Maxim Integrated
A digital output decoded from the range select bits,
EXTSEL_, indicates when to activate the booster.
CCOM_ serves as an input to an external buffer through
an internal 50
Ω current-limit series resistor. Connect the
external buffer output to the external current-sense resis-
tor, REXT, and to R_X. Connect the other side of REXT to
FORCE_. Ensure that the external switch is low leakage.
Voltage Clamps
The voltage clamps limit FORCE_ and operate over the
entire specified current range. Set the clamp voltages
externally at CLHI_ and CLLO_. The voltage at FORCE_
triggers the clamps independent of the voltage at
SENSE_. When enabled, the clamps function in FI
mode only. Use clamp voltages of 0.7V above and
below the FORCE_ voltage range to ensure proper
operation of the PMU.
Current Limit
The FORCE_ current-limiting circuitry, 92mA (maximum),
ensures a well-behaved MSR_ output for currents
between the full current range and the current limits. For
currents greater than the full-scale current, the MSR_
voltage is greater than +4V, and for currents less than
the full-scale current, the MSR_ voltage is less than -4V.
Additionally, serial interface bit B2 enables a range-sen-
sitive current limit of 2.5 times the nominal current range.
Table 9 shows the current-limit operation.
Independent Control of the Feedback
Switch and the Measure Switch
Two single-pole-double-throw (SPDT) switches deter-
mine the mode of operation of the PMU. One switch
determines whether the sensed DUT current or DUT
voltage feeds back to the input, and thus determines
whether the MAX9951/MAX9952 force current or volt-
age. The other switch determines whether MSR_ sens-
es the DUT current or DUT voltage.
Independent control of these switches and the HI-
ZFORCE state permits flexible modes of operation
beyond the traditional force-voltage/measure-current
(FVMI) and force-current/measure-voltage (FIMV)
modes. The MAX9951/MAX9952 support the following
eight modes:
FVMI
FIMV
FVMV
FIMI
FNMV
FNMI (range E only)
Terminate/Measure V
Terminate/Measure I
Figure 6 shows the internal path structure for force-volt-
age/measure-current mode. In force-voltage/measure-
current mode, the current across the appropriate
external sense resistor (R_A to R_E) provides a voltage
at MSR_. SENSE_ samples the voltage at the DUT and
feeds the buffered result back to the negative input of
the voltage amplifier. The voltage at MSR_ is propor-
tional to the FORCE_ current in accordance with the fol-
lowing formula:
VMSR_ = IFORCE_ x RSENSE x 4
Figure 7 shows the internal path structure for the force-
current/measure-voltage mode. In force-current/mea-
sure-voltage mode, the appropriate external sense
resistor (R_A to R_E) provides a feedback voltage to
