Current-Range Selection
Three bits from the control word, RS0, RS1, and RS2,
control the full-scale current range for either FI (force
current) or MI (measure current). Table 6 describes the
full-scale current-range control.
Clamp Enable
The CLENABLE bit enables the force-output-voltage
clamps when high and disables the clamps when low.
There is hysteresis equal to approximately 5% of the
current range for clamp when serial bit B1 is 1. For bit
B1 = 0, no hysteresis, but clamp voltage is less accurate.
Measure Output High-Impedance Control
MSR_ attains a low-leakage, high-impedance state by
using the
HI-ZMSR control bit, or the HI-Z_ input. HI-Z_ is
internally pulled up to VL with a 1.5M
Ω resistor. The 2
bits are logically ANDed together to control the MSR_
output. HI-Z_ allows external multiplexing among several
PMU MSR_ outputs without using the serial interface.
Table 7 explains the various output modes for the MSR_
output.
Digital Output (DOUT)
The digital output follows the last output of the serial-
shift register and clocks out on the falling edge of
SCLK. DOUT serially shifts the first bit of the incoming
serial data word 16.5 clock cycles later. This allows for
daisy-chaining additional devices using DOUT and the
same clock.
