SA56004ED中文资料恩XP数据手册PDF规格书

General description

The 恩XP Semiconductors SA56004X is an SMBus compatible, 11-bit remote/local digital temperature sensor with overtemperature alarms. The remote channel of the SA56004X monitors a diode junction, such as a substrate PNP of a microprocessor or a diode connected transistor such as the 2N3904 (NPN) or 2N3906 (PNP). With factory trimming, remote sensor accuracy of ±1 °C is achieved.

特性 Features

■ Accurately senses temperature of remote microprocessor thermal diodes or diode

connected transistors within ±1 °C

■ On-chip local temperature sensing within ±2 °C

■ Temperature range of −40 °C to +125 °C

■ 11-bit, 0.125 °C resolution

■ 8 different device addresses are available for server applications. The SA56004ED

with marking code 56004E, and SA56004EDP with marking code 6004E are address

compatible with the National LM86, the MAX6657/8 and the ADM1032.

■ Offset registers available for adjusting the remote temperature accuracy

■ Programmable under/overtemperature alarms: ALERT and T_CRIT

■ SMBus 2.0 compatible interface, supports TIMEOUT

■ Operating voltage range: 3.0 V to 3.6 V

■ I2C-bus Standard-mode and Fast-mode compatible

■ SO8, TSSOP8 and HVSON8 packages

■ Programmable conversion rate (0.0625 Hz to 26 Hz)

■ Undervoltage lockout prevents erroneous temperature readings

■ Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA

Applications

■ System thermal management in laptops, desktops, servers and workstations
