5 / 30 page  LTC2952 5 2952fa Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The greatest of V1, V2 or VS is the internal supply voltage (VMAX). Note 3: All currents into pins are positive; all voltages are referenced to GND unless otherwise noted. Note 4: V2PREF_TH is the minimum voltage level at which V2 becomes the preferential source of quiescent current when both of the ideal diodes are off. Note 5: VS is stepped from (V1 or V2) + 0.2V to (V1 or V2) – 0.2V to trigger the event. The gate voltages are initially VG(OFF). Note 6: VS is stepped from VX – 0.2V to VX + 0.2V to trigger the event. Gate voltages are initially clamped at VG(ON). Note 7: The adjustable turn-on and turn-off timer period is the adjustable debounce period following the Internal default-on and default-off timer period, respectively. ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. V1 = V2 = VS = 2.7V to 28V unless otherwise noted. (Notes 2, 3) SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS μP Handshake Timing tINT(MIN) INT Minimum Pulse Width Minimum Measured Time PB Rising to INT Rising l 10 50 250 μs tKILL(PW) KILL Minimum Pulse Width Full Swing Pulse From 5V to 0V l 150 500 μs tKILL,ON BLANK KILL On Blanking (Note 9) KILL = 0V, Measured Time Between EN Rising → EN Falling l 270 400 530 ms tKILL, OFF WAIT KILL Wait Time (Note 10) KILL = 1V, COFFT = OPEN, Measured Time Between INT Falling → EN Falling l 270 400 530 ms tEN, LOCKOUT Enable Lockout Time (Note 11) Measured Time Between EN Falling → EN Rising l 270 400 530 ms Note 8: The input current to the three-state WDE pin are the pull-up and the pull-down current when the pin is either set to 3.3V or GND, respectively. In the open state, the maximum pull-up or pull-down leakage current permissible is 10μA. Note 9: The turn-on KILL blanking time is the waiting period immediately following the EN pin switching high; at the end of this period the input to the KILL needs to be high to indicate that the system has powered up properly, otherwise the EN pin is immediately switched low. Note 10: The KILL wait time during the power-down process is the wait period immediately following a valid turn-off command until the EN pin switches low. Note 11: The enable lockout time is the minimum wait time between the last falling edge and the next rising edge on the EN pin. |
