reached.
