NAME

FUNCTION

Operating voltage for all circuitry that connects to the controlling

microprocessor (TXD, RXD, START, SPU, DONE pins).

V_CCQ

This line is used to control the external strong pullup function. When SPU is

low, the strong pullup (PCTLZ) is high. When SPU is high and TXD is low,

PCTLZ is low.

SPU

This line acts as an enable control for the DONE pin. If START is high, then

START DONE reflects the filtered digital output of the current-sense comparator. If

START is low, then DONE is low.

When TXD is low, the I/O pin is pulled resistively to V_CC. When TXD is

high, the 1-Wire bus is pulled to GND (for write-0, write-1, read, and reset

low times).

1-Wire Data

This line returns the digital state of the 1-Wire bus, level-shifted to swing

between V_CCQand GND.

RXD

This line is high only when the buffered, filtered digital output from the

DONE current-sense comparator indicates that the downstream 1-Wire slave device

is no longer sinking high current. This signal is enabled if START is high.

Active-low control pin for an external low-on-resistance, high-current

PCTLZ supply. This signal typically controls the gate of a P-channel MOSFET. This

signal is low when SPU is high and TXD is low.
