9 / 108 page  2014 Microchip Technology Inc. DS20005334A-page 9 UCS81003 Port Power Switch - AC Parameters Turn-On Delay tON_PSW — 0.75 — ms PWR_EN active toggle to switch on time, VBUS discharge not active. Turn-Off Time tOFF_PSW_INA — 0.75 — ms PWR_EN inactive toggle to switch off time CBUS = 120 µF Turn-Off Time tOFF_PSW_ERR — 1 — ms Overcurrent Error, VBUS Min Error, or Discharge Error to switch off, CBUS = 120 µF Turn-Off Time tOFF_PSW_ERR — 100 — ns TSD or back-drive error to switch off, CBUS = 120 µF VBUS Output Rise Time tR_BUS — 1.1 — ms Measured from 10% to 90% of VBUS, CLOAD = 220 µF, ILIM = 1.0A Soft Turn-On Rate I BUS/t —100 — mA/µs Temperature Update Time tDC_TEMP — 200 — ms Programmable 200 - 1600 ms, default listed Short-Circuit Response Time tSHORT_LIM — 1.5 — µs Time from detection of short to current limit applied. No CBUS applied. Short-Circuit Detection Time tSHORT — 6 — ms Time from detection of short to port power switch disconnect and ALERT# pin assertion. Latched Mode Cycle Time tUL — 7 — ms From PWR_EN edge transition from inactive to active to begin error recovery. Auto-Recovery Mode Cycle Time tCYCLE — 25 — ms Time delay before error condition check. Programmable 10-25 ms, default listed. Auto-Recovery Delay tRST — 20 — ms Portable device attached, VBUS must be VTEST after this time. Programmable 10-25 ms, default listed. Discharge Time tDISCHARGE — 200 — ms Amount of time discharge resistor applied. Programmable 100-400 ms, default listed. 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. |
