G753 Global Mixed-mode Technology High Accuracy Digital Temperature Sensor and Thermal Watchdog with Two-Wire Interface Features General Description The G753 is a temperature sensor, analog-to-digital converter, and digital over- temperature detector with SMBus interface. The host can query the G753 at any time to read temperature. The open-drain ALERT# output becomes active when the temperature exceeds a programmable limit which initialed by hardware power-on setting. This pin can operate in either “Comparator” or “Interrupt” mode. SMBus interface Hardware Power-on Setting & Programmable over temperature limit Separate open-drain output pin operates as interrupt or comparator at output Register readback capability Power up defaults permit stand-alone operation as thermostat Shutdown mode to minimize power consumption Applications System Thermal Management Personal Computers Office Electronics Electronic Test Equipment Key Specifications Supply Voltage Supply Current operating 3.0V to 3.6V 110µA (typ) 130µA (max) 1µA (max) shutdown Temperature Accuracy -10°C to 80°C ±1°C (max) -55°C to 125°C ±3°C (max) Ordering Information ORDER NUMBER MARKING PACKAGE (Green) G753T11U 753xx SOT-23-5 Note: T1: SOT-23-5 1 : Bonding Code U: Tape & Reel Pin Configuration Typical Application Circuit +VS 3V to 3.6V G753 SMBCLK 1 GND 2 5 4 SMBDATA 5 SMBDATA G753 SMBCLK ALERT# Typical Bypass 0.1µF (Unless mounted close to Processor) 3 4 1 +VS SOT-23-5 2 3 ALERT# To Processor Interrupt Line ALERT# Set for active low for wire OR’d multiple interrupt line TEL: 886-3-5788833 http://www.gmt.com.tw Ver: 0.4 Oct 16, 2013 1
