4 / 34 page Si7006-A10 4 Rev. 1.1 1. Electrical Specifications Unless otherwise specified, all min/max specifications apply over the recommended operating conditions. Table 1. Recommended Operating Conditions Parameter Symbol Test Condition Min Typ Max Unit Power Supply VDD 1.9 — 3.6 V Operating Temperature TA –40 — +125 °C Table 2. General Specifications 1.9 < VDD < 3.6 V; TA = –40 to 125 °C default conversion time unless otherwise noted. Parameter Symbol Test Condition Min Typ Max Unit Input Voltage High VIH SCL, SDA pins 0.7xVDD —— V Input Voltage Low VIL SCL, SDA pins — — 0.3xVDD V Input Voltage Range VIN SCL, SDA pins with respect to GND 0.0 — VDD V Input Leakage IIL SCL, SDA pins — — 1 μA Output Voltage Low VOL SDA pin; IOL = 2.5 mA; VDD = 3.3 V — — 0.6 V SDA pin; IOL = 1.2 mA; VDD = 1.9 V — — 0.4 V Current Consumption IDD RH conversion in progress — 150 180 μA Temperature conversion in progress — 90 120 μA Standby, –40 to +85 °C2 — 0.06 0.62 μA Standby, –40 to +125 °C2 — 0.06 3.8 μA Peak IDD during powerup3 — 3.5 4.0 mA Peak IDD during I2C operations4 — 3.5 4.0 mA After writing to user registers5 —20 — μA Heater Current6 IHEAT — 3.1 — mA Notes: 1. Initiating a RH measurement will also automatically initiate a temperature measurement. The total conversion time will be tCONV(RH) + tCONV(T). 2. No conversion or I2C transaction in progress. Typical values measured at 25 °C. 3. Occurs once during powerup. Duration is <5 msec. 4. Occurs during I2C commands for Reset, Read/Write User Registers, Read EID, and Read Firmware Version. Duration is <100 μs when I2C clock speed is >100 kHz (>200 kHz for 2-byte commands). 5. IDD after a user register write. Initiating any other subsequent I2C transaction on the same bus (such as the user register read, starting an RH measurement, or traffic directed at other I2C devices) will transition the device to standby mode. 6. Additional current consumption when HTRE bit enabled. See Section “5.5. Heater” for more information |
