7 revision 3 / december 18, 2002 www .semtech.com test and measurement products edge4707b force current mode in the fi mode (fv/fi* = 0), ivin is a high impedance analog voltage input that is converted into a current at the force pin using the following relationship: forced current = ivin / rext (positive current is defined as current flowing out of the force pin.) the ivin input voltage range and forced cur- rent (at force) can be seen in table 4. table 4. measure voltage mode in the mv mode (mi/mv* = 0), dut voltage is measured via the sense input pin. note that ext_sense_sel = 0 when the edge4707b sense is used. this measured voltage is also tested with the on-board window compara- tor. comparator the edge4707b features an on-board window compara- tor which provides two-bit measurement range classifica- tion. ivmax and ivmin are high impedance analog inputs that establish the upper and lower thresholds for the win- dow comparator. in the mi mode, an i/v max input of +2v will set the upper threshold of the window comparator to a voltage corresponding to +fsc (full-scale current), and an i/v min input of 2v will set the lower threshold to a voltage corresponding to fsc (positive current is defined as current flowing out of the pmu). dutgtl the dutlth are lvttl compatible outputs which indicate the range of the measured parameter in relation to ivmin and ivmax. comparator functionality is sum- marized in table 5 for mi mode and table 6 for mv mode. circuit description (continued) ivmon ivmon is a real time analog voltage output which tracks the sensed parameter. in the mv mode, the output voltage displayed at ivmon is a 1:1 mapping of the sense voltage. in the mi mode, ivmon follows the equation: ivmon = i(measured) * rext using nominal values for the external resistors (ra, rb, rc, and rd), a voltage at ivmon of +2v corresponds to imax and 2v corresponds to imin of the selected current range. the ivmon pin can also be placed into a high impedance state by using the disable input (see table 3). table 3. force voltage mode in the fv mode (fv/fi* = 1), vinp is a high impedance analog voltage input that maps directly to the voltage forced at the force pin. measure current mode in the mi mode (mi/mv* = 1), a current monitor is connected in series with the pmu forcing amplifier. this monitor generates a voltage that is proportional to the current passing through it, and is brought out to ivmon. this voltage (corresponding to the measured current) is also tested by the on-board window comparator. e l b a s i d* v m / i mr e t e m a r a p d e s n e s 1x e c n a d e p m i h g i h 00 e g a t l o v d e r u s a e m 01 t n e r r u c d e r u s a e m n i v i g n i d n o p s e r r o c t n e r r u c d e c r o f v 2 +) e l a c s l l u f ( x a m i v 00 v 2 ) e l a c s l l u f ( n i m i
