SWITCHING CHARACTERISTICS (continued)
(Typical Operating Circuit, VCC = +5V ±5%, RPSET = 0 (MAX3292), VCC = VCCD (MAX3292), TA = +25°C, unless otherwise noted.
Typical values are at VCC = +5V and TA = +25°C.)
Note 1: All currents into the device are positive; all currents out of the device are negative. All voltages are referenced to device
ground unless otherwise noted.
Note 2: Guaranteed by design.
Note 3: DPER is defined as (VODP / VOD).
Note 4:
VODP and VOC are the changes in VDD and VOC, respectively, when the DI input changes. This specification reflects
constant operating conditions. When operating conditions shift, the maximum value may be momentarily exceeded.
Note 5:
VODP and VOC are the changes in VOD and VOC, respectively, when the DI input changes state.
Note 6: Maximum current level applies to peak current just prior to foldback-current limiting; minimum current level applies during
current limiting.
Note 7: Shutdown is enabled by bringing RE high and DE low. If the enable inputs are in this state for less than 50ns, the device is
guaranteed not to enter shutdown. If the enable inputs are in this state for at least 500ns, the device is guaranteed to have
entered shutdown. Time to shutdown for the device (tSHDN) is measured by monitoring R0 as in Figure 4.
