Texas Instruments LM57BISD-5/NOPB Temperature Sensor IC Open Drain Push Pull ± 1.5°C -50 °C 150 Wson 8 Pins

The LM57BISD-5/NOPB is a precision Temperature Switch and Analogue Temperature Sensor for wide temperature applications. The trip temperature (TTRIP) is selected from 256 possible values in the range of -40 to 150°C. The VTEMP is a class AB analogue voltage output that is proportional to temperature with a programmable negative temperature coefficient (NTC). Two external 1% resistors set the TTRIP and VTEMP slope. The digital and analogue outputs enable protection and monitoring of system thermal events Built-in thermal hysteresis (THYST) prevents the digital outputs from oscillating. assert when the temperature falls below a temperature equal to TTRIP minus THYST. Trip Temperature Set by External Resistors with Accuracy of ±1.7°C or ±2.3°C from -40 to +150°C.

• Resistor tolerance contributes zero error
• Push-pull and Open-drain switch outputs
• Very linear analogue VTEMP sensor output with ±0.8°C or ±1.3°C accuracy from -50 to +150°C
• Short-circuit protected analogue and digital outputs
• Latching function for digital outputs
• TRIP-TEST pin allows in-system testing
• Low power minimizes self-heating to under 0.02°C
• Green product and no Sb/Br

Applications

Sensing & Instrumentation, Automation & Process Control, Industrial, Automotive, Communications & Networking, Avionics
