Si85xx
Integrator reset Option 1 is selected by connecting T RST
to VDD. In this mode, the Si85xx is held in reset as long
as the signals on R1–R4 satisfy the logic equations of
gate drivers are external to the system controller IC (the

The Si85xx’s absolute accuracy is affected by the
following factors:

Reset Option 2 is selected by connecting a timing
resistor (R TRST in Figure 5) from the TRST input to
ground. It is typically used in applications where the
gate drivers are on-board the controller. In this mode,
the on-chip reset timer is triggered when the signals on
R1–R4 satisfy the logic equations in Table 11. Once
triggered, the timer maintains integrator in reset for time
duration t R as programmed by the value of resistor
R TRST . The user must select the value of resistor R TRST
to terminate the reset cycle prior to the start of
measurement under worst-case timing conditions. Note
that values of t R below the specified value in "1.
integrator output offset error and increased output noise
operating conditions that can ultimately affect the
absolute measurement accuracy of the Si85xx. The
total worst-case accuracy at full scale can be estimated
by the sum of the initial accuracy (up to ±5%) plus aging
(up to ±1.5%) and supply variations (up to ±3.5%). For
example, the total measurement error expected for a
device operating at a given V DD supply of 5 V (±10%) is
10% if the device is operated over a temperature range
of –40 to 125 °C for up to 10 years. If the temperature
range is limited to 0 to 85 °C, the measurement error
can be improved by up to 2%. See Figure 6 for details.

following equation (see Table 9):
t R = 10 ns/k ?
where values of R TRST that produce a reset time less
than 150 ns (R TRST < 15 k ? ) should not be used.

Resistance
(output offset voltage) is calibrated out each time VDD is
applied to the Si85xx; so, its error contribution is
minimized when the temperature at which calibration
occurred is at or near the steady-state operating
temperature of the Si85xx. For example, applying VDD
at 25 °C (offset cal is performed) and operating at 85 °C
will result in a larger offset error than operating at 50 °C.
The effect of this error is summarized in Figure 6. The
chart is referenced to 25 °C. If the Si85xx is powered up
at 25 °C and then operated at 125 °C with no auto-
calibration performed (i.e., the power is not cycled at
125 °C, which causes an auto-calibration), a 3%
