above the positive supply to 33V below it. These operat-
ing voltages are limited by internal diode clamps shown
in Figures 1 and 2. On supplies less than 35.5V, the lower
range is limited by V– + 2.5V. This allows the monitored
supply, VBATT, to be separate from the LT6109 positive
supply as shown in Figure 7. Figure 8 shows the range of
operating voltages for the SENSELO and SENSEHI inputs,
for different supply voltage inputs (V+). The SENSELO and
SENSEHI range has been designed to allow the LT6109 to
monitor its own supply current (in addition to the load),
as long as VSENSE is less than 200mV. This is shown in
Figure 9.
Minimum Output Voltage
The output of the LT6109 current sense amplifier can
produce a non-zero output voltage when the sense voltage
is zero. This is a result of the sense amplifier VOS being
forced across RIN as discussed in the Output Voltage Er-
ror,
VOUT(VOS) section. Figure 10 shows the effect of the
input offset voltage on the transfer function for parts at
the VOS limits. With a negative offset voltage, zero input
sense voltage produces an output voltage. With a positive
offset voltage, the output voltage is zero until the input
sense voltage exceeds the input offset voltage. Neglect-
ing VOS, the output circuit is not limited by saturation of
pull-down circuitry and can reach 0V.
Response Time
The LT6109 amplifier is designed to exhibit fast response
to inputs for the purpose of circuit protection or current
monitoring. This response time will be affected by the
external components in two ways, delay and speed.
