PCT2075

I2C-bus Fm+ digital temperature sensor and thermal watchdog

2. Features and benefits

 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

 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 to Fast-mode and Standard-mode

 11-bit ADC that offers a temperature resolution of 0.125 C

 Temperature accuracy of:

 1 C (max.) from 25 C to +100 C

 2 C (max.) from 55 C to +125 C

 Programmable temperature threshold and hysteresis set points during operation

 Supply current of <1.0 A in shut-down mode for power conservation

 Stand-alone operation as thermostat at power-up

 ESD protection exceeds 2000 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 and 2 mm  3 mm HWSON8

 Small 6-pin package type: TSOP6

3. Applications

 System thermal management

 Personal computers

 Electronics equipment

 Industrial controllers
