VCC Positive Analog Supply Input
PMU-B Range-Setting-Resistor Common Connection. Connect to one end of all the range-
RBCOM setting resistors (RB_) for PMU-B. Also serves as the input to an external current-range buffer
for PMU-B.
RBE PMU-B Range E Resistor Connection
RBD PMU-B Range D Resistor Connection
RBC PMU-B Range C Resistor Connection
RBB PMU-B Range B Resistor Connection
RBA PMU-B Range A Resistor Connection
FORCEB PMU-B Driver Output. Forces a current or voltage to the DUT for PMU-B.

SENSEB PMU-B Sense Input. A Kelvin connection to the DUT. Provides the feedback signal in FVMI
mode and the measured signal in FIMV mode for PMU-B.

CC1B
PMU-B Compensation Capacitor Connection 1. Provides compensation for the PMU-B main
amplifier.

5
CC2B PMU-B Compensation Capacitor Connection 2. Provides compensation for the PMU-B main
amplifier.

RXDB
PMU-B Current-Range Sense-Resistor Connection. Connects to the external current-range
sense resistor on the DUT side for PMU-B. See Figure 5.

3
RXAB
PMU-B Current-Range Sense-Resistor Connection. Connects to the external current-range
sense resistor on the amplifier side for PMU-B. See Figure 5.
17
64
CS Chip-Select Input. Force CS low to enable communication with the serial port.
18
63
LOAD Serial Port Load Input. A logic low asynchronously loads data from the input registers into the
PMU registers.

DUTHB
PMU-B Window-Comparator High-Comparator Output. A sense-B voltage above the VTHMAXB
level forces the DUTHB output low. DUTHB is an open-drain output.
22
59
DUTLB
PMU-B Window-Comparator Low-Comparator Output. A sense-B voltage below the VTHMINB
level forces the DUTLB output low. DUTLB is an open-drain output.

54, 57
EXTBSEL PMU-B External Current-Range Selector. Selects the external current range for PMU-B.
DGND Digital Ground
25
56
DOUT
Serial Data Output. Provides data out from the shift register. Facilitates daisy-chaining to DIN
of a downstream PMU.
26
55
VL Logic Supply Voltage Input. The voltage applied at VL sets the upper logic-voltage level.
28
53
EXTASEL PMU-A External Current-Range Selector. Selects the external current range for PMU-A.
29
52
DUTLA
PMU-A Window-Comparator Low-Comparator Output. A sense-A voltage below the VTHMINA
level forces the DUTLA output low. DUTLA is an open-drain output.
