Si85xx
As explained in Section “2.3. Integrator Reset and Current Measurement”, the signals applied to R1–R4 can
control integrator reset in real time (Option 1), or they can trigger a reset event of programmable duration (Option
2). Referring to Figure 14, reset timing is exclusively a function of the signals applied to R1–R4 when TRST is tied
to VDD.
If not connected to VDD, the reset timer is enabled, and TRST must be connected through a resistor to ground to
set the reset duration (t R ). Note that the reset timer is retriggerable and generates a timed integrator discharge
pulse whenever the reset logic output transitions from low to high.
