LM75BGD Product details

General 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 and benefits
■ 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
■ I2C-bus interface with up to 8 devices on the same bus
■ Power supply range from 2.8 V to 5.5 V
■ Temperatures range from -55°C to +125°C
■ Frequency range 20 Hz to 400 kHz with bus fault time-out to prevent hanging up the bus
■ 11-bit ADC that offers a temperature resolution of 0.125°C
■ Temperature accuracy of:
   ♦ ±2°C from -25°C to +100°C
   ♦ ±3°C from -55°C to +125°C
■ Programmable temperature threshold and hysteresis set points
■ Supply current of 1.0 A in shutdown mode for power conservation
■ Stand-alone operation as thermostat at power-up
■ ESD protection exceeds 4500 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101
■ Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
■ Small 8-pin package types: SO8, TSSOP8, 3 mm x 2 mm XSON8U,
   and 2 mm x 3 mm HWSON8

Applications
■ System thermal management
■ Personal computers
■ Electronics equipment
■ Industrial controllers
