TABLE 1-2: ELECTRICAL CHARACTERISTICS Electrical Characteristics: Unless otherwise specified, VDD = 4.5V to 5.5V, VS = 2.9V to 5.5V, VPULLUP = 3V to 5.5V, TA = -40°C to +85°C; all Typical values at VDD = VS = 5V, TA = +27°C. Characteristic Sym. Min. Typ. Max. Unit Conditions Power Supply Supply Voltage VDD 4.5 5 5.5 V (Note 1) Source Voltage VS 2.9 5 5.5 V (Note 1) Supply Current in Active (IDD_ACTIVE + IVS_ACT) IACTIVE — 650 750 µA Average current, IBUS =0 mA Supply Current in Sleep (IDD_SLEEP + IVS_SLEEP) ISLEEP — 5 15 µA Average current, VPULLUP VDD Supply Current in Detect (IDD_DETECT + IVS_DETECT) IDETECT — 185 — µA Average current, no portable device attached Power-on Reset VS Low Threshold VS_UVLO —2.5 — V VS voltage increasing VS Low Hysteresis VS_UVLO_HYST —100 — mV VS voltage decreasing VDD Low Threshold VDD_TH —4 — V VDD voltage increasing VDD Low Hysteresis VDD_TH_HYST —500 — mV VDD voltage decreasing I/O Pins – SMCLK (UCS1003-1), SMDATA (UCS1003-1), EM_EN, M1, M2, PWR_EN, S0, LATCH, ALERT#, A_DET# (UCS1003-1 and UCS1003-3), CHRG# (UCS1003-2) – DC Parameters Output Low Voltage VOL —— 0.4 V ISINK_IO = 8 mA, SMDATA, ALERT#, A_DET#, CHRG# Input High Voltage VIH 2.0 — — V PWR_EN, EM_EN, M1, M2, LATCH, S0, SMDATA, SMCLK Input Low Voltage VIL — — 0.8 V PWR_EN, EM_EN, M1, M2, LATCH, S0, SMDATA, SMCLK Leakage Current ILEAK — — ±5 µA Powered or unpowered, VPULLUP VDD Interrupt Pins – AC Parameters ALERT#, A_DET# Pins Blanking Time tBLANK —25 — ms ALERT# Pin Interrupt Masking Time tMASK —5 — ms SMBus/I2C Timing (UCS1003-1 only) Input Capacitance CIN —5 — pF Clock Frequency fSMB 10 — 400 kHz Spike Suppression tSP —50 ns (Note 2) Bus Free Time Stop to Start tBUF 1.3 — — µs Note 1: For split supply systems using the Attach Detection feature, VS must not exceed VDD +150 mV. 2: This parameter is ensured by design and not 100% tested. 3: This parameter is characterized, but not 100% production tested. 4: The current measurement full-scale range maximum value is 3.0A. However, the UCS1003-1 cannot report values above ILIM (if IBUS_R2MIN ILIM) or above IBUS_R2MIN (if IBUS_R2MIN > ILIM and ILIM 1.68A). 5: The Min and Max values represent the boundaries of a programmable range for UCS1003-1 only. Each value in the range is typical. |
