Part Number : LM75B
Function : Digital temperature sensor and thermal Watchdog
Package : 8-VSSOP Type
Maker : NXP Semiconductors.
Pinouts : 
Description :
The LM75B is a temperature-to-digital converter using an on-chip band gap temperature sensor and Sigma-Delta A-to-D conversion technique with an overtemperature detection output. The LM75B contains a number of data registers: Configuration register (Conf) to store the device settings such as device operation mode, OS operation mode, OS polarity and OS fault queue as described in Section 7 “Functional description”; temperature register (Temp) to store the digital temp reading, and set-point registers (Tos and Thyst) to store programmable overtemperature shutdown and hysteresis limits, that can be communicated by a controller via the 2-wire serial I2C-bus interface. The device also includes an open-drain output (OS) which becomes active when the temperature exceeds the programmed limits. There are three selectable logic address pins so that eight devices can be connected on the same bus without address conflict.
The LM75B can be configured for different operation conditions. It can be set in normal mode to periodically monitor the ambient temperature, or in shutdown mode to minimize power consumption. The OS output operates in either of two selectable modes: OS comparator mode or OS interrupt mode. Its active state can be selected as either HIGH or LOW. The fault queue that defines the number of consecutive faults in order to activate the OS output is programmable as well as the set-point limits.
Features
1. Pin-for-pin replacement for industry standard LM75 and LM75A and offers improved
temperature resolution of 0.125'C and specification of a single part over power supply
range from 2.8 V to 5.5 V
2. I2C-bus interface with up to 8 devices on the same bus
3. Power supply range from 2.8 V to 5.5 V
4. Temperatures range from -55'C to +125'C
5. Frequency range 20 Hz to 400 kHz with bus fault time-out to prevent hanging up the
bus
6. Programmable temperature threshold and hysteresis set points
7. Stand-alone operation as thermostat at power-up
8. Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
9. Small 8-pin package types: SO8, TSSOP8, 3 mmx2 mm XSON8U, and
2mmx3mmHWSON8
