Overview
DS75LV Digital Thermometer and Thermostat www.
maxim-ic.
com DESCRIPTION This low-voltage (1.
7V to 3.
7V) digital thermometer and thermostat provides 9-, 10-, 11-, or 12-bit digital temperature readings over a -55°C to +125°C range with ±2°C accuracy over a -25°C to +100°C range.
At power-up, the DS75LV defaults to 9-bit resolution for software compatibility with the LM75.
Communication with the DS75LV is achieved through a simple 2-wire serial interface.
Three address pins allow up to eight www.
DataSheet4U.
com DS75LV devices to operate on the same 2-wire bus, which greatly simplifies distributed temperaturesensing applications.
The DS75LV thermostat has a dedicated open-drain output (O.
S.
) and programmable fault tolerance, which allows the user to define the number of consecutive error conditions that must occur before O.
S is activated.
There are two thermostatic operating modes that control thermostat operation based on user-defined trip-points (TOS and THYST).
A block diagram of the DS75LV is shown in Figure 1 and detailed pin descriptions are given in Table 2.
