The ISL55190 single has a dedicated feedback pin which is
internally connected to the amplifier output and located next
to the inverting input pin. This additional output connection
enables the PC board trace capacitance at the inverting pin
to be minimized.
Current Sense Application Circuit
The schematic in Figure 47 provides an example of utilizing
the ISL55190 high speed performance with the ground
sensing input capability to implement a single-supply, G =1 0
differential low side current sense amplifier. This circuit can
be used to sense currents of either polarity. The reference
voltage applied to V
REF
(+2.5V) defines the amplifier output
0A current sense reference voltage at one half the supply
voltage level (V
S
= +5VDC), and R
SENSE
sets the current
sense gain and full scale values. In this example the current
gain is 10A/V over a maximum current range of slightly less
than ±25A with R
SENSE
= 0.01
Ω
. The amplifier V

error
(-1.1mV max) and input bias offset current (I
IO
) error (1.3μA)
together contribute less than 15mV (150mA) at the output for
better than 0.3% full scale accuracy.
The amplifier’s high slew rate and fast pulse response make
this circuit suitable for low-side current sensing in PWM and
motor control applications. The excellent input overload
recovery response enables the circuit to maintain
performance in the presence of parasitic inductance that can
cause fast rise and falling edge spikes that can momentarily
overload the input stage of the amplifier.
