11 / 108 page  2014 Microchip Technology Inc. DS20005334A-page 11 UCS81003 Primary Removal Detection Threshold IREM_QUAL_ACT — 700 — µA Programmable 100 – 900 µA, default listed, Active Power state — 800 — µA Programmable 200 – 1000 µA, default listed, Detect power state (see Section 8.4 “Removal Detection”). Attach/Removal Detection - AC Attach Detection Time tDET_QUAL — 100 — ms Time from Attach to A_DET# assert Removal Detection Time tREM_QUAL — 1000 — ms Allowed Charge Time tDET_CHARGE —800 — ms CBUS = 500 µF maximum, Programmable 200 – 2000 ms, default listed. Charger Emulation Profile General Emulation - DC Charging Current Threshold IBUS_CHG —175.8 — mA Default Charging Current Threshold Range IBUS_CHG_RNG 11.72 — 175.8 mA Note 5 DP-DM Shunt Resistor Value RDCP_RES — 200 Connected between DPOUT and DMOUT, 0V < DPOUT = DMOUT < 3V Response Magnitude (voltage divider option resistance range) SX_RXMAG_DVDR 93 — 200 k Note 5 Resistor Ratio Range (voltage divider option) SX_RATIO 0.25 — 0.66 V/V Note 5 Resistor Ratio Accuracy (voltage divider option) SX_RATIO_ ACC — ±0.5 — % Average over range Response Magnitude (resistor option range) SX_RXMAG_RES 1.8 — 150 k Note 5 Internal Resistor Tolerance (resistor option) SX_RXMAG_RES _ACC — ±10 — % Average over range Response Magnitude (voltage option range) SX_RXMAG_VOLT 0.4 — 2.2 V Note 5 Voltage Option Accuracy SX_RXMAG_VOLT _ACC — ±1 — % No load, average over range Voltage Option Accuracy SX_RXMAG_VOLT _ACC_ 150 — -6 — % 150 µA load, average over range Voltage Option Accuracy SX_RXMAG_VOLT _ACC_ 250 — -10 — % 250 µA load, average over range TABLE 1-2: ELECTRICAL CHARACTERISTICS (CONTINUED) Electrical Characteristics: Unless otherwise specified, VDD = 4.5V to 5.5V, VS = 2.9V to 5.5V, VPULLUP = 3V to 5.5V, TJ = -40°C to +125°C; all Typical values at VDD = VS = 5V, TJ = +27°C. Characteristic Sym. Min. Typ. Max. Unit Conditions 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 is 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 UCS81003 cannot report values above ILIM (if IBUS_R2MIN ILIM) or above IBUS_R2MIN (if IBUS_R2MIN > ILIM and ILIM 1.68A). 5: The Minimum and Maximum values represent the boundaries of a programmable range. Each value in the range is typical. |
