PCT2075 Datasheet

PCT2075 digital temperature sensor

The PCT2075 is a temperature-to-digital converter featuring ±1 °C accuracy over -25 °C to +100 °C range. It uses an on-chip band gap temperature sensor and Sigma-Delta Ato-D conversion technique with an overtemperature detection output that is a drop-in replacement for other LM75 series thermal sens.

Features

• Pin-for-pin replacement for LM75 series but allows up to 27 devices on the bus
• Power supply range from 2.7 V to 5.5 V
• SDA and SCL inputs are overvoltage tolerant to 5.5 V NXP Semiconductors PCT2075 I2C-bus Fm+, 1 °C accuracy, digital temperature sensor and thermal watchdog
• SDA and OS open drain outputs can be pulled up to 5.5 V regardless of supply voltage
• Temperatures range from -55 °C to +125 °C
• Frequency range 20 kHz to 1 MHz with SMBus time-out to prevent hanging up the bus
• 1 MHz Fast-mode Plus 30 mA SDA drive allows more devices on the same bus but is backward compatible.
