I/VIN pin (please refer to block diagram). The I/VM pin
provides a voltage proportional to the DUT current.
V(I/VM) = (4 x R x I(DUT)), where R is the external range
resistor (0.05% tolerance) and I(DUT) is the current sup-
plied to the load. The resistors in the application circuit were
chosen using this formula R range = (2V/Imax), for Range A
this is RA = 2/20
m
A or 100K.
When SI/V is high the RC7352 will force current and
measure voltage. The range select pins RS1 and RS2 control
the maximum output current (see Table 1), while magnitude
of the forced current is given by the expresion
I(DUT) = V(I/VIN)/(4 x R)
where R is the range resistor. In the FI/MV mode the voltage
at the I/VM pin equals the device voltage. The I/VM pin can
be connected to an A/D convertor to monitor the current or
voltage at the load device.
The RC7352 also has a window comparator that can provide
upper or lower limit fail information. I/Vmx and I/Vmn are
voltage inputs for the upper and lower limits respectively.
You must use the formulas listed above to calculate current
limits for each range while voltage limits are 1:1. Their
corresponding outputs, VHF (V high fail) and VLF (V low
fail) can be used individually or “Wire ORed” to obtain a
composite signal. Additionally the VDIS pin can be set high
to disable the window comparator and its I/O lines. Although
this reduces overall power consumption, it also disables the
I/VM output.
